3. Geometry CreationClick Action-Create12Click Mode-Geometry3Click Entity-Volume123Geometry PrimitivesCreated centered at originUse transformations to position
4. Geometry BooleansClick Action-Boolean12Click Mode-Geometry3Click Entity-VolumePerform Boolean operations between volumes Subtract UnionIntersect123
5. Bottom-Up Geometry CreationStart by defining verticesConnect them with curvesCreate a surface from a loop of curvesCreate a volume from a closed set of surfaces1234
6. Web Cutting1231Mode - Geometry2Entity-Volume3Action-WebcutMany different options for web-cuttingEach brings up a separate command panelWeb-cutting slices through your geometry creating additional volumesWeb-cutting is most often used to enable sweeping
7. Web CuttingPlane from vertices:Coordinate plane:Cylindrical surface:Plane normal to curve:Result:Example Webcuts
8. Virtual GeometryComposite Operation: Combines surfaces together Mesh is not constrained to intermediate curvesUsed to improve mesh qualityDoes not change the CAD model

12. HealingTranslating geometry into the ACIS format can be often problematicPro/E is less accurate than ACIS if you use the default tolerancesGaps, overlaps, and internal inconsistencies are commonThe ACIS Healing Husk may fix many problemsClick Action-Modify12Click Mode-Geometry3Click Entity-Volume1234Choose Heal from the dropdown menuAnalyzeAutoHealLists problems with the selected volumesAttempts to fix the problems4
