Quadrants with rotated ucs

ttorres74VVR — Fri, 29 Jan 2016 15:21:29 GMT

I have a closed polyline profile which has fillets in the corners. If I rotate the ucs AutoCAD does not locate the quadrants at the rotated ucs. It only finds the original quadrants before rotation. I need this for dimensioning at different angles. I realize I can explode or draw a temporary circle, then AutoCAD finds the new quadrants, however I'm hoping there is a setting in AutoCAD for this problem. Thanks to anyone that can help.

Welcome to these Forums!

I find the same, though interestingly it does Osnap to quadrant points of Circles from the current UCS's perspective [and presumably Arcs -- I didn't try them, but it must if your Exploding approach works].

A workaround that doesn't involve either Exploding the Polyline or drawing any temporary objects is this:

Have CENter and INTersection among your running Object Snap modes, and either Ortho [F8] or Polar [F10] tracking on, and Object Tracking [F11] on.

Then you can, for instance, in a rotated UCS, start a DIMLINEAR command, and for each definition point, hover over the filleted corner arc segment so that its CENter mark appears, then hover over that center mark so that it "lights up," and head toward the quadrant you want with Ortho or Polar limiting the direction indicator, and you can snap onto the INTersection of that directional indicator and the arc segment.

Correction: I discovered, in a trial for suggesting the same approach on another thread, that this does not work in Ortho, but only in Polar mode.

This works great using (F11) by itself. (F10) ortho does not work as mentioned in the second post. Thank you much.
