Generate Centerlines

sdmitch

Is there a plugin out there that will generate centerlines of components? I'd like to window a bunch of components and have it generate centerlines in order to speed up sending files to an engineer for analysis....

A rather interesting problem. Could you possible post a "typical" model version<=2014?

Here's a V8 attached.

I'd be happy to do this in '2d' in pieces, so I could generate centerlines for a typical bent:

you could add the centrelines in the components at first, so you
wouldn't have to add them

which would render them non solid, so useless for using any of the solids tools.

unless you put the centerline on a different layer you could easily remove
just an idea...

yes, just an idea, but my flow is to build the model and take it to a certain point before handing off to an engineer for review (often getting close with my own calculations, as well as having input from the architect / client / etc.

putting the lines on a separate layer wouldn't really help me out, as the lines still break solid, wether the layer is on or off, and i typically use the solid tools quite a bit before I get to the point of needed to generating the centerlines.

Make them construction lines that can be converted to "line"
There are 2 or 3 plugins that do this now.

Can we have a very simple image(s) of what do you want exactly as center lines? Short.. long ....
(on the 2D or 3D images above)

good idea

i tried: it works

Even with a construction line inside the component, operations are possible on volumes with sketchup pro

the modified component becomes a group, but if the goal is to get the centerlines only, just delete the surfaces and convert the construction lines into lines

just one idea plus just one idea...
