[Plugin][$] JointPushPull Interactive - v4.9a - 02 Apr 25

Hello,
I got an error with joint push pull extrusion in SketchUp 2020.

Date: 10-Jan-21 15:59:27
An error occurred in Joint Push Pull
Error in generation of the geometry

I guess you wish to push-pull all faces.

Then, you have a number of them which are ill-formed and there is nothing JPP can do about it. For instance, these group of buildings:

Einstein - JPP - faces 1.png

Einstein - JPP - faces 2.png

Einstein - JPP - faces 3.png

Einstein

Then would it be possible for the plugin to skip the ill-formed faces, leave them unextruded and proceed?
Ok, some of the faces are broken but most of them are OK. Why break entire operation due to a few wicked faces?

Dave R

Why not clean up the model before you add more geometry and potentially make more problems for yourself?

I concur with Dave. Better clean up the model if you wish to do something with it.

Detecting and cleaning the problem is a whole big task in itself. It could deserve a plugin. This is not like Sketchup tells you the face is ill-formed or not. Actually, these faces are toplogically valid for Sketchup but they won't work with many transformations and operations.

So, using a detection and fixing before operating JPP would be counterproductive and a big hit to performance in 99.9% of cases where the geometry is OK.

Thom Thom's CleanUp3 could remove coplanar edges to merge faces although it may not remove the correct edges. In this particular model it would be difficult for an extension to identify which edges should be removed.

Einstein

That's weird. I actually did a cleanup using ThomThom's plugin and JPP first threw an error. Then did a cleanup again and JPP worked fine.
I don't know why it happened but sorry for bothering you.

Hi everyone,

Is project shape on a plane possible on a Mac? I can't seem to find this option.

Thanks

Hi,
how do you report a bug?
(well, I believe that what I see is a bug, not a feature

version 4.4e, Sk Pro

@iggi,

Can you send me the model.

I think it has to do with the original circular profile sections, which are not generated parallel to the axes.

Fredo wouldn't it be fantastic to add context-free JPP mode for edges? It would demand some smart path selection tool similar to the one in profile builder.

fredo6

That's a different plugin, because the extrusion is based on contour lines, not faces.

Interesting anyway.

Which software is it?

some script for Max. If you could develop it for SU.. it'd have a huge advantage because
SU allows to 'hack' the context hierarchy.

Which script is that? Is free?
In Max I'm able to do 99% of that stuff without any script at all just using regular editpoly edge mode (just select the loop, set "normal" constraint, extrude/scale and then pull up and down without constraints).
But that corner options look intriguing btw..

I did a similar request to Thomas, because I feel that normal constraint is one of the few mayor tool still missing in the QFT/VT/SubD workflow.
Not sure this edge job is suitable for JPP itself which is more of a shell/push/face extrude tool.
But never put limits to the Fredo power.. Maybe some normal face extrude logic is reusable on edges?

Yes it'd be natural to expect tool like this from Fredo or TT. I also saw Whaat is working on all-quad Artisan 2.

Thank you. Too bad the download link doesn't work anymore.
