Surface Modeling & Mesh Editing Flashcards

Which Autodesk tool converts a T-Spline body into a BRep (boundary representation) solid or surface?

Answer: Convert command in the Surface tab

The Convert command in the Surface tab converts a T-Spline body to a BRep solid or surface for use with traditional modeling tools.

When editing a mesh body in Fusion 360, what does the 'Reduce' command accomplish?

Answer: Decreases polygon count while preserving overall shape

The Reduce command decreases the polygon count of a mesh body while attempting to preserve the overall shape and silhouette.

In surface modeling, what is the purpose of a 'Patch' surface?

Answer: To fill a hole or gap in an existing surface

The Patch command fills holes or gaps in surfaces, creating a new surface that closes the open boundary.

What continuity condition ensures that two surfaces share the same tangent plane along their shared edge?

Answer: G1 (Tangent)

G1 tangent continuity means two surfaces meet and share the same tangent plane, eliminating visible crease but not necessarily matching curvature.

Which mesh editing operation in Fusion 360 allows you to push and pull mesh faces directly in the Mesh workspace?

Answer: Edit Form

Edit Form in the Mesh workspace lets you directly push, pull, and manipulate mesh faces, edges, and vertices.

When creating a surface with the 'Loft' command using guide rails, what is the primary function of the rail curves?

Answer: Control the direction and shape between profiles

Rail curves in a Loft guide the shape and direction of the surface as it transitions between the cross-sectional profile curves.

What does the 'Unstitch' command do to a stitched surface body?

Answer: Separates stitched surfaces back into individual face bodies

Unstitch separates a stitched quilt (surface body) back into its individual constituent surface faces.
