BricsCAD Journey – Part 23: 3D Solid Entities

Welcome back to our tour of BricsCAD Pro! Today’s focus is on 3D solid entities. They’re flexible, powerful,  and the foundation for more advanced 3D modeling functionality including assemblies, sheet metal, and BIM.

You’ll find the most popular solid modeling tools on the Model tab of the Quad. And, they’re all available from the Model menu.

Solid Primitives

BricsCAD enables you to create solid primitive shapes.

Solid Primitives

While solid primitives may resemble mesh primitives, solids are considerably different than meshes. They’re solid, not hollow, and include mass properties. And, solids are supported by a comprehensive set of design and editing tools in BricsCAD as well as the Sheet Metal and BIM add-on applications.

Even if you start with basic solid primitives, such as the boxes and wedges below, they can be combined and edited to produce realistic models.

More Solid Shapes

In addition to primitives, BricsCAD provides tools to create solids in virtually any shape.

Polysolid

Creating solids with the Polysolid tool is like drawing polylines except it creates 3D solids instead of 2D polylines. One of the most common uses of Polysolid is to draw 3D walls.

Polysolid walls

The POLYSOLID command includes multiple options enabling you to specify height, width, and justification. You can create a combination of line and arc segments and you can choose whether the segments are joined together or separate entities.

Polysolid with arcs

Another option allows you to create a polysolid along a selected path using the specified width and height.

Extrude

The Extrude tool allows you to extrude a profile along a path. You can use it instead of Polysolid if you want a profile that’s not limited to a rectangle. Neither the Polysolid or Extrude tools require you to select a path.

Solid extrude

Additional options enable you to extrude straight out from the profile and even taper the extrusion.

Sweep

The Sweep tool requires you to select a profile and path. An Alignment option enables you to automatically sweep the profile perpendicular to the path even if you draw them on the same plane.  Additional options, for Basepoint and Twist, offer flexibility that’s unavailable with Extrude or Polysolid.

Solid Sweep

Revolve

Use the Revolve tool to revolve a profile around a specified axis. The Mode option enables you to create either a surface or a solid.  Additional options offer flexibility to specify the axis of revolution and the angle of revolution.

Loft

Use the Loft tool create a solid that passes through multiple profiles. The sequence in which you select the profiles determines the primary shape. In the following image, the same profiles are selected in different orders. Additional options allow you to select guides and specify settings that control the smoothness and shape of the loft as it passes through the profiles.

What’s Next?

In this post, I shared just a few examples of the 3D solid shapes you can create in BricsCAD. But, that’s only the beginning. You can combine, subtract, slice and edit solids in many ways to create realistic and complex models. During the next few stops on our BricsCAD Journey, I’ll introduce you to some of my favorite solid editing tools!

Looking Back

If you missed the previous tours on our BricsCAD Journey, it’s never too late to catch up! First, learn about functionality in the BricsCAD Classic Edition. Then, continue on to the Pro Edition. Everything you learn about Classic also applies to Pro!
