How to extrude a solid up to a mesh?

Hey, I have imported a file and I am trying to give it a floor and make it solid. I have converted the mesh to a solid and created a sketch of the floor. I would assume I would have to use project geometry to extrude up to the surface but I have yet to have any luck. Thank you in advance for your help.

Hi @domjonessa12 

 

I think it would be possible to extrude a cube and then split/cut that cube?

But my guess would be that Fusion 360 is not meant for working with dense mesh models.

Here is the original mesh.

Here is the solid file, but there are some issues with surface not being smooth enough. You could preprocess the file in Blender.

If I would be you, I would use other software for executing this task from the beginning, but perhaps you have your own workflow. 🙂

Can you explain what your overall goal is with this model?

The file contains hundreds of mesh bodies. Fusion 360 isn't the right software to deal with that many meshes.

Hello,

 

The intended goal of the project is to make a topography map with buildings and roads that could be 3D printed. I was able to get successful results in inventor using s mesh to solid plugin I no longer have access to. Granted that was with a much smaller mesh. People have suggested I try blended but the original mesh was in a 3dm file format and that is not compatible with blender.

Here is an image of previous attempt in inventor success.

 

The roads aren't really 3D dimensions in this. I was also attempting to use an outline of the roads that I could get from a DXF file and insert that into fusion model which was a struggle with such a large file.

 

Thank you for your time

The attached file has the solid body like you have in the image and all roads and building are hidden. If the roads are not visible, try raising them a little, so they are not on the same level as the solid mesh.

So, before you continue with any form of conversion, would it not make sense to first check basic dimensions?

This looks a little large to me 😉

If I am not mistaking then he has used cadmapper which provides real-life scale of cities, terrains, etc..

As we both mentioned earlier, I cannot really see how it is possible to work with this kind of a file within F360, but different people have different workflows, I guess. 🤔

Workflows aren't just different by coincidence 😉

Attached is the base terrain as a buttery smooth T-Spline.

In the browser you can see all the individual mesh bodies. I saved this one out to a .stl.

I then imported it into Blender and used Tris to Quads.

The resulting quad mesh I exported as a .obj, imported it into Fusion 360 and converted it into a T-Spline.

 

Depending on familiarity of tools and desired final output, there isn't necessarily a need to export this back into Fusion 360, once you have the mesh in Blender. But then, of course, to do everything in Blender you'd have to individually export all these mesh bodies, so it might in the end be easier to complete the project in Fusion 360.
