cool, thanks for testing fellas

Hi all,

I try to use the plugin to create a skin within an angular 3D model.
It gives some trouble at a point where 6 edges intersect. The plugin creates a new point, after averaging all 6 normals to the faces, but keeps the edges together. I would like to see a result where new lines are created and previously horizontal or vertical edges stay hor/vert.

Is this plugin or another plugin/function in SketchUp able to do this in a single operation or do I have to adjust it all by hand?

I installed this tool months ago, but only just realized what it does. Another great plugin from Fredo6. Thank you.
I read through the suport literature and cannot repeat something I'm seeing there: According to the support document, if my neighboring face normals are less than the angle of influince from the target face normal, the they will influince the targets offset. Correct? I tried to re-create what was shown on page 13 & 14 of the document, but my model seems unaffected by angle of influince. Did this functionality go away in later versions, or am I mis-interpreting something?

Hi engineeric:
In your image, did that one face not extrude in a multiface selection and extrusion? Occasionally, this may happen, or it seems it has happened with me. Maybe the selection was made appropriately, but that face was spontaneously deselected?
In this simple example, you obviously could construct the missing portion by using JPP by normal or by vector, or even draw the completion with the pencil tool. In a more complex example, any of these corrections could get tedious.

I think OP is looking at how the angle at the sides of the extrusions are normal to the extruded face and not influenced by the angle of the adjacent face.

It has been a while since I did this similar operation (the faces on the left). As I recall (and I probably have that file) the edge faces did angle outward and not come out square. I can't repeat this now myself...so, good question.

engineeric

pbacot is correct. I've attached the relevant portion of Fredo6's support document to make the point clearer. In attempting to reproduce his example, I find that no matter what the angle of influence is, I only get the results of the Fredo's middle image. That is, extrusions next to deselected faces are normal. pbacot, you said this feature worked before. I wonder if your file was done with a previous version of JPP? I grant you the support doc is now 4 years old.

Hi there,

This script is very close to doing exactly what I need, and I'm hoping somebody might help me figure out how to take it the rest of the way... I'm trying to take roof systems that are drawn as single-faces, and then vector push them vertically into their proper thickness. JPP works fine for this, but it ends up with vertical hidden lines between the upper and lower face, which make it messy to turn the final roof into a solid, which is necessary for further editing. Outside of going through the complex roof form and deleting or filling-in every hidden edge, is there a way that vector push pull can just make a standard solid geometry?

Thanks!

Look through the tools options [and help docs].
You can set it to retain the original face, and also NOT to make 'internal partitions'...

Since JPP 2.0, the angle of influence is not used any longer (see release note).
I don't remember why I had to suppress this.
I'll try to have a look at the code to see if I can re-stablish it

incredible, thanks.

Hello,

I discovered and tried your tool with the last Catchup edition 15 to create the Hans Wegner chair.

Following this tutorial, I discovered that 2 of the 3 extrusion possibilities cause problems; the J and N where the result pulled face creates unclosed faces. The problem doesnt occur when we use the V tool.

The attachments illustrate the problem.

Regards,
Alain

@Alainbo

Tiny differences can cause issues with SketchUp/OpenGL that filter down through the API code.
Two points can end up appearing to the 'engine' as being coincident when they are not and thereby a face is missed off. In your case it looks like a creeping tolerance issue.

To avoid this if you scale up what you are working on [temporarily] by say x10 chances are that the extrusion vertices will all play nicely and no faces will get omitted. Scale back down afterwards and the issue won't reappear - it's the creation involving small dimensions/edges/facets etc that's the issue, but they can exist, just not be 'made' at those values.

AlainBo

Ok TIG, I'll try to work like that.
Thanks

Genius plugin
Thank you very much

I'm another mac user experiencing some issues with this incredible plugin, (but I'm banking on user error). I thought it might be due to running SU 7.1 on a G4 mac, but after reading the previous posts I'm not so sure. JPP works for me 1 out of 20 times. The other 19 I have to hard reboot the computer. What I've tried:

Verified the latest versions of plugins
Scaled the model up (twice)
Cut larger faces into much smaller segments, pulled one at a time
Tried while grouped/ungrouped
Removed all other plugins and reinstalled FredoLib and JPP only
Many times I let the computer sit untouched for hours, just to make sure I wasn't causing the freezes by interrupting a process

I've attached a model of a simple curtain I'm looking to thicken by 1/16" (either direction). The model is cut into segments, and all segments would be JPP'd (verb?) out to the same thickness.

If someone could point out the error of my ways, or take a crack at thickening it yourself, I would be indebted indeed.

Hi wtrouser,
I tried to thicken your model on SU 8 Pro M2 and the last plugin and I got the same result as you.
Even scaling it up by 10, all push-pull tools end in an infinite loop....

wtrouser

Alainbo... thanks, that actually makes me feel better. I tried x10 and x100, and I segmented the big face into something like 15 segments. Frozen pizza. Perhaps it's too complex of a face for the plugin?

AlainBo

Perhaps. It's a pity anyway. 'J' tool could be a very powerfull feature!!!

TIG

Worked fine for me.
Scaled it up x100 first.
1/16" >>> 6.25"
JPP keeping original faces and no partitions.
It became unresponsive about 13% in, BUT that doesn't mean it's bust !
After 3mins it completed OK.
Scale down 0.01 to return to ~6' high...the proof...
