Apply COLORMAP to a CAD model with Multiple Surface Profile Tolerances

There are two methods to apply a Surface Colormap when the CAD model has multiple surface-profile tolerances.

Method 1

Create multiple Surface Colormaps, one for each tolerance or Surface Profile.

To create multiple Surface Colormaps, do the following:

1. From the Pointcloud toolbar, select the Pointcloud Surface Colormap button (). The Pointcloud Operator dialog box for the Surface Colormap appears.

2. Enter the tolerances.

3. Select the specific CAD surfaces. For details on selecting CAD surfaces, see "Working with CAD Surfaces" in the "Scanning Your Part" chapter in the PC-DMIS Core documentation.

4. Click Apply to apply the Surface Colormap to the selected CAD surface.

5. Click Create to add the Surface Colormap in the Edit window.

6. Create a second Surface Colormap in the same manner for the next Surface Profile.

Method 2

You can create groups of selected CAD surfaces within a single colormap. Each group can have different tolerances and Surface Colormap parameters (Refine factor, Max distance, and Thickness). If the Surface Colormap has two or more groups, the software displays the color scale with percentages.

Examples:

To create groups and apply different tolerances to the selected CAD surfaces within one colormap, do the following:

1. From the Pointcloud toolbar, select the Pointcloud Surface Colormap button (). The Pointcloud Operator dialog box for the Surface Colormap appears.

2. Enter the tolerance values and colormap parameters (Refine factor, Max distance, and other parameters).

3. From the Pointcloud Operator dialog box, select the Select check box in the CAD Controls area.

4. Click each of the CAD surfaces to be grouped. The surfaces highlight with the group color as you click them. Click the Deselect button to remove the last highlighted surface from the group.

5. To group the selected (highlighted) surfaces, click the Add a new data group (+) button located to the right of the Group list.

This group remains the active group until a new group is created. Any changes made to tolerances or COLORMAP parameters are applied to the active group. Also, if you select additional surfaces, they are added to the active group.

To identify which surface belongs to which group, the selected CAD surfaces are highlighted with the group color. To identify which group a grouped surface belongs to, press and hold the Shift key and then left-click the surface. The Group list updates to show the group to which it's assigned.

If you click a CAD surface that is not in the active group, it is removed from the group it is currently assigned to, and it is added to the active group.

6. To create another group, click the Add a new data group (+) button again, click the surfaces on the CAD, and update the tolerances and any COLORMAP parameters as necessary. Repeat to create more groups.

7. To make changes to a group, select it from the Group list and make the necessary changes.

8. To delete a group, select it from the Group list and click the Remove the current data group (-) button.

When a COLORMAP contains two or more groups with different tolerances, the color scale is automatically set to show the deviations with percentages.

Dimensioning Surface Profile using Pointcloud Colormap with Groups

You can use Pointcloud COLORMAP Groups to dimension Surface Profiles.

1. Create the Pointcloud COLORMAP Groups as described in Method 2.

2. For legacy dimensions, do this:

Click the Profile Surface Dimension option from the Dimension toolbar (View | Toolbars | Dimension). The software displays the Surface Profile dialog box for legacy dimensions:

For XactMeasure dimensions, do this:

Ensure that the Use Legacy Dimensions option (Insert | Dimension | Use Legacy Dimensions) is not marked.

Click the Profile Surface Dimension option from the Dimension toolbar. The software displays the XactMeasure GD&T - Surface Profile Dimension dialog box:

Click the + sign to the left of the COPFCOLORMAP in the Features list to show any COLORMAP groups.

3. Select the desired COLORMAP groups and features to dimension from the Features list. If you select a datum feature, it must be a plane.

4. Set the other options as needed.
