how to plot x,y,z coordinates using autocad VB...can someone give me the script plss
email me at email@example.com or add me as ur friend using yahoo massenger
When you saywhat do you mean exactly?plot x,y,z coordinates
print coordinates of certain objects to external files? i.e. coords of points to text or excel files...
Could you please explain further
I assumed the OP wanted a plot window.
I didn't reply as I didn't have an answer but I did manage to stop myself posting saying answers should be posted in forum. Now you've done that I can agree.

This is my first post and it may or may not be what you're after. I suggest you read and try to understand the code as my error handling here is not the best. I have a user form for picking the file and blocks (which are passed to the routines below) but I can't see how to attach anything here.
The following code will place blocks at coordinates read from a csv text file (x,y,z,name or x,y,name - your could change the column order easily if you wanted, I just haven't got around to it). The 'name' will be placed if the specified block has an attribute.
The block you want to use must exist within the dwg.
The file format is a csv file of either 4 columns (x,y,z,name) or 3 columns(x,y,name).
Make sure no coordinates are missing.
For 'x,y,name' a z value of 0 is assumed.
