Hi,
It's not that easy to do these changes in LT version, but my idea might help you in saving some time(as it did for me in the past) before someone come up with a best solution.
As you have not uploaded the drawing file, as per the pictures I understood that the Text “NAME” needs to be replaced with “PROJECT NAME (ADDRESS, COORDINATES)” and this should be scaled to fit in the rectangle box. I hope the block names are same in all 500 projects.
As shown in the attached picture, use the FIND command to replace the text in all the blocks. That is part 1.
Now you need to do some inventory to find the base point and best scale factor to adjust the text to fit in the rectangle box in the block, based on the insertion point of the Blocks this should be same for all blocks, note the XY coordinates and scale factor.
Now in the below macro, change the BLOCK1 to the block name you want and change the XY coordinates 0.5,0.5 to the one you find in above step and change the 0.25 to the scale factor you find in the above step.
^C^C-BEDIT;BLOCK1;SCALE;\;0.5,0.5;0.25;BSAVE;BCLOSE;
Then add this macro in the tool palette and run, you need to select the Project name text then rest will be done by this macro. Add as many macros as you want by changing the block names.
Or add one macro for all blocks like below, everytime you need to select the TEXT. Make sure the block is present in the drawing and check the locked layers.
^C^C-BEDIT;BLOCK1;SCALE;\;0.5,0.5;0.25;BSAVE;BCLOSE;-BEDIT;BLOCK2;SCALE;\;0.5,0.5;0.25;BSAVE;BCLOSE;-BEDIT;BLOCK3;SCALE;\;0.5,0.5;0.25;BSAVE;BCLOSE;
