Hi all, Im struggling to flatten surfaces in auto cad for Mac.

Im not sure if I need a plug in for this (if so can anyone recommend one please) or I'm doing something  wrong.also I'm drawing a slide for a helter skelter in isometric how can I work the shapes for this swell as the angled its falling.

if any one can help it will be much appreciated hope this makes sense.

 

thank you.

Hi @pauljj1977 ,

 

It's not entirely clear from your question what you want to do.
If you need to get a flat projection, then you can use the FLATTEN command, which is destructive to 3D object

or FLATSHOT command which simply creates 2D projection while leaving the 3D objects untouched.

 

Can you share screenshot or drawing itself with additional comments?

Isometric drafting, as most of us understand is, is NOT 3D and not a "surface": it is already "flat" and "2D" and most likely all line /arc objects that have no relationship to each other except where you might have stopped and started LINE and ARC commands

Perhaps that is the core issue you are facing?

>>>>> im trying to flatten this to get the out side shape as it will have a cuved face.

 

Do you need to unfold this surface?

If yes, then it is impossible in AutoCAD for Mac and there is no plugins for Mac version for such task.

Yes I was, I thought that was the case. I will have to find a software to run a side with autocad for this. Do you have any ideas?

That's just two spline or Pline curves and drawn single line elements, correct?

I use one of such applications - Unfolder.

But you need additional step - convert DWG created in AutoCAD to OBJ file. You can try to use one of the online converters.

@pauljj1977 ,

 

I also tried to unfold your 3d object with Rhino.

You can find the result in the attachment.
