Trouble converting an .igs file

[Brian]

I'm designing a cooling system and imported an electric fan as part of the project in an igs format. Trouble is that when I try to create the 2d drawing the fan does not display because it contains no solid bodies. How can I convert this to something that will display in the drawing? I would attach the igs but it's not a valid file type for an attachment here. I could possibly request it in a different format but thought I could use this type of knowledge for future projects.

Yeah, not having IGS as a format that this forum recognizes is a pain, I admit.  The easiest way is to create a zip file with just this file in it, then attach the zip file here.

Most likely, your model is made of surfaces, and they would need to be stitched into a watertight solid model using the Stitch command in the Patch workspace.  If you are able to attach your model, I'll take a look at it.

Good idea on the zip file. 

I attempted to stitch it together but things got a little out of my experience. 

File is attached

AHHHHHHH, I need to get this project finished and I cant figure it out! nooooooooo

I apologize for the delay, @Brian, I am in some internal training this week.

I took a look at your design.  Unfortunately, I do not have any great answers for you.  What you have are a very large number of unstitched surface bodies:

If I try to stitch them, there are open edges (shown in red by the stitch command), even with a large stitch tolerance (2mm), which is not recommended:

zooming in to some of these areas reveals the details.  For instance, zooming in on the embossed text, you can see where the open edges are.  Trying to repair these would be a very difficult task, IMO:

One question is where this model comes from.  It seems very low-precision.  Do you know what software was used to create this?   Do you have the original data?  Is it a watertight solid in that system?  You mentioned in an earlier post the possibility of extracting data in another format.  If the original data can be exported as a STEP solid body, Fusion should be able to read it as a solid.

Otherwise, you will have to try to repair this data.  I'm not even sure how to go about telling you how to do this, to be honest.  You can try to selectively extend and trim faces, or creating new surfaces using Patch or Loft in surface mode, but that will be painful at best.

I looked at this in Autodesk Inventor, and see the same results, so I think the problem lies in the original IGES data.

Sorry I don't have any better news for you.

I understand, the model come from the manufacturer and most of their models are step files. I suspected when I saw an igs I was in trouble. Thank you for taking time to look at this.
