Hi folks. Have been trying to make s lisp code for a simple task but turned out that it might not be so easy. I found lots of information but not this one. So i'm asking if this is even possible to do. I have a block and it has many entities. The block has a name but all the (2-3) entities have different color. I'm trying to change the entity color without exploding the block and change the entity name. This part is ok and i even found a good solution for this. However the problem is that i have to rename also the main block regarding the selected color for the entity. I have 5-10 options for color. (112=blue, 113=red etc.) So the final block name should turn out as 123456-112. I know how to find the block name and change but when i go deep into entities then i dont have the DXF code for the original block name. So here i am in an endless loop. Can someone assist or show me some directions how to manage with this? Thanks.
hello, I inherited a title block from someone else in the company and it is loaded with perhaps 20 MB of invisible content. I have done the following without success to reduce the file size: Purged many times. There are blocks which won't purge because they may be nested or for some other reason. I have deleted the dwg bit by bit to check the file size - it remained big, even with nothing visible. I have checked all the layers for any possible content - zoomed to extents and deleted everything on all layers. I believe the problem lies with blocks from previous projects nested inside the drawing which won't delete. Purging won't allow ne to delete nested or x-referenced blocks. Any other suggestions, please!
