Problems with DXF / SVG extruding

Hi,  I'm struggling with this file. I created an svg (also tried dxf) and when i insert it some of the shapes appear as empty paths and won't extrude. I get an error message saying can't complete boolean operation. There may be overlapping paths but I can't figure out if there are in fusion.  I'm using this file to laser-cut corten steel sheet and I can't figure it out.  Here are a couple screenshots of when I insert the svg and also showing one of the shapes that doesn't "Fill" when I select all the shapes.  Any guidance will be appreciated.  Thanks,  Scott

Divide and Conquer, in this file, a temporary line fills both sides, good luck.

I saw 4 or five open regions, minuscule airgap, but impossible to find, 

 

Might help....

There is an app on the Fusion App Store called Fill Gaps.  Will find small gaps and either join or fill.  Useful for svg and dxf files that always seem to have gaps when imported into Fusion

It's a mess! I assume these are to be holes in a plate? What size is the plate itself and is it a simple rectangle? What program did you use to create the .SVG? Can you share the .svg?

Hi,

This will be a Sysiphus job.

Since direct processing with Divide & Conquer is very computationally intensive due to the numerous elements in the required representation of the profiles, the affected parts must first be projected into a new sketch.
You can then proceed according to this principle:
Some profiles then become profiles again when projected. For others, the gaps must be determined using the cross line method (divide et conquer).

the weird thing with this one is:  The profiles are all computed correctly (even though there are a LOT of them).  But, they don't get drawn.  If you select them, they will be selectable:

and, if I draw a rectangle around it, the entire inner profile is also fine:

so, I don't know why the profiles are not drawn, but you should be able to use them just fine.

I recognize these unclosed profiles:

Success in part...By saving your sketch 1 as a .dxf and then using the inbuilt Utility Bulk DXF Importer with a gap tolerance of 0.001" ( Ithink it was) worked mainly.Corten.jpg

 

I imagine you can sketch in new shapes to extrude cut as required.

With a few exceptions, this extrusion can be done using a Surface Patch/Thicken.  For the few areas that did not become a part of the original patch, a Surface Extrude/Split Body will take care of them.  I hope I did not miss any areas. Also the thickness desired was not specified, I used 0.25 inches.  Model is attached.
