Object will not export; staying in two sections.

opesey — Mon, 25 Nov 2024 03:39:39 GMT

Hello all,

I am having difficulty exporting a finalized part. I have checked all surfaces and components of the drawing that meet one another. I am getting two distinct groups when I got to unionize the part. Having these groups is a causing the part to be unable to export into an STL. Any help is appreciated and frankly, I have no idea how to fix it even if a solution is posted. Moving or resizing parts causes voids within the cylinders.

I have tried numerous times to redraw the part with all solid components but after unionizing the part, all components become hollow.

Any help is appreciated. At this point, I would really like to understand why, if we could hope in a discord or something while a fix is being made, I would love to understand what I am doing wrong for future parts. I can happily compensate for the time as well. Attached is the drawing.

Cheers!

@opesey In AutoCAD, exporting to STL requires all of your objrcts to be 100% 3DSolids or Watertight Meshes.

You have none at all and you got the same error message I did at the commandline, yes?

I will only respond to this thread to negate any confusion. I am not in any class, just doing this as a hobby.

When extruding, do I need to use a different command to make them all solids and not surfaces, that seems to be the underlying issue here with things not wanting to export.

Is this how you are doing it

https://help.autodesk.com/view/ACD/2025/ENU/?guid=GUID-B3B99AC4-B137-4144-A5ED-A8167906172D

That page has many links to additional instructions too.

Your surface model has many holes that keep it from yielding a solid model via the surfsculpt command. I capped some of the holes (red and green objects in the image below) but more needs to be done.

I think you should use extrude or sweep to create solids. If the object outline object you use to extrude is a closed shape it can be used to create solids.

Yes, using that method. All parts remain solid until the union command, after that, it seems to hollow out most items.

Union command? How was that used and on what?

it was used on the whole drawing after i complete it, to essentially make the whole drawing "one piece"
