Rectangle Extend

[ejuander512]

Hello.

I'm a beginner who started AutoCAD. I need help with the Rectangle Extend.

I work in the structures department. I am currently doing a rough estimate of the quantity. based on the drawings provided by the architecture department. There is a limit to stretching hundreds of columns with Stretch because the positions of the columns are sometimes different. The Rectangle Extend Lisp provided by the user of the forum is very helpful when the position of the column is constant, but there is a limit when the position of the column is unbalanced. I wonder if it is possible to extend the girder to a column with a normal line and a polyline or block.

Please understand that the question is not clear.. because English is not my first language.

Thanks.

If the white rectangles are Polyline rectangles, you can at least do it without using explicit STRETCH commands.  Select the rectangle, and with PERpendicular Object Snap turned on, drag the midpoint grip of the end segment perpendicular to the appropriate edge of the column.

If that is still too cumbersome, what do you expect to be the steps the User would take?  Invoke the command, and then...?  Select hundreds of column rectangles and hundreds of the white rectangles all at once, and have the routine figure out which column to extend which rectangle to?  [I'm not seeing an obvious way for it to figure that out, but maybe there is a way.]  Select a column and the rectangles that should be extended to it together, separately from other columns?  Something else?

I see the column rectangles are not Polylines, but are made of four Lines, and they're on the same Layer as the wall linework, both of which will make the selection part more difficult, if you intend to select a lot of things at once.
