Polar stretch help

Recommended Posts

robwell

I have a dynamic block with many features and several visibility states. However, I am having one issue with Polar stretch.

 

I have a vertical pline with a short horizontal pline perpendicular at the bottom. I have the polar parameter and polar stretch attached to the lines to rotate around the upper end point. I want the short perp. pline to stay horizontal to the polar stretch point, but am having difficulty figuring that out.

 

I have tried a horiz. geometric constraint, but I need the line to stay a set length and it wants to shorten as I rotate it. I have tried a locked constraint, but I need the pline to scale when a lookup scale factor is selected and it won't scale.

 

Any help on this would be appreciated.

Can you post the .dwg?

Posting the block or a drawing is unnecessary.

 

All it is, is a vertical line with a short line horizontal off the bottom end of the line (could be joined or individual lines). Think of a section cut tail.

 

The pivot point should be the top end of the vertical line. The bottom end of the vertical line is the polar stretch point.

 

I would like the horizontal line to pivot (staying horizontal) at the polar stretch point, while moving with the polar stretch point (staying "connected" at the ends of each line).

I figured out my own dilemma. I needed to use the parameter set of 'Polar Stretch Pair' to keep the horizontal line horizontal while polar stretching the vertical line as it stretched in both x-y direction.
