Data transfer from CAD files | Generating STL files with 3D mesh (option152)
12.2 Generating STL files with 3D mesh
(option152)
Application
With the 3D mesh function, you generate STL files from 3-D models.
This allows you to repair defective files of fixtures and tool holders,
for example, or to position STL files generated from the simulation
for another machining operation.
Requirement
Software option152, CAD Model Optimizer
Description of function
When you select the 3D mesh icon, the control changes to 3D mesh
mode. The control covers the 3D model displayed in CAD-Viewer
with a mesh of triangles.
The control simplifies the original model and removes errors, e.g.
small holes in a solid or self-intersections of a surface.
You can save the result and use it for various control functions, e.g.
as a workpiece blank with the BLK FORM FILE function.
The simplified model or parts of it may be smaller or larger than
the original model. The result depends on the quality of the original
model and the selected settings in 3D mesh mode.
The Sidebar window shows the following information:
Option Meaning
Original
triangles
Number of triangles in the original model
Number of
triangles:
Number of triangles with active settings in the
simplified model
If this option is highlighted in green, the
number of triangles is in the optimum
range.
You can further reduce the number of
triangles using the available functions.
