Project/Convert line in FS

papawo

can FS use project/convert line?

There isn't an operation or a sketch function in FS that does the same thing as the "project/convert" button.  If the thing projected is really a line, though, then you can evaluate its endpoints (e.g. with evEdgeTangentLines), use the worldToPlane function to convert their projections into the sketch coordinate system and use skLineSegment to construct the projected line.

Yes, you may see outdated errors in a Part Studio until you open that Part Studio again.  We're currently working on a way to make that more obvious when that happens.

The immediate problem I can see is that you're setting sketch1 to a 2d Vector (the output of worldToPlane) but sketch1 needs to be a sketch (obtained from newSketchOnPlane, which is commented out in your feature studio).  The 2d vectors need to be passed as the start and end of the line segment (which are currently hard coded to the example values, like vector(0,0) * inch.

im still getting error on start vector.
what is the error below means ?

papawo

I think i got it!

but still have this notice . what does it mean?

I think the error is for other code than what is in your screenshot (I would expect to see that if you typed "is vector" instead of "is Vector").

It would be easier for us to help with kind of thing if you saved a version of your public document when you see something like that and then posted a link to that version -- then we'd see the exact problematic state with the error.

The other thing I see in your screenshot piece is that vector(ptcoord, ptcoord) is very unlikely to be what you want (because ptcoord is itself a Vector), but I see that you fixed that in the public document.

ive change it to Vector but message still appear.
i reopen the doc again and the message is gone. 
thanks
