Label points X,Y,Z

February 17, 2016

Dear all;

My end goal is to find a Lisp that will Auto-Labels X,Y,Z when u select points as shown Image Label Mtext with leader without overlapping

Thanks in advance for any help/advice

Alternate suggestion:

1. Create dynamic block, with reporting XYZ coordinates

2. Insert that block ontop of the pointslist

February 17, 2016

Create an attributed block with attribute values containing fields referencing the block insertion point.

You can then use my Point Manager program to insert such block at all points in a selection.

Oh yeah, I completely forgot about Lee's Point Manager - people who are labeling XYZ coordinates won't imagine living without it.

Many thanks Lee Mac for your suggestion to my thread

& thank Grrr

See you again

Dear Marko_Ribar

I was much more busy with my work couldn't get time

Thanks, worked perfectly.

You have to redefine block DWG I posted... Just change position of attributes with fields - I think you can do this through command BEDIT.

Just a comment all our civil projects are labelled with a pt number rather than a xyz, the reason for this is very simple that you upload it into a survey data collector so you can set it out. We normally create a table with the XYZ details and description. This is built into CIV3d but we still have the old routines that create the point adjusting pt number export to a csv and reimport into a table.

I did the same but error message appears, again I look into your program I find that I should not change the cad file name, once again I will try........

Sorry, it's been a while since I created that DWG... It was fields inside MTEXT - not attributes... Try with this DWG...
