This research improves upon previous efforts by presenting a novel application programming interface API -enabled approach to a automatically collect detailed model development data directly from BIM software packages in real-time, and b efficiently calculate several modeling performance measures during schematic and design development phases of building projects.
These indicators can be used to properly arrange modeling teams in the quest for high-quality building models. The specific objectives of this study to examine the feasibility of a proposed automated design performance measurement framework, and to identify optimal modeling team configurations using empirical performance information. A passive data recording approach allows for the real-time capture of comprehensive user interface UI interaction and model element modification events.
The proposed framework is implemented as an Autodesk Revit plugin. Next, an experiment is conducted to capture data using the developed Revit plugin.
Experiment participants’ individual production rates are estimated to establish the validity of the proposed approach to identify the optimal design team configuration. The presented approach uses the earliest due date EDD sequencing rule in combination with the critical path method CPM to calculate the maximum lateness for different design team arrangements.
Martin Margreiter. Within the scope of this bachelor thesis a program was developed for designing and subsequently editing two-dimensional scenarios for a simulation of critical crowd. With the aid of this so-called SinoGen generator and itsgraphical interface a user can create new topography files and save them in the required file format XML for a subsequent simulation. For this purpose a DXF parser was developed for picking simple two-dimensional geometric elements from a CAD drawing and for using them true to scale in a simulation of crowds.
Besides the reading of existing information on simulating an environment, the program should provide the opportunity to add new elements. Needed for a simulation are inter alia sources, to generate new pedestrian and targets, to remove persons from the topograhy again, after a fully simulated sidewalk.
In addition, there was a need for obstacles and so-called pedestrian blocks representing a large number of crowded people at the beginning of a simulation.
Eduardo Toledo Santos. As an example, you can use quick select to make a selection set containing all circles of the drawing with the radius of a particular value.
You can paste the copied objects from the clipboard to your drawing using this command. Using this command you can find lots of properties of an object like the layer they are on, area, length or radius, perimeter or circumference and a lot more.
To use this command simply type LIST on the command line then press enter and select the object from the drawing area about which you want to know and press enter again. Using this command you can change the text justification of Text and Mtext elements in the drawing. This command was introduced in AutoCAD version and it can be used to make most of the dimensions like Linear, aligned, radius, diameter and baseline.
If you want to add a feature control frame representing tolerance-related information in your drawing then you can use this command.
Using this command you can make a multiline geometry which contains multiple parallel lines. Using this command you can change the scale of the existing Text or Mtext object in the drawing.
When the scale of these text entities is changed the base point will remain fixed. Using this command you can change the base point of a drawing without changing its origin. This is especially helpful in the situation where you want to insert the drawing into another as an Xref. By default, AutoCAD takes origin as the base point which can be modified using this command without changing the origin.
This command can be used to find the coordinate values of a point in AutoCAD drawing. Using this command you can set the drawing units and other settings like the precision of linear and angular dimensions and default rotation angle. You can insert a block or a drawing as a block in the table using this command. I have made a simple table by importing blocks of the design center as shown in the image below.
As the name suggests this command can be used to find the area of closed or open shapes in the AutoCAD drawing. Using this command you can reorient text entities in the best readable position. In image A below the text is oriented at different angles and in some situations, the text is not properly readable.
Using this command you can insert existing blocks of a drawing as a rectangular array component. Using this command you can extract closed boundaries from any enclosed area. This boundary can be used to find the area of the enclosed region or for many other applications. Using this command you can convert a text object into a Mtext object and you can also combine multiple separate Mtext objects into a single Mtext unit. This command can be used to make a dimension line inclined to a particular angle with respect to the positive side of the X-axis.
You can use this tool to make a Breakline symbol on a line. Select the starting and end points of the breakline then click at any point on the line to specify the location of breakline or directly press enter to place it exactly at the center of the line.
This command helps to join similar objects to make them a single object. For example, different lines drawn continuously can be joined to make them a polyline.
This command helps the user to stretch the object to the required length. The selection method decides the process of stretch on the object. Using this command you can create a replica of the original sketch at a specified distance from the actual sketch.
This command allows to fill up the closed area with a particular hatch pattern, gradient or solid fill. This command allows you to fill up the closed area with a particular colour gradient. You can show the file tab if it is not visible using this command. File tabs are shown in the following image. Using this command you can convert single line as well as multiline text into geometries. Using this command you can make infinite lines starting from the point of selection.
When you trim or break this infinite line to a finite length it becomes a simple line geometry. Performance Related Commands. In this section, you will find all those performance and optimization-related commands which you can use in your daily workflow.
