Inherit mesh model to surface model

Rectangular building model created with other mesh modeling softwareofConvert to surface modelYou must to do something before you go on. 

For example, Rhinoceros-likeIf you want to take over to solid modeling with 3D CAD softwareorIf you want to extend to parametric modeling in Grasshopperis. 

If you want to convert a curved mesh to a curved surface model,previous articleplease look at.

 

Rectangular mesh ⇒ Surface is easy!

This time, I would like to convert the following simple rectangular mesh model created with Blender to a surface model with Rhinoceros. 

objand then imported into Rhinoceros. 

MeshToNURBconverted to a surface model. 

Since the original mesh overlaps, select the original mesh with SelMesh and delete it. 

I don't have much opportunity to do solid modeling, but from Blender's mesh modelingExtending Grasshopper to Parametric ModelingI use this procedure. 

By the way, even if it is not a solid model, you can cut it cleanly with ClipPlane as a mesh model.. even if it's not a solid modelclosed meshIt seems to be okay if it is recognized as If you just want to cut a cross-section and turn it into a drawing, it doesn't seem necessary to convert it to a surface model.
