Thank You TIG,

it works fine, but needs a lot of time for my geometries.

Is it possible to speed it up or if not, to implement a progressbar?

It still runs 30mins for 200.000 edges, no end in sight. I will abort now.

I will try with 15.000 edges and post the needed time when its done.

I tried the recurve.rb plugin, without sucess.
It does not work with nested objects. Any other suggestion? Is anyone able to edit the weld.rb to run for nested closed lines as well?

Thanks mitcorb,

you are right: I need "En Masse weld".

I already tried the plugins you proposed, without success.

Could anyone help please, its quite urgent.

@ forum moderator: could you please move the thread to the right forum section, thanks.

Hey SU community,

I have the following problem using the weld.rb plugin:

I have to convert all edges of my model to closed polylines in a single step (the model is very complex) prior the dxf export for autocad.

Because I have nested geometries, the plugin does not work in the right way, I have added a simple test file. The plugin only works if I select the box and the text sequentially.

Is there a way to add some code to the weld.rb plugin to get it working with my geometry? My modell has ~4 million edges that have to get converted to closed curves (autocad polylines) with a single selection step.

Thanks in advance,

Marcel

I think I found a way to do it =).

I just project the geometry onto a curved surface. Than I export the view as 2D dxf.
So,the imported dxf contains the distorted geometry. The distortion value can be controlled by the fov of the camera.

Hey SU Community,

is there a way to distort 2D geometry with a clever Sketchup Plugin like that?:

Distortion (optics) - Wikipedia

I want to pre-distort geometry for an optical application.

FredoScale is not able to do that.

many Thanks.
