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

[slb_jwm]

Joint push pull Joint and Thickener both fail with errors when I try to make this skin (part of a geodesic dome of frequency 3) thicker (by 3/4"). But they only do it when the component is part of a larger model.

In a separate model, both those forms work, but only extrude normal to the faces (as designed).

Extrude works, but takes only an average direction, presumably along the radius to the centre of the hexagon.

Feature request: could there be an option in the existing plugin to enlarge radially from a given centre? Either the origin of a component opened for editing, or perhaps picked by the user?
Trying to thicken this radially from its origin.

I've managed to do it approximately with the Scale tool, but can't get it to scale to an exact thickness of 3/4"

Is this what you're trying to do?

[fredo6]

JPP Thickening is done along the normal of faces. If it happens that all faces are perpendicular to the the radial dierction, then it is OK.

Installed libfredo6 11.4f -> JointPushPull is not awailable and cannot be installed anymore.

Where are you looking for it?

If you have successfully downloaded Fredo's extension as an RBZ file, then you still need to 'Install' it... using the appropriate button on SketchUp's 'Extension Manager' dialog...
But note that, as explained in the extension's notes, it also requires you to download and install a suitable version of the Libfredo... RBZ... [>=8.7]
After that you will need to restart SketchUp to 'sync' the loading files...

Fredo6 Libfredo6 is installed (Version11.4f) is installed
Still cannot install JointPushPull - a Sketchup 2021 problem?

I could use JountPushPull in Sketchup 2020.

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]

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.

[Dave R]

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

[iggi]

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

Regards,

[fredo6]

@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.

[rv1974]

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?

[rv1974]

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.