This command can be used to remove unused named objects like layers, blocks and dimension styles from the drawing. This command can also remove the Defpoints layer and also the layer containing objects but I would not recommend that. Use this command to remove overlapping or unnecessary geometries from the drawing. This command should be used for removing errors from your drawing. Using this system variable you can turn off or on the visibility of filled area in hatches or wide polylines by changing its value to 0 or 1 respectively.
You need to regenerate the drawing using REA command after changing this system variable to see its effect on the drawing. Its default value is 1 but you can turn off this highlight effect by changing its value to 0.
When hovering the cursor over any object a preview will appear if the value of this system variable is set to 3. You can remove this preview thereby improve the performance by changing the value of this system variable to 0. You can change the value of this system variable to reduce the time it takes to save a drawing. This system variable also affects the file size of AutoCAD drawings and their compatibility with other software.
By decreasing the value of this system variable you can increase its compatibility with other software and it also decreases the size of the CAD file but the time consumed in save operation generally increases. When you increase the value of this system variable opposite happens. The default value of this system variable is 50 and it can be changed from 0 to This system variable controls the area of influence of object snap. The aperture size as defined by this system variable is the area of the square under which the point will be selected if the cursor is brought into it.
The default value of this aperture is 10 but depending on the complexity of the drawing you can change this value between The size of the aperture is relative to the current scale of the screen and it is not an absolute value. In the image below the red box not visible in AutoCAD is the aperture size for two values 10 and 50 respectively. As the name suggests this command can be used to save all of the open drawings in the AutoCAD window.
Using this system variable you can change the size of Pickbox which appears at the cursor of AutoCAD. The default value of this system variable is 3 and you can change its value from 0 to In the image below the size of Pickbox is 3 for the first cursor and 10 for the second cursor. AutoCAD will prompt you with the save dialogue box before closing all unsaved drawings and it will take you to start screen after closing all of the drawings.
Using this command you can close all open drawing windows except the current drawing window. This system variable will toggle the visibility of the start tab at the beginning of the AutoCAD application.
This system variable suppresses the dialog box that opens up when invoking certian commands like Save, Save As and Export. The default value of this system variable is 1 which allows the dialog box to open.
When you, however, change the value of this system variable to 0 the command will run on the command line and the dialog box will not open. This command controls the magnification with respect to the turning of the mouse wheel. Its value is between 3 and with the default value set to The higher the value more will be the effect of zoom wheel motion.
This command will bring up a quick property window, where the essential and common properties will be listed for the objects that are selected. Using this command you can shrink or expand the text entities in a drawing to fit in the required area. Using the wipeout command you can clean the background in a crowded drawing to make overlaying objects clear against the background.
In the image shown below Wipeout command has been used to clean the area around the second hook. Using this command you can convert your AutoCAD drawing from one unit to another and you can also scale the existing drawing to new scales automatically. When this system variable is ON it shows all the non-associative dimensions and multileaders with a yellow badge.
When it is set to off it shows no warning badge. Using this command you can automatically create a masking behind the text to make it clearly visible against the crowded background. In the image below Textmask has not been applied for the first case and in the second case, it has been applied. If you want to merge layers of multiple objects then this command is for you. Select any object of the target layer on which you want to transfer the selected objects and press enter again.
All the objects of the selected layer will be transferred to the end layer and also the selected layer will be removed. Using this command you can open the drafting settings window which can be used to change settings related to status bar options like object snap, polar tracking, snap and grid settings.
If for some reason you are looking to use the Tablet as a pointing and navigation device in AutoCAD then you can use this command to turn the Tablet input on and off.

To use this command type LAYMCH on the command line, press enter key, select objects whose layer assignment you want to change, press enter, select any entity of the layer you want to apply to selected objects, and press enter key again. Using this command you can check all the objects which are on a particular layer.
When you use LAYWALK command a list with all layers appears on the screen and you can click on any of the layer s from the list and objects from that layer s will only become visible in the drawing area. This tool can be used to modify the attribute information of blocks containing attributes. Using this command you can select objects which are connected to the selected object in the drawing area. This selection series continues as long as the command finds connected objects.
Using this command you can bring TEXT, Dimensions and Leader lines on the front of all underlying objects like hatches. This command is especially helpful if you want to bring multiple annotations to the front of all drawings objects without changing their draw order selectively.
Using this command you can hide all objects from the drawing area except the selected objects. By hiding unnecessary objects from drawing you can get a clean work area. Using this command you can group multiple objects as a single unit. This command is great for making groupings of the similar type of objects like a group of similar blocks.
This command can be used to bring the Design Center palette to the drawing area. Fields are dynamic text information which can add a lot of intelligence to your drawing by keeping data interlinked and updated.
