The Compare to CAD thickness colormap processing can be very time-consuming when working with a large mesh.
You can create a thickness colormap of a Mesh data object in comparison to a CAD model. In this case, from the Mesh Operator dialog box (Insert | Mesh | Thickness Colormap), select the Compare to CAD check box.
When you select CAD faces for a Thickness Colormap compared to CAD, PC-DMIS uses both sides of the material to compute the thickness; however, PC-DMIS only colors the data for the selected faces.
PC-DMIS computes the deviation of the data object thickness in comparison to a CAD model.
The software colormaps the Mesh data object used for the comparison to CAD to show the deviations.
To do this:
From the Mesh Operator dialog box, select ThicknessColormap from the Operator list.
Choose the corresponding Mesh data object.
From the Method list, select the method: Ray Based or Sphere. For details on these methods, see "Mesh Thickness Colormap Method".
Type the Max Thickness. The software does not evaluate any data value greater than this value.
Type the Max Angle value. This is the maximum angle between the ray that pierces the mesh and the normal at the pierced point.
Select the Compare to CAD check box and enter the Max distance. PC-DMIS uses the data within this distance from the CAD model for the colormap.
Type the appropriate tolerance values in the Plus Tol and Minus Tol boxes. You must use a minus sign when you type a negative number.
Click Apply.
Create annotations. For details on how to create annotation points for the Mesh Thickness Colormap operator, see "Thickness Colormap Annotations".
Click Create.
