Boolean Operations (3-D)

3-D Standard > Process > Add

If problems occur with Boolean operations, you should bear the following in mind:

  1. On the Information tab, you can select 3-D, Further > Rebuild . This also makes sense before creating an offset. Sometimes,selecting Information > 3-D, Further > Rebuild > Data structure check, 3-D geometry > Entire drawing, Min-Max check, or 3-D Standard > Tools > Surface > Further > Optimise part may help as well.
  2. Example: You want to union two parts which do not touch. It then frequently makes sense to lengthen both parts so that they intersect. It is then easier for the CAD program to union the two parts. The intersection is deleted again during union.
  3. In the feature log, change the sequence of processing steps that lay before the Boolean operation. Then, perform the Boolean operations again by means of a feature recalculation.
  4. If you are unioning more than two parts, first union the parts that are in contact with or intersect each other with their entire surfaces. Union the parts that only touch each other on lines, rather than surfaces, last.
  5. In very rare cases, the component is drawn many millions of mm away from the absolute origin. This leads to the "consumption" of a large number of integer places during internal saving of the absolute coordinates. Fewer significant decimal places are available as a result. In this case, you should move the component nearer to the absolute origin. However, this is only necessary if a component is extremely far away from the absolute origin.
    Tip: Before using Information, 3-D point coordinates to determine the absolute coordinates of the part you need to delete all processing planes, as the coordinates in respect of the active processing plane will otherwise be displayed, instead of those in respect of the absolute origin of the world coordinate system.
