String with Getenv

[mwade93]

I have been playing around with these variables, I have not been able to figure out a way to make a string with getenv embedded in the string. For example Rev(X)-Date. Is there a way to prompt the user for just the number (X) with setenv/getenv?

[mwade93]

I actually answered my own question.

 

It just looks like this:

^C^C^C-la;t;rev$M=$(getenv,users1);;

 

I just have to set users1 before I issue this button.

I have a stupid question. I never used the user variables before and always wrote my macro's around them. How do you set the user variables?

[mwade93]

I used setenv then entered users1 and prompted the user for the answer:

 

^C^C^Csetenv;users1;\

 

I know there is a users2 variable but I can't seem to get it to work.

[Tuns]

Thanks for the info. I'll probably use that in some upcoming macro's. Why do you have 3 escapes? You only need 2 at most.

[mwade93]

I always use 3 just to make sure. That is a habit I picked up from my instructor I had in the customizing class.

 

How do you normally do your diesel macros then if you don't store anything?

Does this work for you, all in one,

 
^C^C^Csetenv;users1;\-la;t;rev$M=$(getenv,users1);;

I use the magic of variables already present in the drawing. For the most part I don't really need to store variables for my job.

That would work except I have 3 other items related to the desired level so I don't want to prompt each and every time. I prompt once then the other buttons do not prompt.

The variables never work when I try to use the default system ones.

Could you explain a bit more, it sounds interesting.

Here is the toolbar. The first button sets the level by prompting the user. Next draws a rev cloud on the revX layer. Next one inserts delta with correct number. Last one changes the date on the title block.

Well, for example, if I try to insert the variable dimscale into a macro, it always gives me 1. Basically, it always give me the default system variable as if the value for each variable has never been changed.

I know there is a users2 variable but I can't seem to get it to work.

 

The reason you are having trouble with the USERS2 variable is because there are no USERSn variables in LT, just in full AutoCAD. The S stands for a string value. There are USERRn where the R stands for a real value and USERIn where the I stands for an integer value.

 

Here is an extract from the LT User Guide > Command Reference > System Variables:

 

 

• UOSNAP
  Determines whether object snapping is active for geometry in DWF, DWFx, PDF, and DGN underlays that are attached to the drawing.
   
  
• UPDATETHUMBNAIL
  Controls updating of the thumbnail previews for views and layouts.
   
  
• USERI1-5
  Provides storage and retrieval of integer values.
   
  
• USERNAME
  Specifies the user name.
   
  
• USERR1-5
  Provides storage and retrieval of real numbers.

I have read that you can use the variable "strPrefix", but I have no other knowledge on that and I can find no reference to it in the documentation.

Tyke, you are a king. You just solved a world of confusion for me.

[mwade93]

Thank You, that makes sense. Makes it a little less confusing to dumb down my cutomizing

[steven-g]

DUH! I didn't even spot that you where using getenv and talking about system variables, the click just didn't happen.

[mwade93]

No problem, I would love to be able to use the system vars but they stuck me with LT.

[Tuns]

You still can use system variables, just not the string variables. Unless that's what you meant.

[steven-g]

Hey don't get me wrong you can use them, but it's 'getvar' and 'setvar' that you want. And not 'getenv' and 'setenv' which is a different animal, that's why setenv users1 worked, basically the differenece is that getenv reads variables stored in the windows registery and can have just about any name you choose, and it is available to every drawing, anytime you want until you change that value with setenv, whereas getvar is what you use, to find the variables within the current drawing, and those values are reset for a new drawing to the default values.

PS it is the use of getenv/setenv that lets you use strings in variables in LT, but a word of caution setenv will create variables in the registry and they stay there for ever so try and use them sparingly or use the same name each time unless it is something that has a special purpose.

[Tuns]

That in itself is a landmine almost like x-ref's. If your not paying careful attention you can make a huge mistake.

[steven-g]

It's not so much a question of mistakes, just something to be aware of, a lot of people don't consider that setenv creates something permanent, so if you are happily using setenv in a macro and the name uses todays date you could end up very quickly with hundreds if not thousands of system variables wasting resources, If the intention is to count how many drawings you have created in a project then fine, but if it's just for a temporary store then get into the habit of using something like temp1, temp2 and stick to that.
