When defining a macro, how to represent a SHIFT key stroke

[brucejwangtaiwan]

Hello,

With interactive manipulation, I can Ctrl+A, then Shift, then use mouse to specify a rectangular area, then Del to erase everything outside the rectangular area. I must use Ctrl+A instead of Select command because Ctrl+A can pick up unseen objects which Select All can not.

Now that I want to make the serial manipulation into a macro. I found Ctrl+A to be ai_selall but how to represent Shift key stroke in a macro?

Regards,

You are correct that Select All will not select Unseen objects.

But the following WILL.  This is technically AutoLISP code but that doesn't prohibit you from using it in a macro or script (you could just as easily type it at the command line).  This will select EVERYTHING in the current dwg file regardless of what "space" it's in -- Model Space, Paperspace and All layout tabs.

(ssget "x")

Hi Don,

I then want to specify a rectangular area with lower left coner at 0,0 and upper right coner at 841,594, then delete everything (ssget "x") picks up but only outside that rectangular.

How to write such a macro?

Thanks,

Bruce

I think you're better off doing this with an AutoLISP routine.

Go to afralisp.net and search for ssget. There are LOTS of helpful options. I would have it create two selection sets. One using the X option and the other by window selection (if memory serves, you're looking for W instead of X). Now run (command "e" entsel1 "r" entsel2 "" ).

That will start the erase command, select everything from the X option then REMOVE everything picked up in the W option.

Note: the following will store your ssget selections in the appropriate variables.

(Setq entsel1 (ssget "X"))
