NightMist Posted January 27, 2013 Share Posted January 27, 2013 Hello, Suppose I have a rectangle 10 x 8 and then I join the middle points of the widths with a line ... so I will end up with 2 boxes of 5 x 8. Now what I need to do is to stretch the side by 2 units to become 12 by 8 but I want the middle line to move automatically during the stretching process so I end up with two boxes of 6 x 8. is it possible?

Dadgad Posted January 28, 2013 Share Posted January 28, 2013 Welcome to CADTutor. You would want to constrain the dividing line to the midpoints of the sides, if your intention were to stretch the rectangle perpendicular to the dividing line. Otherwise it would not be self centering, and would require an additional step to move it to the midpoint. When stretching along the axis of the dividing line, no problem, just select all three grips with a crossing window per JD's and Eldon's posts. Actually I wouldn't bother to constrain it, as it could be done more quickly in analog fashion, but since you asked. If you need this on a regular basis in your work, then creating a dynamic block would be the way to go. Quote Link to comment Share on other sites More sharing options...

Lee Mac Posted January 28, 2013 Share Posted January 28, 2013 If you constrain the three verticals using the symmetric constraint, you can stretch both sides simultaneously using either the STRETCH command or midpoint grips: Though, there are many ways to skin a cat in AutoCAD Quote Link to comment Share on other sites More sharing options...

Joelene Posted April 3, 2013 Share Posted April 3, 2013 Hi, Lee Mac, Can you tell me how to turn on midpoint grips just like yours on the screen? I am using Auto CAD 2009. Thank you. J. Quote Link to comment Share on other sites More sharing options...
JD Mather Posted April 3, 2013 Share Posted April 3, 2013 The example uses Geometry Constraints that didn't exist in r2009. Not sure if midpoint grips existed back then or not. If you click on a line you should get instant answer on that one. Quote Link to comment Share on other sites More sharing options...
SLW210 Posted April 4, 2013 Share Posted April 4, 2013 GRIPS=2 for midpoint grip on a PLINE, LINES should have a Midpoint Grip if GRIPS=1 or 2, if available in 2009. Quote Link to comment Share on other sites More sharing options...
ReMark Posted April 4, 2013 Share Posted April 4, 2013 Ralph Grabowski's book Using AutoCAD 2009 mentions the use of midpoint grips on page 464. Quote Link to comment Share on other sites More sharing options...

Joelene Posted April 4, 2013 Share Posted April 4, 2013 Thanks guys. SLO210: I tried the command GRIPS and the available value is either 0 or 1. And neither of them are for mid grip. I think JD Mather could be right. My coworker uses 2012 cad light and his shows the midpoint. But I will still look up the book that Remark mentioned. Thanks.

ReMark Posted April 4, 2013 Share Posted April 4, 2013 Could it be dependent on what command is being used? For example Stretch versus Move? A quick check using AutoCAD 2007. I drew a polyline and a line. I clicked on the line and three grips appear (both ends and the middle). I click on the polyline and grips only appear at each end. Could that be the case here Joelene?
