Draft Accuracy of Geometry

You can refine the faceting of the part, where the rectangular and triangular faces formed by the facet lines are used to make the contours as close to the actual object as possible.

The program will first facet the volume with a value that it assumes appropriate. This can be refined if needed. The starting point for faceting when creating a face is the default value of the face's portions, based on which the program will create the default faceting.

You can achieve the exact shape of the face (A) by reducing the tolerance value (B) and the angle tolerance value. The angle tolerance affects the mesh formed by triangular faces on rounded surfaces. If you decrease the angle tolerance value, the number of triangles increases and the shape of the surface becomes more detailed.

When cutting up a volume, the program will again facet the volume with a calculated value that it assumes appropriate (default faceting), even if you have refined the faceting.

Find an appropriate draft accuracy by trying out several different values.

1. On the tab, in the Settings group, click Draft Accuracy.

   If you select the function in the assembly model, you can select parts or all of the parts by selecting Confirm.

   Note: In an assembly model, the draft accuracy affects only the local parts. Specify the draft accuracy using the tolerance value.
2. Define the Part´s facet data in the dialog box.
   • Enter a value, in the Tolerance field.

     Refine the draft accuracy by reducing the tolerance value, for example to 0.1 or 0.01. If you wish to have a coarser draft accuracy, increase the tolerance value, for example to 1 or 10.

   • Enter the value Angle tolerance in the field, and select OK.

     Refine the shape of a rounded surface by reducing the tolerance value, for example to 0.1 or 0.01.

     If you wish a rounded surface to have a coarser shape increase the tolerance value, for example to 1 or 10.

   • The program calculates default faceting when you set both Tolerance and Angle Tolerance to 0.
3. Select OK.
