[Plugin] Hole Punching Tool

@dave r said:
I get the same results as UncleX. Curious.
It is odd as there should be no connection...
I have reproduced it too...
HolePunch does add some observers to Definitions and any new definition that is added.
Perhaps it's clashing with the way ShapeBender adds its new shape-bender component definition ?I am investigating...

Here is an updated version http://forums.sketchucation.com/viewtopic.php?p=271170#p271170
1.7 20100121 Observers are now first removed then added to avoid duplication and rare clashes with other scripts.******It appears that the way ShapeBender copies/adds component-instances/definitions and also uses 'make_unique' etc fell foul of the HolePunch definitions observers: a definition could occasionally get two of the same HolePunch observers added which really messed everything up big time!
In this updated version the HolePunch definitions observer 'removes' the definition observer before 'adding' it to avoid having more than one of that observer attached to the same thing [usually it's not already there, but the .remove_observer() only returns true/false on success/failure so if it's not there to remove it doesn't cause a problem with the following code].
I've retested this with ShapeBender and now I haven't managed a glitch let alone a BugSplat [yet].
Please try it and report back...

Thank U
the bug is solved. -

Yep, Shape Bender now works just fine, and Fredo Scale bend also, btw.
One other thing to report though:
( I have the same problem with one face cutting compos.) If a component has some geometry outward of the cutting plane, like a overhanging sill for instance, no cutting or punching anymore. I noticed that the reglue option stays available even after having selected it to apply.
Strange thing is that if a flush installed component has a part pulled out, all already installed instances stay punched. Not the ones installed thereafter.

Can you post am example SKP.
I get no problems with cutting compo's that project outwards ?
I need to see its cutting plane etc...
EDIT: I have managed to find a compo' with a protection face that didn't punch consistently.
I fixed it thus: place the component on a wall.
Edit it, Select All, Intersect with Model.
Place new instances of the compo' and they will Punch Holes consistently... -

Done that. Got a little better but not quite it yet: some weird "parasites" after Punch.
Model joined; Frame is simply made of a box, Offset on a face and PushPull to make opening.

Your wall had its back-face reversed which didn't help.
Also there were some stray lines inside the Component [Xray mode to erase them].
BUT most importantly - a punching component needs a loop of continuous edges to form the punching template: when you introduced a 'sill' it made two interrupted loops of edges... The fix is to inset the bottom/ends of the sill ~1mm so that the 'frame' still keeps its continuous loop and punches properly. You'll never notice that the sill isn't exactly aligned...
See this image and updated SKP

Hey thanks. I will try that.
One precision though. I forgot to say that the reversed back and the stray lines appeared after asking to punch. Before that it was a brand new file with brand new wall and frame, no mess up.
edit;
So the loop must be made out of uninterrupted segments. No other line can butt to any one segment.
Offsetting the sill sides is not practical, kills the Punch time saving. So I made the sill a group and it works. Hiding the "seam" lines helps making the frame and sill look as a whole.
Hoping the script can be further enhanced to manage colinear lines on the cutting loop.

Worrying about inset windows, made me further investigate and find the easy way to do any frames. Make the whole frame a group (so it can have any shape, protrusions, insets) then make the loop at the wall face position, select everything an make component. Punches very well.

Here's v1.8 http://forums.sketchucation.com/viewtopic.php?p=271170#p271170
Algorithm improved to find the Cutting-Component's 'cutting-loop[s]' vertices - to use for the matching with Punched-hole - this avoids glitches if multiple edges in the Z=0 plane - like projecting sill parts etc etc...
[
Mariocha - not need to fiddle with the geometry now...] -
Wow ! I knew you could do it. !!

I have completely recast the algorithm to work out the cutting >> punching 'hole[s]' edges - I thinks it's quicker AND now it should always 'punch' a hole the same shape as the 'cut' hole...
-
Nice !
The edges of the cutting loop are still needed, right ?
-
The cutting-component needs its cutting-edges defining, so that SUp knows what part of the cut-face to hide.
The hole punching simply mimics that set of cutting-edges, ignoring unneeded internal edges - just as SUp does when cutting... -
Hot on the heels...
here's v1.9 http://forums.sketchucation.com/viewtopic.php?p=271170#p271170
The Context-menu code has been completely recast to avoid exacerbating the 'grayed-out items issue', that can occur when too many tools load/unload in/out of it. Now the tool only 'loads' once and it enables/disables its items depending on the selection - e.g. you always get 'Set Depth' enabled, you only get 'Punch' enabled [i.e. not grayed-out] if the selection contains suitable Component[s] and so on...

Glad I donated.
But this new version makes things clearer to me.
I'd say there are 2 purposes for this pluging;
1-Punch holes in parts, like metal punching i.e. the case where compo shape = hole shape
2-Punch holes in walls, like for window openings i.e. where in some cases, the compo shape does not = hole shape.
Like in the case of a window in a wooden wall, the sill comes with the frame and should be included in the punch hole but in the case of a brick wall, the sill is part of the masonry and should not punch at all (but we need it to be part of the compo). An earlier version permitted that by not considering groups inside the compo for calculation.
The following is not right.

If you look at the rear of a normally cut-component that is what the hole-punch duplicates.
In the case of a sill with projecting 'horns' IF these are a z=0 in the component definition they will cut a hole ?
If you move the 'horns' ~1mm in front of the wall face line they won't cut and then they won't punch ?
See this...

WARNING!
Someone noticed that if you select punching components from the Outliner the matching reveals don't auto-select with them - unlike if you do the selection manually ! It seems the 'observer' for the selection is broken in the API [not specifically this tool!] when the Outliner is used this way. Therefore if you want to select the punched-components and their reveals don't use the Outliner!
-
I've had really weird results lately - but I know my openings are also weird. I could fix them though and was in too much in a hurry to report here but once I have the time, I will collect them to (hopefully) improve the plugin.
Great tool!

Ok, that should do just fine then. Thx.

Very helpful plugin. Thanks
