5.4. Solid Overview

Solid is the final geometry type of the CAD modeling. It's usually a closed shape which contains lots of faces which stitch together. Solid tools are available on the Solid toolbar. You can create or modify solid by these methods:

Box

From a coordinate system and define the length and width, or create by two points.

Cylinder

From a coordinate system and define the radius, start/end angle, and start/end height, or create by specifying bottom, top center.

Cone

From a coordinate system, and define the top/bottom radius, start/end angle and start/end height, or create by specifying bottom, top center and radius.

Sphere

From a coordinate system, and define the radius and u/v start/end angles, or create by select center point and another point on sphere or define the radius.

Torus

From a coordinate system and define the path and profile radius, and other three angles parameters.

Extrude

Given a face as profile, an axis as direction, it linearly extrudes to a solid.

Revolve

Given a face as profile, an axis as rotational direction, it rotates to a solid.

Sweep

Given a face as profile, an edge or wire as path curve, it sweeps to a solid.

Loft

Give a set of closed edges or wires, it loft a solid. The two ends of the curves group can be replace by point. Such as you can create a cone solid by loft a circle and a point.

Fillet

Fillet creates a rounded internal or external face on the part. You can fillet all edges of a face, selected sets of faces, selected edges, or edge loops.

Chamfer

The chamfer tool creates a beveled feature on selected edges, faces.

Draft

Draft tapers faces using a specified angle to selected faces in the model. One application is to make a molded part easier to remove from the mold. You can insert a draft in an existing part or draft while extruding a feature. You can apply draft to solid or surface models.

Thicken

Creates a solid feature by thickening one or more adjacent surfaces.

Wedge

Wedge tool support to build wedges, that is, boxes with inclined faces.

Boolean

Boolean operation contains cut, common, and fuse two solid shapes.

Prism

Create prism, pyramid or draft shape by side number, side length, height and other parameters.

Combine

Given two profiles and two extrusion direction, it will calculate the boolean-intersection solid shape.

Fillet creates a rounded internal or external face on the shell or solid shape. You can fillet all edges of a face, selected sets of faces, selected edges, or edge loops.

To open fillet: Click Fillet (Solid toolbar) or click Geometry, Solid, Fillet.

Recommendations for Fillets:

In general, it is best to follow these rules when making fillets:

  • Add larger fillets before smaller ones. When several fillets converge at a vertex, create the larger fillets first.

  • Add drafts before fillets. If you are creating a molded or cast part with many filleted edges and drafted surfaces, in most cases you should add the draft features before the fillets.

  • Save cosmetic fillets for last. Try to add cosmetic fillets after most other geometry is in place. If you add them earlier, it takes longer to rebuild the part.

  • To enable a part to rebuild more rapidly, use a single Fillet operation to treat several edges that require equal radius fillets. However, if you change the radius of that fillet, all the fillets created in the same operation change.

To make a fillet operation,

  1. Select fillet type: equal radius or various radius.

  2. Select edges or faces from a shell or a solid.

b. constant radius fillet
