Hello!

Every time I use AutoCAD I have to connect electrical devices with a spline and then I need to draw a perpendicular segment (a line) to the already drawed spline in order to put a number indicating amount of cables.

I'm wondering if there is some way to create a new object, very similar to a spline in the sense that I can define any number of points to draw the spline; but with the additional feature of a "built-in" perpendicular segment.

Furthermore, I would need to be able to move this segment along the spline (after the spline points definition is done).  Perhaps the segment could have an initial position at the middle of the extension of the spline, but this is not really important as far as I can move the segment later.

Does anyone have any clue of how could I get this behaviour for a "personalized spline" (if possible).

Thanks!

I guess I didn't explain myself well enough.  I don't want to work in each spline instance, I would like to know if I can define a entirely new object (like a line, a polyline or a spline; this one would be named "mypoliline" or something like that)

Also, your advice didn't even result in what I need. Again, I always have to come up with a spline (of arbitrary number of points) and a short line perpendicular to the spline, in an arbitrary position along the spline.

I can do it easily in two steps, first draw the spline and then draw the short line. However, what I'm looking for is a way to do it in only one step: draw the spline and the perpendicular segment automagically appears there.

Thanks!

So, short answer is yes. Long answer: may be complicated, Lisp.

Thanks, I will start learning Lisp.

LOL, shoot for the moon!

Ok, I think I understand what you're trying to do. I'm not sure if I will be a complete help to you, but maybe I can at least get you pointed in the right direction here.

I think what you're looking to do is create a Dynamic Block. However, you can create a number of regular blocks and save them to your Tool Pallet so that you can quickly insert each one as you need it. This will at least prevent you from having to recreate the wheel every time you want a new item.

Here's a nice tip on working with Tool Pallets that I really love: au.autodesk.com/?nd=class&session_id=3071
