AutoCAD - Questions about Dynamic Input

mbloswick — Tue, 20 Sep 2022 15:14:46 GMT

I have a couple of questions about Dynamic input. I find it very useful, but there are a few functions I'd like to know about, if they exist.

First, is there any way to switch it from distance/angle to deltaX/deltaY? I often know how far "over and up" I am drawing, but I rarely know what angle that would be.

Also, is it possible for dynamic input (or any location input) to use calculations as a distance? For example, if I want to draw a line sloping downward at 2%, that line (in XY input) is @ 11, 11*-0.02. I can do this easily in other software...I have seen posts that say "Using LISP, you can enter values computed as mathematical expressions - at almost any prompt in AutoCAD" but it doesn't appear to be working. As in @Anonymous,(* 11 -0.02) doesn't give me the line I want. It doesn't seem to work in the Dynamic input, either as in 11,(- 180 1.1458) as distance/angle

Is there any other way to draw lines at a slope (not an angle)?
Thank you.

While you wait... here is an overview on how to use the 'CAL function at the commandline for when you need to add "mathematical expressions" https://www.javatpoint.com/autocad-started-with-cal-command (scroll own about a 1/3 of the way to the title "Calculations using CAL on command line")

That looks as if it can get me most of what I'm looking for. Thank you.

When you draw a slope line, instead of using command LINE, you can try command RAY.

For example, to draw a line at 0.02 (2%) slope, you can try this:

Interesting. I've never even thought of using a ray. Actually, I've never used a ray for anything, so I'll have to look them up to see how they work. That would cover what I need. Thank you!
