Re: Custom Feature: Gridfinity Bin & Base Generators
This is a great piece of work which has saved me hours in creating my own designs!
I wanted to bring to your attention some observations when I checked out the unofficial "specification" at the link: Gridfinity | The modular, open-source grid storage system for your workshop. I don't know if I am missing something but it looks like your bin base and stacking lip are ever so slightly different from that document. I've highlighted the dimensions which look out to me in the sketch below, which shows a cross section of a base below a bin with stacking lip below another bin. Specifically:
a) dimension of the 2.4mm wide face of the bin bottom vs 2.1mm in the "spec"
b) clearance between bin bottom and base is a little larger than the "spec", 0.427mm vs 0.25 (technically I don't think the 0.25 of the "spec" is geometrically possible anyway)
c) the slope of the stacking lip isn't 45 degrees.
I reckon these differences are well inside the printing error of most 3d printers anyway, but I thought it would be useful to run this past you in case there is an issue here. As an engineering document, we might as well be accurate, in case it finds application in more precise manufacturing processes.
Re: Product Catalog (New Custom Feature!) 🆕
Yes, although it would be even cooler if Onshape did it automatically when it recognizes the same geometry and properties. It would be nice to override it if the properties are different but the geometry is the same.
Re: Product Catalog (New Custom Feature!) 🆕
Agreed. Would be great if we could tag parts with a special attribute that would let the assemblies know to that these two parts are supposed to be counted the same in the bom.
Re: ¿how to make a rectangular spiral?
Already two great solutions above. But, if you wanted even another way, a quick FS will do it.
Re: ¿how to make a rectangular spiral?
Kevin's will be the most straight forward way.
Here are a few more steps you could take to make the loop count dynamic with a feature pattern:

Re: ¿how to make a rectangular spiral?
You could certainly do it with a Custom Feature, but creating a seed sketch and repeatedly offsetting it will also work (bit more manual). Particuarly if you drive everything off of one variable, you can edit that number and scale the whole spiral. Made a quick example, pretty fun!
Re: Exclude Parts from Drwaing(s)?
Ah! Thanks a lot. I completely forgot about diplay states being available in drawings and search in the help/learning section didn't reveal it either. Both these methods work on a per view basis, with display states, it being a kind of preset, appearing a bit more manageable, while sow/hide parts is quicker on an individual view. In my current case I now made a with / without assembly fixture drawing state and that pretty much does it, even if I have to activate it for every view. I just made a second sheet with the other state and hope this way it'll only need to be set one time and can be controlled from the assy when modifications need to be made.
