Topic: Background grid with LISP

[keithsCADservices]

I've found how to edit most settings, but not the background grid. Most searches lead me to table gridlines. Is it possible?

I'm trying to find a way around the lack of having profiles available in ACAD LT.

Explain more if you want like road profiles then LT will not help. yeah LT 2024 has lisp but I would go Bricscad and Civil Site Design you will get so much more out of it.

BIGAL: I think you replied to the wrong topic.

I have tried BricsCAD however. And quite extensively. It didn't work that well for me unfortunately. Hence why I pay for AutoCAD every year .

[BIGAL]

Think I understand now your talking about Options, Profiles, save/load as ARG file etc. the /P switch in the start up.

If correct there may be a way around the problem.

The default grid color with a black background looks pretty okay. But when I switch to a white/off-white background, it looks not great. Some workflow(s) having me switching from one to another.

I realize that I can't access several other settings as well. And only a few things are accessible (crosshair color, etc...) so it might be a lost cause.

As of now I'm pondering two separate installs.

Buried away in the registry is stuff like set this color, the problem is finding the value to change and even if you do the value, its often like 172356.

I have changed values and yes worked but you have to be super careful playing with the registry. Plain LT does not support the lisp (setenv which will reset registry.

Thanks BIGAL! "setenv" is the key to winning on this.

The good thing is that I can simply grab the numbers once I set my grid(s) the the desired numbers. This should also prevent damaging the registry? There will be no options for example, for a user to pick their own colors.

I did see someone post a way to convert colors from RGB to these numbers. I'll post that if I come across it. I won't need it though.

This is how I'll get my colors:

Command: (getenv "2D Model grid major lines color")
"6901577"
Command: (getenv "2D Model grid minor lines color")
"4732722"

Setenv will also help me access a few of the other settings I need.

This link demonstrates setenv in a similar way to what I'll be using it for:

Thanks so much BIGAL.

Lee-mac.com has a work out color numbers has various output functions.

Command: (getenv "2D Model grid major lines color")
"6901577"
Command: (getenv "2D Model grid minor lines color")
"4732722"

They look to be OLE colours - you can test this using my OLE->True conversion function and the following code:

Code - Auto/Visual Lisp: [Select]

1. ((lambda ( c ) (entmake (list '(0 . "LINE") '(10 0 0 0) '(11 10 0 0) (cons 420 c)))) (LM:ole->true (atoi (getenv "2D Model grid minor lines color"))))
