Re: Optimization for 3D-Printing - Split up part for glueing
Oh man I enjoy this topic!
imo removing the supports from this part would be less time and effort than connecting 3 separate parts. It's also not a stretch to make this part print as one piece without supports. Here's an example:
https://cad.onshape.com/documents/6d7e50b58ed12052b0d5688f/w/b2ba3a237a24b424e83cc81e/e/46c8d3f93123a787c4b67349
If you're trying to design for a maximum overhang angle (45° is a good default), you can use the built in draft analysis tool to check on your design like this. Dark blue areas have a greater than 45° overhang, so just make sure they are intentional.
You can also use the section view tool to scrub through the part and imagine it printing layer by layer to make sure you're not asking it to do anything dumb, like print something in mid-air.
There are a number of 3D printing DFM related custom features available.
Ones I've written
- Bridge Layer - Helpful when designing for unsupported holes aligned with the print Z axis without supports
- 3D Printed Hole - Converts round holes to a teardrop shape so they can print well without supports while staying as close to a circle as possible
- Captive Nut - Used to design pockets meant to receive nuts. A great way to add strong metal threads to 3D prints
- Grid Extrude - Automatically make grid patterns, like hexagons and so forth. Not strictly a 3D printing feature, but useful for it.
Ones from other people
- Bridge Counterbore - Automated a very clever workflow for printing unsupported z-axis holes that requires no post-processing.
- Tapless 3D printed Thread - For creating holes to screw thread into directly
- 3D Printed - let's you estimate the weight of parts based on materials and infill settings
Re: New Custom Feature: Publish Geometry
@GregBrown 's Publish version in his YouTube allows selecting sketches directly - and they persist as sketches in the derived feature. Anyone know how that can be enabled?
Re: New Feature: Attractor Pattern
Thats a super cool use of the shrink wrap feature!
Re: New Feature: Attractor Pattern
Nice tip! Good looking results too. I didn't know about Caden's feature. My Pull Surface to Part feature was made for this purpose too, but it's enough of a hack, that I'm inclined to re-write it from scratch sometime.
Re: Set Color and Material - New FeatureScript
@NeilCooke are there any plans to integrate something like a material/property-based automatic part coloring, that can be toggled? We like the automatic part coloring for designing multiple parts within one PS but it would be really helpful to switch to a view where all parts get a specific color based on the material and maybe a property (that describes the Surface finish).
Re: Drawing circle from midpoint cause "Sketch could not be solved."
for simple designs it doesn’t make much difference other than the reason you mentioned. But when designs get complex it’s my understanding it can be preferred to do repetitive stuff outside the sketch when possible for performance reasons. I just try to make it a habit.
Learning about tools through experience doesn’t make you a Neanderthal … it makes you normal. Ha.

Re: Drawing circle from midpoint cause "Sketch could not be solved."
seems a constraint is conflicting. if you share doc as Neil suggested someone can help narrow down what the conflict is. putting a circle on a midpoint works for me.

Re: Drawing circle from midpoint cause "Sketch could not be solved."
Looks like your design is a great candidate for one fourth of the work you've done. maybe 1/8 with the use of mirrors and a circular pattern. A couple suggestions. use equals contraint rather than inputing variable reference for every dimension. When there's opportunity to use mirror and symmetry and patterns its highly desirable to do so.It will help avoid over constraining and narrow focus to minimum number of entities to make it easier to troubleshoot

Re: Drawing circle from midpoint cause "Sketch could not be solved."
Your sketch could be as simple as this image or even simpler if you want to do the fillets on the solid model instead of in the sketch. the hole tool can be used to create a counter bore through both parts using the points as shown in this sketch. and the feature tree might look like the 2nd pic.

Re: How do I get the extrude remove to intersect with the surface?
Make your solid extrude part first, then Boolean subtract it from the surface part.
