Purpose

This tool help users to know the Polygon Budget of the symbols in the drawing and also indicate the symbols that might cause possible performance issues due to missing Level of Details (LODs).

Workflow

1. Place the symbols that you wish to be tested into the drawing and open the 'Model Performance' dialog.

   

   If you have added or removed symbols from the drawing, click on the 'Update' button on the right-side bar to update the list in the Model Performance dialog.

   Clicking on 'Clear' will remove all symbols from the drawing and the Model Performance dialog.

   

    

2. The Model Performance dialog will be updated with the information of the symbols in the drawing. Each tab within the dialog displays the different information regarding the symbol's graphics.

   Polygon Budget

   This table shows the actual polygon count for each of the symbol's Level of Details (LOD) against the polygon budget.

   • Green - Actual is lower than Budget
   • Yellow - Actual is slightly higher than Budget
   • Red - Actual is a lot higher than Budget
   • Black - Actual is extremely high than Budget (also means that no LODs are available)

   When the actual polygon count is higher than the budget, this could jeopardize the performance of CET when used in a drawing.

   

   Missing LOD

   This table highlight the symbols that has the same polygon count for the different LODs, indicating that the same model is used for all LOD levels and therefore will affect the performance of the symbol in CET.

   

   Detailed Mask

   This table shows the symbols that do not have a specific model for each LOD level. This will also cause a performance issue as the graphics engine will attempt to switch between the identical models.

   

    

3. You can then navigate to the symbol by double clicking on the symbol's name under the 'Snapper' column, which will bring the 2D and 3D view to the selected symbol.

   

   You can also have the symbols selected in the drawing and check the 'Show Selection Only' option in the Model Performance dialog. This will update the dialog to only display the information of the selected symbols in the drawing. 

   

    

4. The results can then be exported to an Excel sheet from the 'Excel Export' tab.

   

   • Drawing -> Excel - Export the information of all symbols currently in the drawing
   • All component tabs -> Excel - Export the information of all symbols from all visible component tabs
   • cm3D -> Excel - Export the information of all cm3D models in a specified folder directory
   • cmSym -> Excel - Export the information of all cmSym models in a specified folder directory

   Below is an example on how the exported file looks like.
