Cut body with mesh shape.

[o0harz0o]

Hello everybody,

This is my first post here so I'll try to explain myself as much good as I can. I'M totally noob with fusion 360 (have been doing some designs lately and checking youtube tutorials by myself, so far my projects are becoming alive).

My situation is the next one:

I got an STL file wich for simplifiying I plane cutted it with Meshmixer. Imported the cutted STL file into Fusion 360 and converted from mesh to brep (traking consideration of the maximun triangles that Fusion can convert). So far so good I managed to convert it.

Now, I have a body that I wouild like to extrude only to fit this mesh shape. That way, the mesh will lead the shape of my extruded body from bottom to top (I'm attaching images to make it clearer).

My problem is that I can't find any information on how to do this. All I want is my Fusion 360 body with the shape of my mesh on top of it. (The STL file will sit on top of my body, it is an stand for the object).

At the moment, I have projected the shape of the converted mesh to create a body with the same sizes as the mesh (x/y axis).

Any help from you, experts, would be much appreciated.

Thanks in advance,

Edit: Just thinking, if there is anyway to make the mesh to brep single faced (just one face to extrude) maybe I would be able to extude my body with extend type to object?

 There are multiple ways to combine the two.  Attach the file to reduce guessing games (File/Export/Archive file *.f3d).

Hello,

First, let me thank you for your answer and interest.

Here you have the .f3d file as requested.

Thanks in advance,

This should be close to what you described.  If you want the sides to be perpendicular to the base, then create a sketch on the bottom and project the top of the base to the sketch.   You'll need to make sure the projected geometry forms a closed boundary.  If there are any white circles in the boundary, use the Coincident constraint on them.  Once the projected geometry has a closed boundary, draw a circle (or a rectangle) around the base.  Use that to Extrude/Cut the base and you will have perpendicular sides on most of the base.

Hello Etfrench,

Lovely demostration, exactly what I was looking for. Thanks a lot.

Now, I've found another problem: When triying to make the walls perpendicular to the base (it has to be a straight stand) followed your instructions. Projected the top of it to a sketch and after that draw a big elipse to extrude/cut. After a lot of CPU proccesing this error message appears.

Would you mind to indicate me if im doing something wrong?

Thanks again!
