The Export IGES (3D only) command exports 3D curves, surfaces, and solids from a Vectorworks file into IGES format (version 5.3). Closed solids are exported as solids, while open solids are exported as a collection of surfaces.
Objects that are exported to an .igs file include:
|
● 3D loci |
● 3D polygons |
● Architectural objects (wall/slab/column/stair) |
|
● Chamfers |
● NURBS curves and surfaces |
● CSG solids (add/subtract/intersect/section) |
|
● Fillets |
● Groups |
● Extrudes and multiple extrudes |
|
● Parametric objects |
● Shells |
● Solids (sphere/cone/hemisphere) |
|
● Sweeps |
● 3D Symbols |
|
To export an IGES file:
Select File > Export > Export IGES (3D only).
The Export Options dialog box opens.
Select Export Solid as Trimmed Surfaces to export a solid as several different “bodies” (for example, a cube exports as six bodies); otherwise, a solid is exported as a single body.
Click Export.
Specify the export file name and destination, and then click Save.
