Hi guys, I would need to create a lisp that allows me scale object only in one direction (X/Y).
Only option I found in AutoCAD default, is create block and in properties change scale factor X, Y and after that explode block.
My idea is create tool similar like "Align" command but scale object only in one direction, not uniformly.
It would be great if lisp automatically recognized in which direction objects scale by selected reference points.
Is possible create something like this?
Thank you.
In addition to @paullimapa 's link, you will find a number of scale-in-one-direction routines with some Searching, but I believe all of them will do it by way of a temporary Block to change the scale factors of, and I don't know that any of them will do everything you want, particularly recognize which axis you want to scale by the points you pick. But maybe....
But if you're starting with something at scale factors of 1, it's easy enough to just Scale it normally to get the size in the direction you want as you want it, and then in Properties just set the other axes' scale factors back to 1.
I hope you realize that in your example, after such a procedure [however you accomplish it], the widths of the vertical and horizontal frame members will no longer be equal, and the widths of the curved members [assuming you're curving a metal rod or something] will no longer be constant.
Well it's not so easy. In this example I use it for scaling individual parts of railing around arc in perspective in elevation view. But vertical bars are scaling too but in different ratio than horizontally parts etc. It's quite dificuilt and time consuming do it acurrate in 2D. Cause of that I looking for lisp, that alows me quick scale selcted object in only one direction without manualy creating block before. I understand it won't be 100% accurate, but best ratio time/accurate.
Model a segment of it in 3D. Then set the UCS so you can do a polar Array of them, and the elements will all be the right size from all variable oblique angles they are viewed from. You can leave it in 3D, or Flatten the completed arrangement into 2D if you want.
If you draw an arc then can do facets that are the width of the frames then work out the X values x1-x2 so it will reveal the scale for you. An example attached can change to use chord distance say from center of arc.
Well it's not about only fence, but all stuff whith aren't parallel with the elevation view, at some angle or around arc (doors, windows, roofs, stairs, ornaments on walls,..)
Cause of that I want lisp for quick scale lot of stuff individually.
I thought little bit more about that, and I got this :

I'm guessing that has everything to do with where the insertion point is in the Block. One of your images looks like it's at the top of the left post element. It should be at some place on the Block that is on one of those green reference lines.
