    But apart from making these changes, there are also some default settings which can be changed using system variables to visibly enhance the performance of AutoCAD. In this article, I have listed fourteen such system variables. The Default value is set on 60 which will be suitable for most of the cases but if you want more speed you can change this variable to If there is only a single processor then this variable will not have any effect.

    There will be a slight acceleration when you are working with large drawings if you set this variable to 3. But you should not expect a drastic improvement in the performance just by changing this system variable.

    Make this variable 0 to increase speed when working with large drawings. The default value of this system variable is 0 but you change it as per your requirement. Redefine it? Overwrite it? When a prompt is suppressed by Expert option the prompt will automatically take your input as Yes. Maximum Performance 1 — For the Model tab and the last layout made current, the display list is saved to memory and regenerations are suppressed when you switch between the two tabs. For all other layouts, regenerations still occur when you switch to those tabs.

    For the remainder of the drawing session, the display list is saved to memory and regenerations are suppressed when you switch to those tabs. The default value is set to 1 which allows unnecessary regeneration in drawings thereby deteriorating performance. You can change this value to 0 to avoid any object selection preview thereby improving the performance of AutoCAD. System variable value 3 for the first circle and 0 for the second circle In the image above the value of the system variable was set to 3 for the first circle and 0 for the second one.

    You can turn this off by changing its system variable to 0 thereby enhancing the performance of AutoCAD. The default value of this system variable is 50 but you can increase the value of this system variable to speed up the drawing save operation. A Large value of this system variable will increase empty space in the drawing resulting in the larger drawing file.

    You can also decrease the value of this system variable or make it 0 to decrease the amount of empty space in the drawing but it will also increase the time taken in save operation. But decreasing the value of this system variable has its own advantages like it will improve compatibility of DWG files with other DWG compatible applications, it will reduce the size of DWG files due to less empty space and it will also avoid data loss caused by some antivirus programs that do not allow partial saves.

    The default value of this system variable is 0. The default value of this system variable is 1. You can change this system variable to 0 to stop highlighting objects when selected. Value of system variable set to 1 for the first circle and 0 for the second In the image above the value of HIGHLIGHT system variable was set to 1 in the first case whereas it was set to 0 in the second case.

    Excel and AutoCAD® – A match made in heaven (again!)

    In Listing This is used to position the box in WCS. BoxLength A positive value representing the length of the box. BoxWidth A positive value representing the width of the box. BoxHeight A positive value representing the height of the box.

    Exercise Figure Continuing with Exercise Enter the following statement into the skeleton Click event procedure for optBox: ThisDrawing. DrawBox 3. Follow the prompts in the command line to enter the position and dimensions required.

    Listing This will be used to determine the center of the box, which in turn defines the position for the box. Without this step, only the x and y dimensions are visible and the box looks no different from a 2D rectangle.

    Creating a Wedge The AddWedge method is used to create a Wedge solid, given the center of the sloping face and its dimensions in the x, y, and z directions. The center of the sloping face is the same as the center of the bounding box that encloses the wedge. The wedge is normally created with most of its edges parallel to the WCS axes.

    WedgeLength A positive value that represents the length of the wedge. WedgeWidth A positive value that represents the width of the wedge. WedgeHeight A positive value that represents the height of the wedge. In the next series of steps, you enter the DrawWedge macro and run it. This point is also the center of the bounding box for the Wedge object. Creating a Sphere The AddSphere method is used to create a Sphere solid, given its center and radius.

    SphereRadius A positive value representing the radius of the sphere. In the next series of steps, you enter the DrawSphere macro and run it.

    This point is also the center of the bounding box for this solid. Since ContourLinesPerSurface is a property of the Preferences object of ThisDrawing, all the solids in the active drawing will be updated to reflect any new setting.

    DrawBox 3.

    Where can I find a list of AutoCAD commands?

    Follow the prompts in the command line to enter the position and dimensions required. Listing This will be used to determine the center of the box, which in turn defines the position for the box. Without this step, only the x and y dimensions are visible and the box looks no different from a 2D rectangle.

    Creating a Wedge The AddWedge method is used to create a Wedge solid, given the center of the sloping face and its dimensions in the x, y, and z directions. The center of the sloping face is the same as the center of the bounding box that encloses the wedge.

    The wedge is normally created with most of its edges parallel to the WCS axes. WedgeLength A positive value that represents the length of the wedge. WedgeWidth A positive value that represents the width of the wedge. WedgeHeight A positive value that represents the height of the wedge. In the next series of steps, you enter the DrawWedge macro and run it.

    This point is also the center of the bounding box for the Wedge object. Meaning geometry, text and solid fills are each placed on separate layers accordingly. This is where AutoCAD makes some best guesses at reconstructing locations, object types and associations. This is because when a PDF is generated minor adjustments are made.

    For example, a straight horizontal line after being exported to PDF may not be exactly straight. When importing, AutoCAD has to decide is this line supposed to be exactly horizontal or should it be off by 0. AutoCAD conducts various inferences that occur in the background as you import a PDF, though it also offers optional inferences settings.

    Scaling and Cleaning an Imported Drawing Once you are happy with the configuration of the settings in the Import PDF dialogue, click the OK button: The PDF data should have now been placed in the model space, and at this stage, you may have probably noticed that your drawing is not the correct size: To fix this issue, use the scale feature of AutoCAD to resize your drawing.

    Select one side of the door opening or one end of a line if you are scaling based on the knowing length of a line : The next prompt will require you to enter a scale factor unless you choose to scale based upon a reference. As we want to scale using a known reference i.

    Do this by selecting an endpoint at the other end of the line i. In this case, the door opening now measures mm, and all of the other geometry has also been scaled accordingly: Now that your PDF has been imported and scaled to the right size you may want to check for anomalies and begin cleaning up any issues. Cycling through the various layers organised by object type may be a good place to start: References.
