Are there any tips to reduce the file size of a part I have created in Exact Surfacing?

If you have a part that is large (for example the model is 30 MB and you need it to be around 3 to 5 MB), there are a few things that you can do to reduce the weight of the model:


1. In the Exact Surfaces tab, use Adaptive for fitting surfaces in Surfaces>Fit Surfaces



Select Adaptive:



Selecting Adaptive will optimize the number of control points thus reducing the number of patches.


2. Reduce the number of Grids (resolution) in Exact Surfaces>Grids>Construct Grids:



Reducing the number of Grids will decrease the size of the model.


3) Try saving the file as a .stp file. Sometimes, but not always, the .stp files may be smaller.


4) Evaluate your part to determine if the part is more organic and or more mechanical in nature. If the part is more mechanical in nature, it may be a candidate for surfacing in the Parametric Surfaces module. For our example above, if the part has around 1500 faces, Parametric Surface modeling could reduce it to around 100-150 faces. This reduces the file size by an order of 10 bringing the original file from 30MB to 3MB.




VERSION 11

If you have a part that is large (for example is 30 MB and you need it to be around 3 to 5 MB), there are a few things that you can do to reduce the weight of the model.


1) In the Shape module, when you select to NURBS>Fit Surfaces



Select Adaptive:


.


Selecting Adaptive will optimize the number of control points thus reducing the number of patches.


2) Also reducing the number of Grids (Resolution):



The Grids>Construct Grids command will decrease the size of the model.



You could also try saving out the file as a .stp file. Sometimes, but not always, the .stp files may be smaller.


3) Evaluate your part to determine if the part is more organic and or more mechanical in nature. If the part is more mechanical in nature, it may be a candidate for surfacing in the Fashion module. For our example above, if the part has around 1500 faces, Fashion could reduce it to around 100-150 faces reducing the file size by an order of 10 bringing the original file from 30MB to 3MB.
