Fusion 360 exported STEP to Solidworks

Anonymous

I have someone that I’m attempting to make a couple models for in Fusion, and he uses solidworks 2017 (he is importing in as STEP files.)

He is giving me feedback that it is giving him errors in solidworks, and stating that some of the parts are not solids.

All geometry was made by Extrude in fusion.

Are some of the bodies not turning solid? And is there a way to check this?

What should I look in my workflow to eliminate his errors?

 

 

Attached is the Solidworks error he is getting.

Can you share one of these models ?

You can try to export in SAT format and see if that helps.

File>Export and then Attach the *.f3d file of these two components. (or at least one of them)

unfortunately i cannot post the file publicly at the moment.

I am not sure if that program posted above was Solidworks,

 

i do know this one is with the same model

 

apparently it is failing to load

(name is redacted)

Can you create a simple dummy file that exhibits the same behavior?

 

Does the SWx operator know how to run Import Diagnostics on the file?

Ive got one that gives invalid record index and wont load in solidworks.

 

 

I couldn't figure it out either.

I wonder if this is a Solid Works "thing".

I exported your example file in STEP format and it opened fine in ZW3D.

My instructions were to File>Export and then Attach your *.f3d file here.

 

I can verify that there is an issue opening exported STEP in SWx.

My first thought was delete the fasteners - but that locks up Fusion?

Why are your fasteners referenced by other features in the timeline?

 

So, then I simply hide them and exported again.  Still no go.

 

Therefore, I am going to have to go through the assembly component by component till I find the one that is causing the issue.  This could take some time. Bump this thread back to the top if I don't get back to you.

OK,

Many sketches unconstrained?

 

The issue is the white Wire 1.

I did not dig deep into the design, but why did you lengthen the wire with a second extrusion?

 

My preliminary findings.

Unconstrained sketches are always a first indicator that logical errors in modeling technique will follow.

Fasteners should not have other dependencies (and I would probably omit physical thread on fasteners and holes).

Second extrusion to lengthen an original extrusion (I don't understand this technique).

I see a Delete Face in the timeline, almost never used correctly by beginners.

If I dug deep - I would expect to find many issues.

 

It would be interesting to figure out why the Wire 1 is causing the issue since it is simple extrude, but I have to move on to other work.

 

If I export without wire 1 - then the STEP opens in SolidWorks.

I'm not sure if I recall the m doing that. I do recall using bodies as tool bodies to cut another part. I'm guessing fusion can't handle that?

The fasteners are imported from mcmaster carr with the threads in them.

I don't know whether there is a Fusion issue or a design strategy issue (I didn't dig that deep), but I did see enough questionable techniques in modeling that I would expect to resolve all issues if I started over from scratch.

 

The fasteners were probably modeled originally in SWx, so they should be OK, but why are there Timeline dependencies?  

 

I also noticed that the connector cable (or whatever it was called - I already deleted the file) was not modeled correctly.

 

Remove the Wire 1 and save as STEP.

In the future, while you learn Fusion techniques, you might save each individual part as a STEP to send to the SWx user rather than the entire assembly.  That way if one part fails - it is easy to solve.
