turn a copy-geometry sketch into extrude/revolve

turn a copy-geometry sketch into extrude/revolve

Hi, im working on a university project and new to the whole top-down design game.

I have already created a sketch and some datum planes in my skeleton model. (I have many variables, so there is a lot of references).

Next, I have published some of the sketches as a publish-geometry, so i can use it as a sketch for my parts which will be part of my assembly.

 

Now Ive got the problem that i just cant get the copied sketch to work like a normal sketch for revolving or extruding parts.

 

have already tried moving the copy-geometry around inside of my model tree (main assemby, subassembly, part), but the only way I could imagine using the copied sketch as a revolve/extrude sketch is by referencing every single line inside of my copied sketch and using it to make a new sketch, which just does not seem rigth.

 

Sadly, I also cant find any tutorials on this specific problem, because everyone uses the copy-geometry feature for already existig parts and not sketches.

Bonus question: should the publish/copy-geometries always end up inside the footers?

Yours very frustrated student,
Filip

This observation and statement are accurate. Your copy geometry from the skeleton (source) to the target part(s) does not bring a sketch but curves from the sketch to the target part. You must reference these curves to create a new sketch for features in the source model but there are tools to make it easy such as project->loop. There is one way I can think of to replicate the sketch in both models and drive it from a single parent object. To do this you would use a notebook (*.lay) file to define global parameters (dimensions driving the sketch) you would then declare this notebook to all models needing the parameters to replicate a sketch to be controlled by the notebook. I am not suggesting that you necessarily do this, I would need to better understand your design intent. If you can explain the logic and desired behavior of the sketch in the skeleton to be used in a dependent model, then you will likely get some advice on methods to capture the design intent.

 

I would expect when you provide details on your design intent there will be a better method to manage it than what I proposed above.

Thank you very much!

It was right to use the project tool inside of the revolve sketch and choose the loop option 🙂
