Working with geometries

What you’ll learn

• Creating geometries: Create a model using geometry elements.
• Modifying geometries: Use simple operations and boolean operations to modify your model.

Geometry editing in Quanscient Allsolve is done in the Geometry section. The Geometry elements list is at the top of the Navigation panel (left sidebar). Geometric Entities are in the Common sidebar on the right.

Geometry section overview - geometry elements on the left and geometric entities on the right.

Geometry elements

All shapes, imports and operations are referred to commonly as Geometry elements.

• Import
  • Import file - Import CAD or mesh files
    • .step .iges .brep .gds .msh .nas
• Shapes
  • Sphere
  • Box
  • Cylinder
  • Torus
  • Cone
  • Surface rectangle - Useful for defining port surfaces
• Simple operations
  • Remove - Remove volumes.
  • Translate - Move selected volume or create copies.
  • Rotate - Rotate selected volume around an axis or create rotated copies.
  • Grid - Copy a volume along one or more axes to form a grid.
• Boolean operations
  • Fragment all - Run automatic Fragments operation on all volumes against all.
    • There is always an implicit Fragment all operation as the last operation, to prevent any overlapping volumes.
  • Intersection - Portion common to both volume sets is kept.
  • Union - Merge all selected volumes/surfaces.
  • Difference - Subtracts volume set 2 from volume set 1.
  • Fragments - Split overlapping volumes into new, non-overlapping volumes.

Building elements

To add elements:

1. If geometry editing is inactive, select Edit model.
2. Select + next to Geometry elements.
3. Select a shape or operation.
4. Adjust element properties/settings.
5. Save your settings.
6. Reorder if necessary and build the elements.
7. Select Confirm model changes to finalize. The model is updated and entity tags are locked.

New elements are added by selecting + next to Geometry elements

Element ordering

Geometry elements work as a stack where each new element is built on top of previous ones. The list ordering goes from top to bottom - the newest element is always at the bottom of the list.

Translate and rotate: copying

The translate and rotate operations support copying. Enable copying in the operation settings and set the number of copies to create. Each copy is translated or rotated by the specified amount relative to the original.

Original box	Translate with 5 copies	Rotate with 3 copies
It's just a box.	6 boxes in total - 5 copies and the original	The row of boxes is rotated around a point and copied 3 times

Grid

Use the grid operation to create a 2- or 3-dimensional grid from the selected volume/volumes. The grid operation can also copy a volume along a single axis, just like the translate operation.
