Re: Difficulties using guides with the loft
Looks doable. Please make the document public so others can make a copy.
Re: Struggling to turn a curvy 3D-scan mesh into a worthy surface
Good morning MDesign. I played with the profile splines but not the guides. Hopefully would have found and improved those as well but needed some sleep. The distortions on an old cowl are not a surprise, From the time frame these Citabria Cowls were made the original plug was probably hand shaped with the inaccuracies that involves. Over time they will also distort some due the wear and tare and stressing as well as patches under the paint. The idea is to get your development faired as best you can. Some hand blended fillers around the edges and across surfaces during install.
For a few years I did this kind of work as a side line. One customer had molds that had been stored so badly that I couldn't work with them and had to rebuild or simply build new. I was surprised at how much distortion could creep into fiber glass parts and molds over time. Had some time this morning. Replaced guide curves after editing profile curves and opened up tolerances. Doesn't look too bad. Only 1 or 2 spots I'd like to smooth a little more but need to get on with other stuff.

Re: Partial circle centreline
If you modeled your part with a hole feature and circular patterned that - we do provide circular centermark patterns as a part of view creation. You can edit the automatic circular centermark patterns and unselect the same elements as I did in the manual tool, and then adjust the arc centermark extension in the same way as above.
Re: Improvements to Onshape - January 31st, 2025
Hey I just got a new project and I could really use the sheet metal loft feature 😅
Please hurry, I don't want to use traditional CAD 😑

Re: CAM Studio - open pockets on edge of workpiece
CAM Studio doesn't accept sketches it appears. As a pretty messy workaround you can create a new part though that extends the slot out to make the cut appear to the toolpath generator as a full pocket. See V15 for an example.

For a single slot this isn't too bad but for a complex part I can see this workflow being pretty tedious.
Re: Why do my sketch lines disappear when I draw them
Probably a browser glitch… Try refreshing (ideally a "hard" refresh, SHIFT+F5 on Windows…)
Re: Cutting Bricks
Draw your desired path. Then do an offset the width of a brick. Then draw your bricks. The longest side of each brick should be equal to the length of your brick and the shortest edge should be normal (shift+k) to your path.
Re: CAM Studio - open pockets on edge of workpiece
Can CAM Studio take a sketch as input? If so, you could create a sketch that duplicates the slot dimensions, plus enough extra at either end to let the cutter clear the stock or ends of the slot.
