Hello everyone, I need to create a LISP file which will be used to draw a vertical profile for the pipeline system. Vertical profile should be created using a clicked point as datum and there should be an information section right under the profile giving information about the pipeline stations, slopes between them, diameter of the pipes, etc. I'm using an excel spreadsheet to create this pipeline system and all the information needed to create the profile is written in a .dat file. I'm not familiar to LISP creation at all, I only modified a couple of files shared by my colleagues. Here is what I need help with, I have a limited time to create this LISP file, so it is better to have a similar source code which I can modify it to work as I want. Anybody who have some sort of information about this topic or have some source codes willing to share, please help me out. If you think there is an introductory information that I can examine how command lines are working it would help me a lot as well.

The original would have been 1e-8 since all occurrences of "8)" were removed from all code posts across the forum when the forum software was "upgraded".

Plain autolisp should run fine on AutoCAD for Mac. Visual lisp and ActiveX functions, not. https://knowledge.autodesk.com/support/autocad-for-mac/learn-explore/caas/CloudHelp/cloudhelp/2019/ENU/AutoCAD-MAC-Customization/files/GUID-E6429154-36DF-4D84-8ABC-9FCA15B66158-htm.html

Took a moment lower case p is removed makes sense \\p in mtext. ^p in Word search replace not ^P

Change: ("$1" . "\\\\(\\\\[ACcFfHKkLlOopQTW])|\\\\[ACcFfHKkLlOopQTW][^\\\\;]*;|\\\\[ACcFfKkHLlOopQTW]") to: ("$1" . "\\\\(\\\\[ACcFfHKkLlOopQTW])|\\\\[ACcFfHKkLlOoQTW][^\\\\;]*;|\\\\[ACcFfKkHLlOoQTW]") And: ("\\$1$2$3" . "(\\\\[ACcFfHKkLlOoPpQSTW])|({)|(})") to: ("\\$1$2$3" . "(\\\\[ACcFfHKkLlOoPQSTW])|({)|(})")

Can you share with all of us what exactly you want? What exactly this .lsp does that you don't want, and what result you do want... ?

Maybe try StripMtext.

I don't understand that, unless I'm missing something. When a drawing is opened, the latest version of the xrefs are loaded, period, regardless of the setting you are referring to (which is the XLOADCTL sysvar).
