sketch

After hand drafting for 20 or so years, I'm learning Onshape. This is my first CAD program. I've been putting in hours of study, listening to tutorials, following and making test sketches, with a fair bit of success. But as soon as I try to make my own sketches for my work (lighting design), I am quickly confounded by my…

So I thought I had overcome the learning curve but appears not: Basically i want to draw a line from point A to point B (seems simple but its part of a more complex program) using defined points from the user. annotation { "Name" : "Select Leading Edge", "Filter" : EntityType.VERTEX && SketchObject.YES, "MaxNumberOfPicks"…

I created 2 semi circles on two parallel planes that are offset from eachother. I then created another plane across the flat sides of the Semi circles and im trying to sketch 2 lines from the outer points of the semi circles down that perpendicular plane. but the tool wont snap to the outer points, it will only snap to the…

Hi all, In my great noobism, I'm looking for a "rack and pinion constraint" or something of the effect, like having an equal length constraint between an arc and a straight line in sketch. Does anyone knows how to do that? that would be a powerful enabler for cycloids, trochoid, and all things in "oid" you wouldn't want on…

I'm trying to put a rounded corner on a rectangular extrude using the Sketch fillet operation in sketch. Contrary to what the pop-up help message says, the sketch fillet operation does not recognize or select the corner of my sketch. Is there some trick to getting the function to select within sketch?

Hello! Quickly, I created a "main sketch" and extruded a couple of solids from that. Then I went back to the main sketch to add some other entities and the first solids now have voids! OK... modify the solid and add the "new" sketch regions. But when doing a Use and Trim something I am not use to is happening. I quit…

Hi all, I would like to share some tips which could minimize the additional task of projecting the part edges wherever possible. According to my CAD experience I generally avoid projecting the part edges since for some reason projected sketches may fail in later stage due to changes in other geometries. In other CAD tools…

I've stumbled across that an Ellipse can not be selected to Extend in a sketch? Although I did figure out a way to do this! I drew a line from the center of the ellipse out past the ellipse for convenience. Then I picked the end point of the line, then the ellipse curve and made those Coincident. After that I picked the…

Great update! First I tired "Fix" all entities in existing sketch... pasted sketch has all entities "Fix"ed. Eliminating need to redimension new sketch.

If you take a look at the attached image, the top gray line is a sketch (s1). The bottom blue is the face of a part (p1). p1 is an extrusion of s1, but you can see that when zooming in, they don't line up visually. This causes a few different artifacts in my drawings, including floating lines on the faces of parts, etc.…