Fields are extensively used in the sheet set and layout drawings and they can be used to automate a lot of information in AutoCAD drawings. Using this command you can import drawings of many different formats in AutoCAD, the list of all supported formats is shown in the image below. If you want to export a certain part of your drawing or any of its blocks to an external file then you can use write block tool or its command equivalent WBLOCK.
Using this command you can print multi-sheet files directly, unlike PLOT command which only plots single sheet this command will allow you to plot multiple sheets or even all of the sheets of the drawing directly. Using this command you can add bullet points and numbered lists along multiple rows of the text. This command is used to transfer properties like lineweight, transparency, layer, color and more from one object to another.
This command changes the scale for the Line Type and applies throughout the drawing. The current coordinate of a point can be determined using this command. This allows the user to save the drawing to a different file format as shown in the following image. Using this command the user can measure the distance , radius,area and volume of the selected object. The drawing can be exported and saved as a PDF file by using this command.
This command opens up an external reference palette and you can use it to attach DWG, PDF or images in your drawing as external references. This command allows us to edit the block and its parameters. This command will take the user to an exclusive block editor window where all the changes can be made and saved in the block. Call out or leaders can be placed in the drawing by using this command.
Using this command you can compare two versions of the same drawing and all the changes in it. Using this command you can record the repetitive actions in your drawing and replay them again to automate the entire process without having to write the macros.
Using this command you can share your drawing using a URL with the Autodesk cloud. The recipient can view the drawing without using AutoCAD software in a browser. Using this command you can show the history of a drawing and all the changes made to it. This command will work only when you save your drawing using a cloud service like Box, Dropbox or OneDrive.
You might be familiar with many of these commands but there are also many commands which are not frequently used despite their great features. This command extends the 2D object to the third axis which is the Z axis, so as to convert it into 3D. This command helps the user to create a 3D solid by revolving a 2D region around an axis. Using this command you can sweep a 2D geometry along a path. The following image shows an object created with sweep. This command will create a 3D box shape without using any 2D base sketch.
A 3D solid cylinder can be made using this command. Here the user has to provide the radius or diameter of the base and then provide the height of the object.
The user first has to provide the base dimension and then provide the height of the pyramid. Using this command you can join two or more 2D curves to make a lofted 3D object. In the following image red 2D curves were used to create this lofted 3D.
Using this command you can convert a surface into a 3D solid by adding thickness to it. Using this command you can convert 3D mesh and watertight objects made with surfaces to 3D solid and you can also control whether converted solid is smooth or faceted.
Using this command you can make a 3D wall-like shape as shown in the image here, you can also define height and thickness of this poly solid using command line options. This command was introduced in AutoCAD This system variable controls the behaviour or 2D curves when 3D tools like Extrude, Presspull and Sweep are used. You can change the value of this system variable so that AutoCAD either retains or deletes curves after converting them to 3D.
Using this command you can find the volume of a 3D solid as well as lots of other information like its moment of inertia, radius of gyration, centroid, and products of inertia. This command can be used to detect intersecting 3D solids.
The command is especially useful in situations where you want to detect clashes between different solids like pipes and walls. You can extract edges of a 3D solid as 2D geometries using this tool. In the image shown here the XEDGES tool has been used to extract the edges of the 3D solid and then the solid geometry has been moved to reveal the edges only.
For this stage, the following commands are sure to come in handy:. Fear not—the commands are not exclusive to 2D work! While our list is fairly comprehensive, should you wish to find more, Autodesk includes a full guide to shortcuts on their website. Close all open windows except for the one you are currently working on. Access the properties of the different objects within a drawing.
Repeat any command without having to press Enter each time Press Esc key to cancel. Open the options window contains the settings for AutoCAD. Access information such as the date you created a certain piece of work, or time spent editing a drawing.
Hide all objects in a drawing except the one you have selected. Produce a polygon you select the number of sides, from 3 to This command can be used to change the space of an object from model space to paper space and vice versa.
See the animated image shown below for reference. You can use this command to divide any 2D geometry into many equal parts. At each point of division, a point geometry will be added to the 2D curve.
If you need to rename any named object like layer, block or linetype simply use this command to rename it. More about this command can be found in this related article. This command can be used to break 2D geometries at one or two points. It is helpful if you want to break a curve at the point of intersection with another curve or if you want to create a gap by breaking a part of the geometry.
It can be used to find the distance between two points in the drawing. Using this command you can find a lot of information about your drawing like the date when the drawing was created and the total editing time consumed on the drawing.
This command can be used to make the selection from your drawing with filters. As an example, you can use quick select to make a selection set containing all circles of the drawing with the radius of a particular value.
