Drawing Parabolic curve in Autocad

Drawing Parabolic curve in Autocad

(OP)
can any one suggest tutorial links or materials for learning to draw parabolic curve in Autocad?

RE: Drawing Parabolic curve in Autocad

I'd probably use Excel or OpenOffice to create a list of points and import them.

RE: Drawing Parabolic curve in Autocad

Yes, that's what I would do. You create the X-Y coordinate points at intervals acceptable to you in Excel let's say in columns A&B. In row 1 - column D (or so) you write "_pline" and in the next row you do per attached. You can then fill all the other rows with the "Fill-down" command in one fell swoop. Then you put column "D" to the clipboard and subsequently into a text editor and save the file as e.g. Parabola.scr. Finally you insert this polyline into your drawing with the "Run Script" command.

I'll try that for a catenary... thanks.

Another way to get the points coordinates from Excel to AutoCAD is to just copy and paste.
In AutoCAD start the "pline" command, copy the range with x,y points from Excel, paste into AutoCAD's command line. You may need an "enter" to end the command.

RE: Drawing Parabolic curve in Autocad

Oh, I forgot to say to turn "Object Snap" off when you do that otherwise it might create a mess.

RE: Drawing Parabolic curve in Autocad

You probably don't need very many points.
I would guess no more than 5.
If you use more than that - post your example here.

Or you could make an auto lisp macro.

You could Slice a cone.
