Using model simplification

When using Model Simplification to import CAD models, it should be expected that the import process takes longer time due to the processing needed for simplification. The processing time is highly variable depending on the model properties and so on, but can be expected to take around ten times longer than importing the fully detailed model through MultiCAD.

However, there will typically be a significant improvement in add-to-drawlist time, clashing, creation of drawing views and other operations that involve processing of the imported geometry. Again the improvement will be variable depending on model properties, simplification settings and so on, but can often give ten times or more performance improvement, and this factor often increases as models get larger as can be seen in the second image displayed below.

Note:
Results from Model Simplification may vary. Models that are badly connected or pre-simplified will usually not give as much improvement as others. Some models containing a lot of open bodies may not give any significant performance improvement at all. Refer to the recommendations detailed in Control over model creation or export from source tool on how to obtain models most suitable for simplification.

The following are example screenshots from a model suitable for simplification where the performance can be significantly improved without affecting the visual fidelity too much.
