Hallo together,

I want to make the attached part parametric. Can I have some hints.

Having very little experience with parametric parts, Rudl, I thought I'd try this one to see whether I can handle it. Experiencing considerable difficulty, but I am making progress. Perhaps I'll have more info for you in a few days.

Thank you for helping.

Gently asked, Henry, did you come a little bit deeper in the parametric.

Still having problems, Rudl, but I think I'm making progress.

Progress report...

Attached screenshot shows the part. The rear face is vertically grooved, too, but not the side faces. All of the indicated dimensions are controlled by Constraints; changing any of them in the Calculator Palette makes the part update automatically. Number of grooves is not editable; changing that requires changing the drawing.

EDIT: I changed the drawing (and saved under a new name!) to increase the number of vertical grooves. Dimensions are still fully editable.

Excellent, could you give further details.
Or can you upload the TC-file.

Thank you

"Parametric Fluted Column.tcw" is the part itself. "Parametric Part Dims.tcw" shows how the dimensions of the part are represented in the Calculator Palette of "Parametric Fluted Column.tcw."

Don't hesitate to post questions.

Fantasic use case and interesting solution.  However I'm a little confused because after looking at this a little more in depth I don't see where or how I make it a true parametric part as we intend for this functionality to work.  Essentially there are 2 methods the automated on as demonstrated by this little movie:

http://downloads.imsidesign.com/TC16/PPMautomatedmethod.wmv

And the scripting method for creating Parametric Parts and some examples in the PPM topics section of the forum.
This reminds me of the picket fence PPM.

Let me get some internal PPM experts to see this and give some feedback.
If nothing else this will help us identify where we need to go with this functionality.

By the way there is a scripting method for creating Parametric Parts...

Yeah, Dave, I'm aware of that, but a quick look at the documentation left me feeling dazed ;-)

It's also my understanding that this drawing could be massaged further so that the parameters would be accessible via Selection Info palette (I think), which would be a lot more friendly than editing values in the Calculator palette. I'll probably explore this in the near future.

Thank you very much, Henry, for this brilliant example of working with constraints.

Did you try the other way with the Pp´s.

I like your work, and I hope that you can find a way to make this in Pp.

Once again, totally impressed.

I have never tried constraints, and I can't spell para-whatever.

Perhaps I follow the KISS rule a bit too closely.
