Import DataDoctor (IDD)
|
|
This new and improved module enables you to import and utilize data from other systems more effectively. The toolset has been expanded to provide more ways to find and heal problems that prevent a model from solidifying. |
This tutorial will use the tools in the New Import DataDoctor to repair a STEP file that has gaps, holes, and extra surfaces.
1. Set Working Directory to IDD
2. Open 
and set the Type to All Files (*) and double-click the idd_tutorial.stp file.
3. Select OK button from the Import New Model. Close the information window that appears.
4. Ensure that the model is being shown in Wireframe 
.

|
Notice that there are multiple edges that are yellow vs. purple. This denotes one-sided edges and they need to be repaired to make this part a solid. |
5. RMB CLICK on the Import Feature from the Model Tree and select Edit Definition.
6. Select the Import DataDoctor ... 
icon in the right-hand toolbar.
There are 3 modes available:
 |
Repair Mode |
In Repair mode, you can remove gaps and sliver surfaces, add uv-curves, and fix tangency in the imported geometry. |
|---|---|---|
|
|
Modify Mode |
In Modify mode, you can modify individual curves and surfaces, replace one-sided edges with a uv-curve, and change surface math properties using tools and procedures such as merge, intersect, and so on. |
|
|
Featurize Mode |
Featurize mode is the default mode when you import a model into Pro/ENGINEER. In this mode, you can convert individual surfaces or group of surfaces and quilts to analytical, spline, or procedural surfaces or quilts. You can also use surface conversion tools such as convert to plane, convert to cylinder, and so on to convert surfaces. |
IDD Display Toolbar
The tools on the IDD Display Toolbar are the commonly used tools in IDD.

7. Note the new Model Tree tab - it is the GTS Tree (Geometry and Topology Structure) and is similar to the standard Pro/ENGINEER Model Tree except it shows the Topology of the geometry you are attempting to repair.
8. Click 
from the Model tree > Expand All or > Collapse All to expand or collapse all branches respectively.
Removing Coincident Surfaces
On the GTS Tree, you can see the imported model and the logical grouping of surfaces under Component 251. However, Surface 242, lies outside the group and is not required in the model as it is a coincident surface, that is, this surface lies on top of another surface. Surface 242 can, therefore, be removed.

The ID numbers for your imported model may be different. |
9. On the GTS Tree, RMB on Component 251 and click Hide. Component 251 and its surfaces are temporarily hidden in the graphics window.
10. Select Component 251 on the GTS Tree. The model appears in the graphics window as a red mesh. Surfaces that appear as a red mesh as shown in the following figure indicate that they are hidden.
11. Select Surface 242 on the GTS Tree. Notice that it is and extra surface that does not belong to Component 251.
12. On the GTS Tree, right-click Surface 242 and click Delete on the shortcut menu.
13. On the GTS Tree, RMB on Component 251 and click UnHide.
