Hi all, If I edit a block definition in one file, is it possible to update all instances of the block in another file? I have tried to insert my updated block definition into another file where the block is used multiple times, but it just inserts it as the old definition in that drawing. Can I redefine the block and replace all instances of it with the new updated version? trying to find a productive workflow that doesn't make me want to pull my hair out! thanks in advance. SC

Hi there, So my job would like me to create a usable library of products to make things easier. We make custom cabinetry, but there are many more standard sizes that may be useful. I'm vaguely familiar with creating blocks and saving, but I'm trying to find out if there is a good way to go about making this library since the sizes will need to be changed often. Is it even worth creating such a library? Is there an easy way to temporarily edit blocks to make them a few inches bigger or smaller? I've been using AutoCAD technically for years, but it's been very on and off, and I learned on my own so I don't know all the correct ways to go about things. Help?

Right now I have 15,000 drawings that use letters instead of symbols, an artifact of a now defunct CAD software that translated the letters into symbols. I'd like to remake this in AutoCAD by inserting blocks at the location of those letters. I cannot find instructions on how to do this anywhere, and I need to add the following things to my code: 1 - Insert a set of blocks from another drawing. 2 - Select a specific letter from text in a specific layer in code 3 - Insert one of the newly inserted blocks at the insertion point of the letter 4 - Delete the character as it is no longer needed (unless it was replaced, then it wouldn't be there anymore) Example: Import set of blocks from template drawing. Select from layer "Curb Valve" the character "R" from a piece of text in the layer (exact match preferred if possible). Replace this symbol with a block named "CurbValve." I know you can get the X,Y of the text letter and manually type that in when you manually insert a block, so if you can detect this somehow and assign it to a variable, then use that variable to use as the insertion point of the block it would work. I just haven't been able to figure out how to do it programmatically. Thank You!

Hi, I am looking for LISP application that can do the following: 1. Manage a Library of Blocks (the blocks can be of two types: a drawing with numerous blocks or a folder with each block written to a dwg file) 2. Open a Block and turn first-level elements color and linetype to BYBLOCK Thanks you in advance.
