Imported DXF file containing irregular circles has thousands of lines and points rather than just complete circles

[asteffel]

Hi everyone,

Firstly, thankyou for taking the time to look at my post. I am a total newbie to F360 and only use it on the odd occasion so please forgive my ignorance and lack of terminology.

I have imported a DXF file of a series of irregular shaped circles into my design and want to modify the pattern to suit, but each circle has a huge amount of lines and points instead of just 1 complete line. How do I make each circle into a simple whole shape which contains just 1 line? TIA

Can you share the .dxf? And how was it created?

[asteffel]

Thanks for replying.

I'm not too sure how it was created. I've included the DXF file (as a .zip) hope it goes through.

I had a close look, those are not circles, and I hazard a guess there is not supposed to be any circles.

Closed loop is the best description.

Fusion is not really the software for this type of sketch.

What is the planned output you want from inputting this to Fusion?

[Warmingup1953]

Yes file is usable but as others have noted these are not Circles.  

You could "build on top of this"as a template?

So the end result I'm wanting (if I understand your question correctly) is to create a new design based off this current one by utilizing its "closed loop" shapes. Basicly, I was after an easier method to draw 500-ish circular shapes that is loosely based off this design rather than painfully drawing each individual one.

How do you mean "use as a template"? I was hoping the imported file would offer an easy solution to draw a hole heap of circular shapes by just copying and pasting them (or similar) into my design. Do you think that is possible?

[Warmingup1953]

I use software to cut on my CNC router that can identify and drill a centre hole in each irregular shape but that won't help you! No sorry I can't see any way other than re-sketching based loosely on this pattern that you have found visually appealing. I don't think the CAM workspace in Fusion 360 has similar but others here may know.

[asteffel]

Ok, thanks. Hopefully someone can help me here.

2 point circles will be pretty speedy.

[asteffel]

Yeah thanks Warmingup1953, but it can't be actual circles.

[Warmingup1953]

Ok, final tilt at the Windmill....Could this work? 476 I think it is Bodies?

[asteffel]

That's looking closer to what is needed. Is there a way to "reverse" the extrusion to isolate a 2D pattern?

[Warmingup1953]

Yes I imagine so.  But the big issue is the large number items...Exactly what are you attempting? and can it be done just with the file as is?

Thanks for your help and time spent Warmingup1953😀. What I have done is, painfully drawn up half of the shapes and mirrored that to make up the rest🙄. "That'll do pig... That'll do" - Babe 🤣
