Shape description is a collection of surface and solid modeling, analysis, and 2d and 3D sketch commands that enable you to design parts that are aesthetically pleasing, and include more complex geometric requirements that extend beyond simple prismatic shapes.
Shape description provides:
- Ability to create quality curves that can satisfy certain aesthetic conditions.
- Realistic previews before creation and editing.
- Feature commands such as Sculpt that work on a wide range of geometry in a surface or mixed surface and solid environment.
- Commands to examine the qualitative and quantitative measurements of the surface geometry, such as consistent wall thickness and curvature of surface geometry.
- Ability to maintain certain continuity requirements at surface boundaries.
- Model browsers that clearly identify feature relationships.
Use the Sculpt command to add and remove material from an existing solid body, or to create a new solid body based on untrimmed surface geometry.
You can select surfaces and work planes as bounding geometry for the sculpt operation. In addition, Sculpt implicitly uses existing faces of solids to designate possible boundaries. Sculpt cannot fill or add material in infinite space, which means the surfaces, together with any pre-existing part, must create a closed, water-tight region.
Tips for shape description operations
- Change appearances on key surfaces to distinguish them from others while sculpting.
- Unlike split and stitch operations, surfaces used for sculpting need not be trimmed to share common edges. Also, surfaces are not required to fully overlap other surfaces that define the boundary.
- By default, sculpt features consume input surface features such as stitched, extruded, or revolved surfaces. Consumed features are nested and indented below the consumer to show the dependency on that feature. You can right-click in the browser, and then select Consume Inputs to change the consumption status.
