Dyanmic Block and Lisp

It's me again with another question.

I'm writing a lisp that inserts a block and if you choose you can tag it with a leader which has another block w/ attribute text automatically filled in. The block with the attribute text is a simple dynamic block with 1 extra point for insertion. so when you get to the point of inserting the attribute block you can just press *CTRL* to cycle through the to insertion points which are right or left.

what I would like to do in my lisp is define which side to use. Here is my logic.

P1(x1,y1) is the insertion point of the block to be detailed.

P2(x2,y2) is the point of my leader landing

if x2 >= x1 then use right side (original insertion point), else use left side (2nd point defind by dynamic block)

the first part is easy. i'll just use P2 as the point to insert. it's the 2nd option. I need to tell autocad to first use the 2nd point as insertion point, then insert it at P2. Is this possible?

I suppose I could make 2 blocks, one with right side insert and one with left side. I'd rather have one but if I need 2 i will.

lol that's F****** awesome. now i tried to look up some of the commands you used but they are not listed in the acad help files. Like vla-insertblock. it's not listed. where can I get a list of these commands.

where can I get a list of these commands.

Look in the help ActiveX and VBA Reference

As a rule for Lisp

method -> vla-method

property -> vla-put\get-property

Haha glad you like it

As GeoBuilder says, type vla-insertblock in the VLIDE and double-click on it to highlight the whole word, then click on the help icon.

This may give you some insight:

http://www.cadtutor.net/forum/showpost.php?p=258403&postcount=9

double-click on it to highlight the whole word, then click on the help icon.

As, instead of "сick on the " after highlight the whole word, it is possible Ctrl+F1

or...

while on the vlide editor

- click on the apropos options (A)

- type the name of the function or the first letter like vla- vlax- etc... or use the available search options

- and highlight under apropos results the function name

- and click on the help icon

there are some functions left over from the original vital lisp, like vlax-get, vlax-put, etc.... that are now undocumented
