IGES Export Options
You can set the export options when you export SolidWorks part or assembly
documents as IGES files.
The IGES translator supports layers when you export an assembly document
as an IGES file. You must set the Surface
representation/System preference export option to MASTERCAM.
The assembly components in the IGES file appear on layers that you can
turn on and off in Mastercam®, or in other applications.
To set the IGES export options:
Click File,
Save As.
Select IGES (*.igs)
for Save as type, then click Options.
Select from the options described below, then
click OK.
Click Save
to export the document.
Solid/Surface features
Output as
IGES solid/surface
entities. Exports the data
as solid or surface entities. Select Trimmed
Surface (type 144) to convert the faces of the part, assembly,
or the selected surfaces to trimmed surfaces in the IGES file. Select
Manifold Solid B-rep Object (type 186)
to export boundary representation (BREP) data to the IGES file.
IGES Wireframe
(3D curves). Converts the solid body to a 3D wireframe representation
in the IGES file. Unlike surfaces or faces, you cannot export individually
selected model edges to an IGES file. Select either B-Splines
(Entity type 126) or Parametric
Splines (Entity type 112) depending on the entity types required
by the target system. For more information, see the
table.
If you select both of the above options, the model is exported
as both trimmed surfaces and 3D curves.
When you export
an assembly as separate files in ALIAS IGES, the origin in the part files
is at the coordinates of the assembly origin.
Export 3D Curve features. Includes
3D curve features in the exported file.
Export sketch entities. Includes
sketch entities in the exported file. All 2D and 3D sketch entities are
included.
Use high trim curve accuracy.
Exports using high trim curve accuracy; the file size is larger than if
the check box is cleared. This setting affects files exported both with
Trimmed surfaces and with 3D curves. High trim curve accuracy
can sometimes help if the target system has trouble importing the IGES
file, or cannot knit the surfaces into a useful solid.
IGES assembly structure
Save all components
of an assembly in one file (assemblies only). Saves all assembly
components, sub-assemblies, and sub-assembly components in one file. Otherwise,
the assembly components and the sub-assembly components are saved as individual
IGES files in the same directory.
Flatten assembly
hierarchy (assemblies only). Flattens the assembly to one level
of only part bodies. A flattened file contains a top-level assembly and
a series of parts that contain imported features.
Output coordinate system. Select
a coordinate system to apply for export. If you select --
default --, no transformation matrix is applied.
