Curve and Drawing Checks
When you click the Curve & Drawing tab in the Geometry CHECK (VDA standard) dialog box, a tabbed page appears. It contains the following checks:
• Distance from Itself—GeomIntegrityCHECK checks the proximity of the boundary-curve bounded surfaces to appurtenant surfaces. It reports the boundary curve if the curve extends beyond the parameter range of the surface.
• Self-Penetration—GeomIntegrityCHECK checks all bounded surfaces to ascertain whether or not, within the set tolerance, the face curve paths that form the boundary intersect themselves or whether face curve paths of a bounded surface interpenetrate or have contact with one another. Those that do are reported.
Self-penetrating curves:
Self-penetration has no design purpose. It is always an error. It causes problems with other geometrical operations, such as the generation of offsets or faces, as well as with NC programming.
Recommended solution:
Regenerate the curves correctly.
• IGES Conform Text—In drawings, GeomIntegrityCHECK reports text that does not conform to IGES fonts.
During the generation of text and dimensioning, special characters and mutated vowels (umlauts), as well as ß can lead to transfer problems. An excessively high number of text characters (>70 per line) as well as multi-line text can lead to loss during transfer and are for that reason to be avoided. Alternatively, a special agreement concerning the problem must be reached.
Recommended solution:
Replace special characters, umlauts, and ß (for example, ä with ae; ß with ss). Text with more than 70 characters must be divided into several shorter texts. Multi-line text must be replaced with several single-line texts.
After you have determined all the settings for the Curve & Drawing checks, click OK to start the checking process, or click Cancel to specify new settings.
