Need help creating steps on a Nose Cone
Hi, I'm working on a school project where I need to model a bunch of tiny steps onto a nose cone. The finished product will basically be a nose cone with a bunch of concentric ridges (1000+). I have the nose cone modeled, but I'm having trouble creating the little ridges. I've tried using feature pattern, but it doesn't seem to work. Can I have some help?

The example above was for even vertical steps, if you want even radial steps you can start from teh top like this:

Hmmm ... not sure what purpose these ridges serve and what rules they are to follow. Constant ridge angle? Constant slope width?
A crude approach could be like:
If we knew what rules apply, there could be a more parametric approach.

This would be a pretty simple Custom feature to write. Like a basic slicer - I think a few people have done so in the pas (and I know this guy "Claude"….)

Yes, probably a Feature Script. I think it would need to be a bit more elaborate than a basic slicer, because delta Z would possibly have to be modified for each slice.

maybe I could help if you actually let me copy your document.

I was going to suggest using the Topographinator FS but it's kind of the "reverse" of that…
It could be a good starting point to create an FS for that.I think this could also be done with a pattern and variables though, as shown here:

Yes, that's also nice, with the corner of the copied rectangle always being trapped on the curve.

Hi, thanks everyone for the replies. Apologies for the specifics, I'm relatively new to this. Since someone was asking, I'm actually modelling 3d printed nosecones for fluid analysis!
