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

magazines · 27 Nov 2018, 21:36

Hi.
This is a fantastic plugin that has made models possible for me in sketchup that I thought would never work.
That said, I'm posting here because I am having trouble with the follow me pushpull part of this.

I have a project to extrude letters from a line form down to a near cubic form. 8" tall letter in edge form extruded by 10".
Linear letters work great! T, 4, N, etc all are fine. But curves, man, they're a problem.

Looking around I tried to find ways to complete this kind of extrusion, but everything seems to cause messed up internal geometry. And I tried the basic follow me, curviloft, extrude by rails, etc.
The best tool for the job seemed to be the follow me function of this tool. As I say, works great on linear geometry. But due to the non-radial curve of the letter forms O, G, Q, 6 - I'm just driving myself crazy here.

I'm absolutely not sure if there is a better way to do this, or if I am using FollowmePushPull Interactive properly here.
If anyone has any suggestions, or if I should post this elsewhere, please let me know.

Thanks for any help!

Seems you must have quadrangular hidden trimed geometry surface!

So take some cylinders and deform their Diameters after Joint PushPull as you want with Scale tool!

Hello!
I think I have tried what you are demonstrating. Here I pull up with normal JPP as your gif shows on the top face. I do see that a number of the faces are triangles and others are quads. Do you think this is the problem?
Here's another pic.
It looks to me that the issue is more about the extrusion causing intersecting planes.
When I did it before I used the followme JPP option pulling the flat face on the bottom, but it surely resulted in intersecting planes too.
I wonder what other approach I might take.
Thanks for taking a look!

Pilou,

You should move to the latest version of JPP, where the interactive selection process is more natural (and where bugs have been fixed too).

This one?

@Gilles : Oui mais maintenant il faut faire une "épaisseur générale" (pour je ne sais qu'elles raisons) avec le JPP !
Et c'est là que cela peut coincer suivant les natures des surfaces et leurs intersections!

pilou · 28 Nov 2018, 11:58

@Fredo Thx for the tip!

gilles · 28 Nov 2018, 15:04

Hum...

Je pense que le résultat recherché est plutôt ça.

pilou · 28 Nov 2018, 18:31

Personnellement j'avais compris que le JPP de manière générale avait des petits soucis avec les surfaces alambiquées pour en mettre une épaisseur!

Hello. Sorry, my last post didn't seem to accept the image.
Gilles, that is excellent! Yes, the thicker version is what I am trying to do. And I see there where you are making two follow me shapes intersect each other. I had hoped to extrude the thinner versions that I already had to the big fat ones rather than remake all of them from rails though. My problem seems to come more from a single one extrusion that intersects itself.

But Fredo, the newer version certainly makes a big improvement. I've attached a comparison on the "O" here. IT seems to work far better, leaving much fewer dense areas to fix. I will see how it works on the more complicated letters as I move forward. My only issue here is that I will need to fill in the edges where faces intersect other faces made by extruding the single letter form. Is there a way using the present form of the plugin to make planar intersections automatically produce edges?

Oh, and I think that you are right on, Piliou! I have a bit of wonky model making to fix!
Thanks!

Does the last version has "Vector" selected faces to a Plane ? (who is existing in the classical JPP)

Not sure I understand. JPP 4.4a is just a maintenance release. Functionality is the same.

pilou · 19 Dec 2018, 08:09

OK! So why this cool function (Vector to plane) is not more on the JPP 4 ?

fredo6 · 19 Dec 2018, 13:04

....what is Vector to Plane ?

pilou · 19 Dec 2018, 16:52

Ceci! Qui est bien pratique! Il semble qu'il ne soit plus dans la V 4!

It is still there. You may have to expand the button palette if it is in compressed mode

Damned! (the 3 little horizontal green arrows expand on the left!

Ok I have it but...

If it's works in 2015

It's buging in 2017! Drawing is good but at the end...so no drawing result!

Bizarre, vous avez dit bizarre ?

This bug is now fixed in v4.4b.
In your model, one of the faces is perpendicular to the direction of pushpull and thus would disappear. That's the issue.

Thanks for signaling.
