Modify a simulation model

Commands in the Modify panel enable you modify geometry. These are the same commands found in the Design workspace, with a few exceptions.

To access the Modify commands:

1. Click (Simulation workspace > Setup tab > Simplify panel > Simplify).

Modification tools unique to the Simplify environment

The following commands are only available in the Simulation workspace > Simplify environment > Modify panel, and can be useful for preparing a Simulation Model:

• Remove Features: Used to quickly select commonly removed features such as chamfers, fillets, and small holes from specified bodies. The features are selected for removal automatically based on their relative size.
• Remove Face: Used to select a face; subsequent neighboring faces are removed to properly heal the geometry. Similar to selecting a face and using delete in the model workspace, but a chain selection is done automatically.
• Replace with Primitives: Used to replace a complex body, or group of bodies, with a single simple shape (box, sphere, or cylinder).

Modify tool	Used....
Remove Features	to simplify complex geometry by removing small, unnecessary features.
Remove Faces	to automatically remove relevant neighboring faces, when you choose a face to remove. This action ensures that the remaining geometry can be healed properly.
Replace with Primitives	to replace complex geometry with a representative primitive, such as a box, a cylinder, or a sphere.
Press Pull	to change the size of faces, bodies, fillets, chamfers, holes, and other geometry.
Fillet	to round sharp edges and corners.
Chamfer	to bevel edges.
Shell	to create a hollow cavity with walls of a specified thickness from a solid feature, by removing unnecessary material.
Draft	to add an angle to a planar face.
Scale	to increase or decrease the size of selected features, such as imported bodies that have no design history, or sketches, without having to alter dimensions.
Combine	to change the geometry of a 'target' body, to reflect the shape of selected 'tool' bodies using one of three Boolean operations, Join, Cut, or Intersect.
Replace Face	to replace an existing face with a new face that completely intersects the original body.
Trim	to remove unwanted portions of a surface.
Extend	to select an edge of a surface and extend it out further.
Stitch	to combine surfaces into a single surface or solid body.
Unstitch	to revert to multiple surfaces, or to break 3D bodies into multiple surface bodies.
Reverse Normal	to change the positive direction of the selected face, for example when repairing imported models.
Split	to divide faces or bodies, to add draft, delete an area, or create features. Split Face Divides faces on a surface, or solid. Split Body Divides a solid body into two. Silhouette Split Projects a profile from an existing part to split the target face or body.
Move/Copy	to move or copy a face, body, sketch curve, component, or sketch geometry.
Align	to move a body or component, relative to another object, without creating a relationship between the objects.
