OVERKILL not removing all overlapped lines

Anonymous — Wed, 24 Jun 2015 11:24:34 GMT

I have a dxf file that i have exported from Adobe Illustrator.

When i open in AutoCAD 2016, explode & use the OVERKILL command to remove overlaps it is not removing all the overlaps. On first attempt it removed quite a few but when picking some entities and deleting there is still another line undernieth.

I have tried the OVERKILL with different tolerances and different settings with no success.

any ideas?

I have attached the dxf file in 2010 format

Thanks

There is no attachment. In the mean time :maybe the issue is Z-coordinates? Try the FLATTEN command.

I'm thinking there's inconsistencies in the drawing. Color, thinkness, linetype, etc. It could be one of many causing the command to not catch them all.

I have checked all of the 'ignore object properties' in the Overkill options box so i dont see how those should come into play.

However, i made sure those properties are the same on all entities. Check the Z heights and there is no difference.

I have re attached the DXF file

Your drawing is very busy and full of very small objects, are you actually trying to achieve something else perhaps? FLATTEN took forever to work on it here, so it was not flat on a single plane I suspect.

I think that overkill is failing on the splines. and the overlaying splines are not the same direction rather than a Z elevation or planar issue:

SPLINE Layer: "0"
Space: Model space
Handle = 16cf9
Length: 19.9830
Order: 4
Properties: Planar, Non-Rational, Non-Periodic
Parametric Range: Start 1.0000
End 2.0000
Number of control points: 4
Control Points: X = 402.2533 , Y = 258.1111 , Z = 0.0000
X = 394.3179 , Y = 257.9433 , Z = 0.0000
X = 389.9418 , Y = 261.3348 , Z = 0.0000
X = 391.5026 , Y = 270.6632 , Z = 0.0000

I recall OVERKILL has issues when PEDITACCEPT = 1, try setting PEDITACCEPT = 0 and running OVERKILL again.

I would use FLATTEN for converting SPLINE to POLYLINE. Then EXPLODE, OVERKILL, OVERKILL with higher tolerances, and JOIN, MPEDIT with ADD and EXTEND with some tolerance. This helps a little, but not nearly good.
Then hatch with SOLID individually selecting a point inside (without associativity, annotativity, with higher tolerance, big zoom). Usually it works acceptably fast. Some objects, however, are very bad and must be resolved manually (in my cutout that was only one).
And then HATCHGENERATEBOUNDARY.
Overall, it could take 2-3 hours.

It takes forever with the OP's file, that's for sure.

Re: OVERKILL not removing all overlapped lines

ВeekeeCZ — Thu, 02 Jul 2015 22:20:23 GMT

OVERKILL TOLERANCE 5, POINT HATCH, HATCHREGENERATEBOUNDARY, FLATTEN, JOIN.

About 35 min.... aint that bad... on my newish i5 laptop.

If you have attached any image in the drawing overkill will not work. Try creating a new file and crtl-copy the elements you are interested to, and PASTEORIG these entities. Execute the OVERKILL command in the new file (it will work) and copy back with PASTEORIG in the old file. You may lose some dimension alineations.

I'm having a similar issue but using AutoCAD LT 2021. Have lots of overlapping splines mostly pairs in opposite directions. Flatten is not a command in LT; however, I have a script that we call "Flatten" that removes z values, but doesn't seem to help here. Looks like Edit Spline works but only on one-at-a-time, which is prohibitive.

Help! Thanks!!!

Re: OVERKILL not removing all overlapped lines

Your posted files contains blocks with splines in them: OVERKILL will go inside blocks to do this for you.
PLUS everything in your file is pretty much at Z=0. Rotate the UCS view to FRONT and see for yourself.

Did you post the wrong file or are you trying to solve a different problem? What challenge is this file for you?

@pendean Thanks so much for looking at this right away! That was original file from architect that we're working with in LT. I've attached our working file. I exploded the blocks but overkill misses/ignores the splines...

Re: OVERKILL not removing all overlapped lines

pendean — Tue, 23 Feb 2021 21:13:21 GMT

Dumb questions:

1)why did you feel the need to explode their block in the first place? It appears they went to a lot of effort to make it work.
2) And when you did for whatever reason, why did you feel you need to explode all four (identical) instead of just one then copy it over 3-more times? You now have a nightmare of 33Thousand+ splines ready to create havoc in your file.
3) everything in that drawing is still flat, Z=0: see for yourself, rotate the view to FRONT or SIDE.
what problem are you facing exactly?

Not dumb, but good questions.

1)why did you feel the need to explode their block in the first place? It appears they went to a lot of effort to make it work. >> Didn't know that overkill works within blocks. May have gone to alot of effort, but they have literally duplicated all of it.
2) And when you did for whatever reason, why did you feel you need to explode all four (identical) instead of just one then copy it over 3-more times? You now have a nightmare of 33Thousand+ splines ready to create havoc in your file. >> I get that it would have been best to work with one block then replace the others, but the problem isn't file size or number of elements - my computer processes the overkill command in a minute or so.
3) everything in that drawing is still flat, Z=0: see for yourself, rotate the view to FRONT or SIDE.
what problem are you facing exactly? >> I ran our flatten script to ensure z=0. I only mention flatten as that was pointed out above that it could be the problem.

WHY I'm in need of removing the dupes is because this is intended to be a CNC cut pattern in sheet metal and my vendor and their software will not be able to work with it.

Thanks!

You can convert them using PEDIT Multiple to curves (which would line-segment them), EXPLODE and OVERKILL.

But... imho the real solution (only for full acad) would be to write a custom routine that will do that.

scottMHX4E — Wed, 24 Feb 2021 11:54:10 GMT

Thanks. That only works on spline at a time, right? Hence the script?

That’s not something I’ve got the experience or time to do.

At this point I’ll need to go back to source and see if they can fix.

Re: OVERKILL not removing all overlapped lines

ВeekeeCZ — Wed, 24 Feb 2021 12:14:29 GMT

Can't confirm if there is some sort of limitation in LT but full acad supports multiple selection.

PEDIT/MULTIPLE See HERE

But sending it back to the source if possible is what I would do.

Just FYI (I know, LT) attached why I've suggested using FLATTEN instead of PEDIT.
