Trying to create a tool cavity with surface body

[Richard_bagg]

Hi all.

I have a closed surface model (it's a car shape, completely in blender) that's Imported as a solid looking part in Fusion.

In a section view the STL is as I knew, Hollywood. The model is sealed as stitching and hearing Show no error.

I want to create a negative of this hollow volume in a tool block. 

I extrude a new body over the shape but cannot find how to remove the full volume from the block.

I used to do this all the time in Solidworks and Creo. But Fusion doesn't seem to like the Hollywood volume.

Any advice would be great please.

Because it’s STL, Will presume you have not converted to Fusion body type.

Create the block, (New Body) and the convert it (tesselate) to STL in position.

Mesh Modify commends will then allow Boolean operation to cut the car from the block, as far as I know.

Might help…..

Can you share that model in the original Blender format?

If this was properly Sub-D modeled in Blender, it should be a quad mesh and not be exported as a .stl file.

It was an OBJ file i modified in blender (to seal up the myriad of gaps) and then exported to STL/Fusion

Here are the models.

1 is the blender file and 1 is the Fusion file where i have gotten too.

Basically its the James Bond Lotus submarine. I want a solid model so i can modify it as a solid and break it apart for 3D printing (and add mechanical features like motors etc)

I don't seem to have permission to download the file(s). Please zip and attach the file directly to a post.
