Mesh to object

[Anonymous]

After I insert a mesh stl. and hit convert to object a warning comes up saying it has like 5,000 triangles and the program is going to run slow. I've tired seeing if it would work and every time it it locks up and I have to restart the program. I understand it's a complex object but is there a way to make it less complex or another way to turn my stl objects into objects on this program?

When you convert the STL file which is composed of three sided facets into a BRep (Boundary Representation) each of those facets is turned into a separate face.  Both the conversion time and subsequently the processing of each of the faces is very computationally intensive which is why we provide the warning.  Actually we set a limit of 10,000 facets after which we automatically stop the conversion process because the results are not practical to use.  We hope to offer ways to utilize these mesh models in the future (see this posting) but for now you will need to reduce the number of facets in the STL.

My recommendation for the best and freely available package for reducing the mesh would be Meshmixer which you can download here.  There is always compromise in the reduction of a mesh between maintaining the complexity of the model and reducing the number of facets.  

If you would like to share images or the model we can try to help you with the process.

What would you like to do with your imported stl mesh object?  That is, what operations would you like to perform on it?

The Convert command will try to convert a mesh to a surface or solid body, but it does it by turning each mesh triangle into an individual face on the body.  The conversion can be very slow, and the resulting performance can also be slow.  That's why that warning comes up.

The other operation that you can do with a mesh body today in Fusion is create a new Sculpt body that approximates it.  Using the Pull command or the Object Snap mode in some Sculpt commands, you can create a Sculpt (TSpline) body that fits to your mesh.  This will work if the mesh is a smooth shape, it won't work so well if the mesh has a lot of sharp corners.

I will put together a screencast this morning showing how to use Pull to create a Sculpt body to conform to a mesh.  More later...

This is a link where I get all the stl objects that I am trying to put into fusion 360.

Thanks for the help

I just want to be able to print all of these objects from the website in the coment above

And I have used the pull command when I created the exhaust cone, but I was concerned I was missing minor detail, And I didn't know how it would work when creating the compressors.

Editing meshes is a significantly different process than generating models in Fusion.  If there are existing meshes that you want to make adjustments to then it might be better to use Meshmixer and modify the mesh.  Certainly using Thingaverse models would work better this way.  If there are just portions of the model you want to modify it may be better to generate a new model to your requirements in Fusion and then Save as STL which will create an STL file that can be 3D printed.  Here is an example of how the cone can be modified in Meshmixer.  As I mentioned earlier mesh modeling is an area we hope to provide in Fusion in the future.

I have created some flat, one sided objects in Sketchup which  can export as STL files. Now I would like to project the outline of those files (which I imported as mesh bodies) onto a sketch. How would I do that?

Here's a quick screencast showing how to convert a mesh into BREP so that you may use the project to sketch tool.

Hope that helps!
