Coating / Insulation layer for a 3d bent busbar

Anonymous
Not applicable

Hello, 

I am trying to add a 2mm insulation layer to a 3d busbar that has bents in different 3d dimensions but I can find the tools that serve that purpose. 

I tried using the offset and the thicken command but I keep getting the error:

"The body could not be repaired after deleting faces ..."

 

The first image shows a sample of what I'm try to do and the second image shows the 3d bent busbar that I am trying to add insulation to. I imported the 3d bus bar as an .stl file.

You will get a better and more relevant answer if you attach the model you want to cover.  If you do not know how to attach your Fusion 360 follow these easy steps. Open the model in Fusion 360, select the File menu, then Export and save to your hard drive. Then use the Attachments section of a forum post to attach it.

STL is rubbish - doesn't it look poor quality to you too?

You will need native *.f3d geometry.

what I am really asking for is how to add the insulation layer not the quality of the drawing

Oh, in that case I will let someone else jump in here.

What @TheCADWhisperer is telling you is the the input geometry is garbage ( I completely agree) and that is the reason you cannot work with the normal Fusion 360 modeling tools.

Thank you guys @TheCADWhisperer and @TrippyLighting

The software I am using to produce the busbar is Ansys Maxwell. 

I can't export the f3d file from that software. The formats I can export are shown in the attached image. 

 

kindly advise

.STEP is the right format, assuming that thit actually does not export faceted geometry.

Thank you for the fast reply. 

How do I proceed after that? 

 

should I offset the faces by 0mm and then thicken them as new bodies ?

That could work, but let's get past eth export/import first 😉

I opened the exported .stp file in fusion 360 and tried to offset and thicken but still didn't work. 

attached is an image for reference

Export the .f3d file and attach it to the next post. It's getting late in this part of the world so I might look at it in the morning.

What is the ultimate goal of this exercise?

The ultimate goal is FEA thermal simulation in Ansys. 

So what I am doing now is adding insulation for the first busbar which is a winding in a medium voltage induction machine, then I will replicate over the other windings. After that, I will assign different materials and check the effect of each material on the performance of the machine.

My recommendation is to redesign the geometry with the native tools in Fusion 360. The input geometry is pretty terrible. even in STEP format. How was this created, to begin with?

This shape is automatically generated by an Ansys package called RMxprt. 

how easy is it to redesign it?

Is there an easy way to replicate the shape in fusion 360 ?

I have replicated the design in fusion 360 but can't figure out how to add the 2mm insulation.

Attached is the file. 

@TrippyLighting @TheCADWhisperer kindly advise
