Import Data into TrueGrid®
TrueGrid® imports data from three sources: CAD/CAM, polygon data, and pre-existing meshes. You can also import your TrueGrid® command session files.
CAD/CAM and Solids Models
|
Complete models are faithfully imported from your favorite CAD/CAM or Solids Modeler, ready to use. This means that the geometry may not fit together perfectly. There is no need to repair the geometry before importing it into TrueGrid®. TrueGrid® imports trimmed surfaces and other geometry, in the standard IGES format. The model to the left was built using a commercial CAD system and imported into TrueGrid® as 24 surfaces. |
Polygon Data
To import polygon data into TrueGrid®, the data has to be formatted into two files. Below is an example of these files.
Example of the nodal file format:
1, -3.383404, -0.583990 , 2.585073
2, -3.187954, -0.598938 , 2.572747
3, -3.186691, -0.594553 , 2.575749
4, -3.383906, -0.579564 , 2.587889
5, 4.597703, -0.602771 , 2.579074
...
Example of the element connectivity file format:
hood 7306 7302 7249 7244
body 7121 7125 7129 7116
body 7124 7307 7247 7130
hood 7301 7298 7253 7250
hood 7297 7294 7257 7254
...
STL Files
Stereolythography, or STL, files can be read into TrueGrid®. There is a standard format for STL data and it can be read in either ASCII or Binary. Find out more about STL. Find out more about how to get surface data for biological geometry.
