Re: Vehicle coordinate system
It is definitely an interesting one, and I've been dealing with it in one form or another, in multiple different CAD and CAE pacakges for the best part of 30 years. The thing is, the are multiple conventions and at least a couple of Standards depending on what part if the design you are talking about. e.g. ISO 4130 (which aligns X+ axis along the car toward the back and Z+ is upwards, though ISO8855 (used for vehicle dynamics) which has X+ along car but toward front, and Z+ upwards)…
I recall at least one (most?) of the US big 3 using this ISO4130, but the next question is the car origin. Some set X=0 at the front of the car, or even in front of the car so all values are +ve, some set it in line with the front axle (common in trucks, especially useful when doing weights and measures calcs), others have some reference origin at some point on the engine, or on the firewall. Z=0 can be at ground level, or not. It depends.
Some conventions flip Z so Z+ faces down. It depends.
But I totally agree there could be a lot more flexibility in choice the names that appear on the viewcube so on…. I'll keep an eye on that improvement request.
Re: How do I create a quarter-round edge cutout (cove), rather than a quarter-round edge (fillet)?

Re: Importing SVG files
This is NOT actually a solution. All comers… please disregard this useless link to a thread from 2017. I mention the date because it punctuates how neglectful OnShape has been towards this more than 20 year old, globally and nearly universally supported standard file format. OnShape has no native support for .svg files, which is embarrassing. The insert image tool mistakenly treats .svg files like raster files. Hello OnShape! Are you there? Did you know that .svg files are VECTOR?! As .svg files are VECTOR, comprised of MATHEMATICAL POINTS, there is no reason for OnShape to lack native and very reliable importing support.
Please, OnShape, give .svg file importing the attention it deserves. Treat .svg files as mathematical artwork, because that's what they actually are, and translate them correctly as countless web-browsers and illustration applications do so their artwork can be employed in sketches and CAD modeling.
Re: Sketch from Flat pattern
Sketch from Flat pattern
Either using the "project" tool or a one click convert would be nice and useful.
Otherwise it's not apparently possible without putting the pattern into an assembly and then generating a sketch from that. Which works but kinda clunky.

Re: How do I constrain all sides. When I try I get "Sketch could not be solved"
The length dimension (37) is already implied by the other dimensions (145-5-10-10-83 = 37) so you cannot add a driving dimension without overconstraining it all and making it go red. What you do need is some sort of dimension for the vertical spacing of those 2 blue entities. Or otherwise add a constraint to make them align vertically with the 83mm long line segment. Add one such thing and the whole sketch will be fully defined,
Re: How do I constrain all sides. When I try I get "Sketch could not be solved"
That 37 is unnecessary because the whole thing is 145 and you've got other horizontal dimensions (5, 83, 10, 10). What's missing is the height of that right rectangle.
Re: Vehicle coordinate system
at Honda we didn't use left and right, we use DR (driver side) and AS (assistant side, for the passenger side of the car, which can reverse depending on country). However almost all of our work was driver side only, except for a few things on the interior, such as the instrument panel (dash).
Re: Vehicle coordinate system
No doubt there are hundreds of users (most of them on Education plans) using Onshape to design competition robots: FRC, FTC, Vex and others. Teaching these CAD novices that the orientation of a new robot model should be chosen carefully doesn't carry much weight when "Left" doesn't really mean "Left" . Let's round up some votes.
