Thank you very much.
Used to feel very good.
Sorry.

Is it JPP polygon-limited ?
I have a curved face and I wanted to add thickness to it. Unfortunately, JPP only affected a part of entire mesh.
See below.

Could it be that the faces were pulled internally because of the direction of your pull and the inference engine trying to snap to a vertex? I don't know, just asking.

I'm not sure what you are asking...but if is what I think it is, it should be valid only for small distances and only for mouse movement. Or, I moved the mouse to avoid snapping and I input a value in VCB.

JPP has a limit for displaying the feedback wireframe (5000 faces) but I don'th think I put one for the processing.
I'll check that and come back.

Hi Fredo,

I've Joint PushPull assigned to 'J' shortcut. When I select all geometry and press 'G' to 'Make Component' then 'Set component axis' if I press 'J' during the placing of the axis SU will Bugsplat.

It doesn't do this for any other keyboard assigned plugin.
It doesn't do it if nothing is assigned to 'J'.
It doesn't do it if a native tool is assigned to 'J'.
It doesn't do it if another plugin is assigned to 'J'.

There are no messages in the Ruby Console. I'm using all the latest version of your plugins.

I know that not pressing 'J' solves it

After a few days, I'm still struggling to give one of my hollow models some thickness.

I created a model that looks sort of like this (i.e. a curve spun around the Z axis):

I then select everything, click Joint Push/Pull, and enter a distance that is my desired thickness (e.g. 10mm). Some sort of calculation happens, but when I check on the model's thickness, it appears unchanged:

What am I doing wrong? How can I get the walls to be thicker?

Here's the model in question itself (attached).

It worked for me although I probably added the thickness in the wrong direction.

After you select the JPP tool, hit TAB and make sure you've selected "Thickening". If you have "Erase Original Faces" selected, the original faces will get erased and you won't get the thickness. Another thing I did was split the operation into several smaller ones by selecting sections of the shape. I started at the bottom and selected just the surface below the belt and ran JPP on it. Then I worked my way up from there.

I would have guessed that faces need reversing, and overall size of the object would need scaling to produce the effect, but this may not apply here.

Dave R

You're right. the faces were all reversed but that and the size of the thing didn't affect the operation in this case.

Helios, I did forget to mention the face orientation thing and that you ought not to work so far from the origin.

I updated the file to put the thickening on the inside so the little detail at the top shows correctly. The model could stand a bunch of cleanup but I'll leave that to you.

Wow, you guys are awesome. Thank you so much -- this is way beyond what I expected for help!

hi This is great script and use it often in creating stuff for my Hammer editor(source), the only thing it takes a while cause i have to do each face separately, is there or is it posible for this script to allow me to select more than one face and then group each face separately and still get the same results, (not sure if this would cause overlaping solids)

JPP precisely works on group of faces (just select them and activate the script).
Unless I miss something....

thank you very much!

Thank you so much Fredo!

im trying to push down a curved surface but can't get the desired effect , my shape get slivered on the edges. and i have to delete lots of curved faces one by one. how should i decrease the thickness of solid the way a normal flat solid would work?

pushpull sample.skp

Dave R

Joint Push/Pull is working normally. It just pushes all the faces in the direction of their normals which will leave those faces.

For something like your example I would either draw a curved face where you want the new surface to be, intersect it with the existing geometry and then erase what I don't want or I would draw a 3D shape and use the Solid tools to subtract the stuff I don't want.

solid tools and booltools often don't work since we have little hole in our geometry. so they don't get qualified as a solid. Intersecting faces is an untidy and a bit long way.

Dave R

Sloppy work results in harder work. Don't work harder than you need to.
