Can anybody help, I get this error with any object using round

This is in SketchUp 8 as your profile indicates you are using?

I can do this with a new document and a cube and I get this error or in an existing model.

Cheers,

I just found out about JPP Thickening. I use JPP for ages and never noticed it there and now it just solved an issue I had. Great! Just great!

Thanks!

JPP Thickening is just Joint Push Pull without a button palette. Which issue did it solve?

JQL

I was trying to offset all faces of a surface exactly 20cm and both the regular JPP and Normal JPP failed while thickening seemed to work.

Hello, I've been working with this plugin for a long time.
This question comes up in our German forum:
Almost all surfaces (objects) can be thickened.
Is it also possible to make an object thinner

without leaving the side edges and surfaces remaining? If it is possible, please write us how it works.
Many Thanks
Peter

Box

One of the setting with JPP is the second face, if you untick the that then moving inward will make things 'thinner' if that's what you mean.
If not, you need to show an example of what you mean.

Peter Czy

It's right, the objects get thinner when I push inward. However, edges and surfaces remain that have to be laboriously erased on a complicated object.
I mean those edges and lines marked with red arrows.

Many questions, many possibilities.
Can you not Scale the object or Move the face.
The problem with questions like this is there is no single answer, so much depends on the shape and what you want the result to be.
Attaching a model would help.

Peter Czy

Its only a simple testfileIt's just one question.
Use Joint Push Pull to thin an object without creating edges and faces.
If I just move the face, the thickness won't stay even. The same applies to scaling.

Box

Often the tool you think you need isn't, a simple offset and follow me is another way to do what you want, PP to correct the ends if necessary.
The main point being that there are many ways to do things and some times it pays to think simply.

Peter Czy

Ok, thanks for the other option to change a model. That was of course a very simple test model.
The time required for your option is similar to that of deleting these surfaces / edges according to JPP.
In principle, we don't have an exact answer as to why these edges and faces remain when the object is thinned.
I am sure that only the developer fredo6 can answer that.
I will post this result in our German forum.
Thanks again.
Peter

Box

The reason the edges and faces exist is the nature of the tool, it is pushing back following the face and therefore creating extra geometry.
This is not a bug of a fault in the software, it is doing what is expected.

Use the undo option and jpp less.

Dave R

Pay attention to what is actually happening when you use JPP. It's extruding in the direction of the normals of the faces as it is designed to do. As Box indicates, it's doing what it is supposed to do even though that's not what you want. If you must use JPP to add the thickness and you want a different thickness, the easy thing to do would be to copy the original surface and run JPP to extrude to the desired thickness.

Peter Czy

Hello Dave and Box,
Yes, I think the best option is to erase the face that has already been made too thick and recreate the reduced thickness.
Thank you!
Peter
