Re: Progressively smaller feature patterning
you could try the increment variable FS put that in your linear pattern (feature pattern) and indeed make sure 'reapply features' is on.
Re: How can you wrap/ project a pattern onto an irregular lofted surface? Is it possible?
The Attractor Pattern did exactly what I needed. Thank you!!
Re: Issues with loft function
It's a little hard to tell all we need to know from the view-only link (can you make it so we can copy?)
But there are a few obvious things starting with the profiles:
- the curvature is extreme, in fact goes more or less to infinity, at the trailing edge. This won't go well in your loft…
- looking at the leading edge, the curvature is also suspect, but the diagnostic combs can't capture the full extent since they are being scaled by that trailing edge….
- You have a single spline for the full profile. It is much better to have 2 splines, one for top surface, one for lower surface of the blade. This is especially true if you are using a zero thickness (sharp) trailing edge (and the reason for your bad curvature at the TE currently)
- the spline has a very large number of points. It would be better to do some smoothing and reapproximation. What was the data source you sampled these points from?
I think with cleaner profiles the loft would be much more successful, so I suggest looking at that first. The path with 50 sections will be the next thing once the profiles are addressed…
For clean aero profiles there is a custom feature I helped develop last year. Give it a try, there are some links on the description page to provide more background. While there are many (about 95) different profiles included, I don't believe NACA8710 is one of them currently. You might want to contact Holbrook Aerospace if that one is vital.
Re: purpose of setting the origin or chosing a new defined mate in a context design?
What I meant was that the new part's coordinate system would match (better than follow) the mate connector.
This helpful if you need to create an in-context part that is not "aligned" with the assembly x,y,z axes.
If you create the mate connector in the assembly and use for the in-context part, then you can create a mate connector at the origin of the part and mate that to the assembly in-context mate connector.
Then your part will follow that assembly mate connector. Note that context don't update automatically, you have to intentionally "update context" if you move the mate connector in the your assembly for the part geometry to update.
Re: Introduction to Onshape Simulation - lesson
Simulation is available for Educator accounts, not Student accounts. In order for students to be able to perform simulations, they need to be added to an Educator's Classroom.
Re: 3D Texture
1) The end caps are simple 2D patterns. The grill is a simple fill pattern (https://cad.onshape.com/documents/57361ad4e4b00e5012c3857c/v/eb8bfe2edd984a315033e6e2/e/14aa44d127806651b248b9c6)
2) This is doable - it's pretty manual unless you want to write a custom feature to automate this.
3) The end caps and grill can be made with the 'lighten' feature. The facetization can be created manually, or automated with a custom feature. (https://cad.onshape.com/documents/573f7d70e4b0fddafb52148c/v/a8a36f6d743269e1b6886711/e/2dc22a6a95896a5243812d07)
4) The ornate grill is a simple pattern. The end caps are not something that a b-rep modeller can easily handle. This type of geometry is not something that you will want to do in Onshape (or any other modeller - eg SolidWorks)
Another custom feature that may help is the surface pattern feature.

Re: Optics: Custom Feature
Absolutely brilliant, and perfect timing. I was trying to make a light to illuminate my cockpit from a single source, and this gave me a great lens to try as a first step:
Re: Golden angle pattern (Sunflower)
@Ste_Wilson How do I share?
I suppose you all could just do the same with your version of Grok 3. (I have SuperGrok)
Prompts:
************************
I need you to read and understand the following program called FeatureScript 1188 do the following: Remove anything that is not related to the Fibonacci pattern. I only want to make a Sunflower pattern. Make the program lean, as there might be some sloppiness. Fix any other errors you see.
************************
I need to have the ability to set an inside diameter and an outside diameter as the limits of the sunflower pattern. Then I need to be able to set the count of how many of those patterns fall within those inside and outside limits. So can you add those features in?
***********************
Also, this program is for generating a sunflower pattern so can you take out any reference to "speakers" and just use an appropriate name?
***********************
I got the following error "Nonconforming feature function 'SunflowerPattern': precondition analysis failed" "23:14 Speaker Pattern" can you fix it?
***********************
Those are the prompts I used to get the final clean code. Start with @EvanReese Speaker Pattern doc, use his code but add in the prompts I listed above. See what you get.
