AutoCAD LT 2006 - add "IF" logic to Floating Viewport macros

[Paul Munford]

I am currently having lots of fun designing new command buttons for my fellow draughters. So far they've been pretty simple * , but I'd like to make them more complicated. I am new to Diesel and could use someone to bounce ideas off...

These two macro's spin the view in the viewport by 90 degrees left and right.

^C^C_UCS;Z;270;PLAN;; - CLOCKWISE

^C^C_UCS;Z;;PLAN;; - ANTICLOCKWISE


This is cool, but could be better...

For example, if the viewport is locked the UCS continues to spin. Also if you are not in a viewport the UCS continues to spin round... Not necessarily a problem, but could be inconvenient.


I have a feeling I can solve both of these issues by using an 'IF' statement and getvars. I don't really understand the format that an 'IF' statement takes, i.e which part of the formular is doing what. Could any one 'lead me through' it, or point to a good tutorial?

Cheers - in advance...

* The Macro's - not the draughters...

Here is sample IF for you:

$M=$(if,$(=,$(getvar,tilemode),1),TRUE,FALSE)

The portion in orange is the test (IF "tilemode" equals 1). If the test is true it does the first statement, if the test is false it does the second statement. Each statement is separated by a comma.

Thanks Ty, That's a good start. I will take this away and have a play with it...
