Creating three-dimensional entities
progeCAD supports the following types of three-dimensional models:
- Wire-frame models, which consist of lines and curves that define the edges
of a three-dimensional entity. You can create a wire-frame model by drawing
lines, arcs, polylines, and other two-dimensional entities anywhere in three-dimensional
space. Wire-frame models have no surfaces; they always appear as outlines.
Because you must individually draw and position each entity that makes up
a wire-frame model, creating one can be exacting and time-consuming.
- Surface models, which consist of both edges and the surfaces between those
edges. You can create a surface model by applying elevation and thickness
to two-dimensional planar entities or by using specific three-dimensional
entity-creation commands. Surface models consist of individual planes forming
a faceted, polygonal mesh.
- 3D solids, which are three-dimensional ACIS entities that consist of faces
and edges. 3D solids appear to have volume and are easier to work with than
wire-frame and surface models. progeCAD supports viewing and limited editing
of 3D solids, including moving, rotating and scaling. Additionally, some versions
of progeCAD allow you to create and more completely edit 3D solids.
