Modifying 3D Geometry

Thin/Surface:

– The Thin/Surface feature has two distinct applications:

Create thin solids (Thin).

Create simplified shelling (Surface).

– Selections available from Details:

Faces to Remove: Selected faces will be removed from their bodies.

Faces to Keep: Selected faces will be kept, while unselected faces are removed.

Bodies Only: The operation will be performed on the selected bodies without removing any faces.

– When converting solids into thin solids or surfaces, you can specify a model's thickness in one of three offset directions:

1. Inward

2. Outward

3. Mid-Plane

Thin/Surface details:

Using the simple block shown here, let’s look at basic Thin/Surface behavior.

Notes on Thin/Surface:

– The Thin/Surface feature supports thickness > 0 if the selected faces are part of surface bodies.

– This allows for the “thickening” of an imported surface.

Mid Plane Option:

– This does not mean mid-plane extraction.

– Bodies will be hollowed, such that the inner and outer walls of the bodies are offset equal distances from the original faces.

– Example :

Fixed Radius Blend:

– The Fixed-Radius feature allows you to create blends on model edges.

– You can select or pre-select 3D edges and/or faces for blending.

Face selection applies blend to all the edges from that face.

– When pre-selecting, additional options are available from a RMB context menu

(face edge loop selection, smooth 3D edge chain)

– You can edit the blend radius in the Detail View. Clicking Generate completes the feature creation and updates the model.

Variable Radius Blend (same as above plus):

– Use the Detail View to change the start and end blend radius for each edge.

Also, the Detail View can set the transition between blends to smooth or linear. Clicking Generate completes the feature creation and updates the model.

Vertex Blend: allows surface or line body blending.

– Vertex must belong to surface or line body.

– Must connect to exactly 2 edges.

– Geometry surrounding vertex must be planar.

Chamfer:

– The Chamfer feature allows you to create planar transitions (or chamfer face) across model edges.

You can select or pre-select 3D edges and/or faces for chamfering.

If a face is selected, all the edges from that face are chamfered.

– When pre-selecting, additional options are available from a right mouse button context menu (face edge loop selection, smooth 3D edge chain)

Every edge on a face has a direction. This direction defines a right and left side.

– Chamfer is defined either by two distances from the edge for the planar transition (chamfer face), or by a distance (left or right) and an angle.

– The type of chamfer is set up in the Detail View along with the distances and angle.
