[英]Calculating thickness of 3D geometry of a model

I am doing finite element modelling.我正在做有限元建模。 I have a geometry which does not have a uniform thickness and I want to calculate the thickness of that in 4 distinct nodes and compare it with another model.我有一个没有均匀厚度的几何图形，我想计算 4 个不同节点的厚度并将其与另一个模型进行比较。 Is there any method to calculate the thickness of the 3D model?有什么方法可以计算3D模型的厚度吗？ (the 3D model can be exported in the format of .stl,.obj,.wrl,.feb.geo and some other formats ) （3D模型可以导出为.stl,.obj,.wrl,.feb.geo等格式）

Your best option is to import the mesh into a CAD package and take measurements directly from there.您最好的选择是将网格导入 CAD 包并直接从那里进行测量。

In the ANSYS world you can export the deflected mesh as an STL file and import it into SpaceClaim.在 ANSYS 世界中，您可以将偏转网格导出为 STL 文件并将其导入 SpaceClaim。 Then the CAD package can auto-patch the mesh to create a solid for further processing, or just use the measurements tools to get what you want.然后 CAD 软件包可以自动修补网格以创建实体以进行进一步处理，或者仅使用测量工具来获得您想要的。
