Need help with fitment and joining/combining two objects!

Anonymous
Not applicable

Hello!I made a spoiler for a car, but the fitment doesn't match the trunk. I'm a complete newbie to this, so I would love to get some assistance, because I don't know how to make it so the spoiler sits smoothly on the trunk without colliding with it! Here's a pic of how it looks, and I added my project below as well for anyone interested in helping! Any tips or help is highly appreciated!

This looks like the same 3D model you posted yesterday and it isn't exactly a beginner project.

 

My advise would be the same. Model the spoiler in box-view mode and change to smooth-view mode for checking. You have very many self-intersecting polygons in that model so it is unlikely going to convert into a solid body or surface body.

 

You are aware that your timeline is turned off because you are working on an imported model ?

That isn't necessarily a bad thing f you are working with T-Splines only (in that case it can actually be quite helpful)  but if you are starting to work with surfaces and/or the tools in the Model environment you might want to consider turning the timeline on.

 

There are several ways this can be "matched". You can convert the trunk mesh to a T-Spline and then into a surface body or solid body. Then, if you spoiler is a solid body you can combine-cut the trunk and the spoiler.

 

The mesh you downloaded was modeled in a Sub-D mesh modeling software such as Modo, Maya, 3DS Max, Blender etc. This mesh is not the original mesh o the Sub-D control cage it is the already subdivided mesh. That means the original mesh has already be subdivided in the originating software likely using catmul-clark subdivision (or open subdiv).

 

That mesh/model you imported into Fusion 360. Because it is a quad mesh (no triangles) it can be converted not a T-Spline and then into a solid body or surface body. These sort of meshes are almost always modeled for visual representation, so they are not closed (water tight) so they convert into a surface body.

 

You can now model your spoiler and then, after you have modeled the T-Spline convert the spoiler into a solid body and use the trunk surface to split that solid body. The split surface then will match the trunk perfectly.
