I've tried searching this but have yet to find something that suits anything close to my needs. I'm trying to create a Autocad LISP that takes a text file, which is a list of comma-separated values, and place a block at coordinates defined by the list. BUT, only for items on the list where the last entry starts with "HP"
So that's sounds a bit complex, but the text file is basically a UTM survey output, and looks like this:
1000,Easting,Northing,Elevation,Identifier 1001,Easting,Northing,Elevation,Identifier
Etc.
The identifier is a variety of values, but I want to extract the Northing,Easting,Elevation, and insert a block (this last part I've got) at that location when the identifier begins with "HP". The list can be long and the number of HPs can be 1 or 5000. I'm assuming there's a "for x=1:end, do" type of loop than can be made that reuses the same variables over and over.
I'm a newbie to LISP so I'm stuck in that spot between "here are I've-never-programmed-before tutorials to make hello world" and "here is a library of the 3000 different commands in alphabetical order"
