Run Time Collision Detection

In CADmep, when you enabled the Run Time Collision Detection feature, model collisions, also referred to as clashes, are automatically highlighted in the model. The command can also be run manually at any time.

To use the Run Time Collision Detection feature:

1. Click Database Takeoff CAD Settings Collision Checks tab.
2. Set the following options on the Collision Checks tab:

   • Enable Run Time Collision Detection: Make sure this option is enabled (selected) to use the run time collision detection feature.

     Show Clash in Viewer: When this option is enabled, when a collision is detected, the collision is immediately displayed in a viewer dialog (window). You should only disable this option if you want the collision to be marked on the screen (in the drawing area and not in a separate pop-up viewer window) using a circle whose color is specified by the "Clash Marker Color" option.

     Clash Marker Color: You can leave this set to its default color, or choose a different color.

     Marker Screen Size: This specifies the size of the circle (marker) as a percentage of the display screen size. In many scenarios, leaving this option set to its default is sufficient.

     Design Line Collision Checks: When this option is enabled, the Run Time Collision Detection feature is activated (on) when filling in 3D with Design Line. If you do not want to use this feature when filling in 3D using Design Line, then disable this option. For this example procedure, leave this option disabled (unchecked).

3. Click OK to save changes on the Collision Checks tab, then close the Database dialog.

   Now that the Run Tim Collision Checks feature has been enabled, clashes or collisions in the model will be automatically highlighted by displaying a circle (clash marker), of the color specified in the Clash Mark Color option, at the clash location.

   Note: The clash marker (circle) is not a typical AutoCAD entity, but rather a simple graphical visual indicator. It cannot be deleted using typical AutoCAD commands. To remove a clash marker, you must resolve the collision, and run the check command again. Edit the collision objects by double-clicking on the circles, or use the REBUILDALL command. Using the Check command will highlight any remaining collisions.

   In the example shown below, the green circle is the visual indicator (clash marker) showing the location of the collision in the model.

   

4. To remove the clash markers, you must first resolve the collision, then type in the CHECK command at the command line to run the collision detection again on your model.

   When the collision is resolved, running the CHECK command again removes the visual indicator.
