DWG to 3D

[JFKANSAS]

So I have this DWG file with some 3d aspects. When I import to Fusion it is "hollow", kind of like a shell but it can't be thickened. Any way to fix this?

Can you attach the file here or send it to me? phil dot eichmiller at autodesk dot com

It sounds like you may need to do some work in the Patch environment to make this solid, but I can't tell for sure without the model.

Thanks!

[JFKANSAS]

Ya I can send later tongight or I can just add you to the project.

I tried some Patching, but I don't fully understand patching and when to use it. I kind of went through all the options looking for some tools. 

I believe this is from AutoCad, the import was fine, but that isn't the only place that has issues. 

Thanks.

[JFKANSAS]

I added you to the project.

Thanks.  There is a whole version, and a version I cut in half. The pictures are of the half which is what I need. 

[Phil.E]

The DWG file is translated into Fusion as some solid bodies and some patch bodies.

In your "half" model there are a bunch of Mesh bodies. You may have converted some Patch bodies into mesh bodies, or the source file had the mesh bodies in it. Either way, these are harder to work with.

So I opened up the full model and found a mix of Solid and Patch bodies. So I used Stitch command found in the Patch workspace. Just window select everything and set tolerance to 1mm. The result is far fewer patch bodies, and far more solids are formed.

Next I used the actual Patch command to cover the faces, and then stitch it all together. I did find some missing geometry, and a few places where the source geometry might need to be replaced entirely. Good luck! Let us know if you have more questions about this.

 

When you are done making solids, if you want it all to be one solid body, use the Model > Modify > Combine command.

Thanks,

When I try to stich, it says nothing is stiched.

I am trying to also import some svg files. In a 3d world the svg is being inserted into the document on the moon if the model is earth.... 

[Phil.E]

There could be lots of reasons nothing is stitched.

How far did you get with my workflow? It would help to know.

Tips:

1. Don't use the half model, it has mesh bodies which are not good for this workflow.

2. Use the Stitch tolerance setting, try very little tolerance and larger tolerance (0 to 4mm)

3. Make a video using Autodesk Screencast so I can see what you are doing, post the link here.

SVG:

If the SVG import geometry is very far from the origin, that means it was created this way. You either have to move it or go to the source software and create the SVG in such a way that it is not very far from the origin.

[JFKANSAS]

I actually deleted the half version and started over.

Whenever I try to stitch something it just errors and says nothing is
stitched. It doesn't matter what tolerance I try.

The SVG was created in illustrator so really just a blank page.

[Phil.E]

I'll try again in current production, but I cannot imagine Stitch has changed that much.

Assuming you want it to be one big solid, the workflow should be to first stitch that which will stitch, which was nearly all of it. After that, apply Patch bodies to the open faces to "cap" them, and stitch again. I was able to do enough of this on your model to determine it could be completed with more of the same manual fixing.

In Illustrator, just how big is the "blank page"? Illustrator definitely has the concept of size and position relative to a coordinate system. If you like send me the file.

[JFKANSAS]

Not sure if this will send. Please delete attachment from the site
after you have it.

it is 6" x 1". Illustrator is a 2d app so not sure where the extra
coordinate is coming from.

[Phil.E]

I did not find any illustrator file. Can you upload it to the Card Holder project?

Are you trying to say it's clearly a 3D file from AI? If the file is 2D it can still have a coordinate system. The geometry can still be far from the origin. I'll have to see when I can get the AI file.

For your stitching workflow, I opened the file and can see that you have done the first step. You have stitched everything that can be stitched. Now you have to move on to the next steps I showed you, which is adding Patch bodies and stitching until you have all solid bodies.

Here is your model with some step by step instructions.

Ok thanks for the help, things are looking pretty good. 

On the SVG front, it is the design that is the problem. The SVGs work fine when I tested them in a new document. 

For some reason the design doesn't have an origin so it seems to be lost in space. Is there any way to fix that? I even exported a STEP file and re uploaded seeing if it would change position but no luck.

[Phil.E]

The problem is that the component is very far from the origin. This came from the original file.

This video shows how to use point to point Move to return the component to the origin.

[JFKANSAS]

Thanks, I was trying something like that but didn't see the origin reset. Will try tonight to see if I can import svgs like I should be able to.

Thanks
