stevsmith Posted January 20, 2010 Share Posted January 20, 2010 When you create a block it gives you an option to allow exploding. Maybe this was not checked when the block was made. If you want the exploded objects, go into the block editor and copy the items and place them into a new drawing. Quote Link to comment Share on other sites More sharing options...

I know this option but what make me crazy that the block name didn't appear in the drop down list which show all blocks names thank you for your reply Quote Link to comment Share on other sites More sharing options...
dbroada Posted January 20, 2010 Share Posted January 20, 2010 an anonymous block. They are a bit tricky. I don't have time to search so I'll let you. Search this forum on anonymous blocks and you will find lots of advice. I can't remember if they can be manipulated or not thoough...

eldon Posted January 20, 2010 Share Posted January 20, 2010 Having downloaded your drawing and tried Explode, I am puzzled by the thread title, because the object exploded without any bother. What am I missing Quote Link to comment Share on other sites More sharing options...

What am I missing a new version of AutoCAD? I couldn't explode it here. Quote Link to comment Share on other sites More sharing options...
dbroada Posted January 20, 2010 Share Posted January 20, 2010 From Super Moderator rkmcswain. http://rkmcswain.blogspot.com/2005/09/cannot-explode-block.html Mark, that is for blocks created as unexplodable. This is an anonymous block that can't be selected with BEDIT or BLOCK. Quote Link to comment Share on other sites More sharing options...
eldon Posted January 20, 2010 Share Posted January 20, 2010 OK, so I am a stick in the mud, but I did use r2005 when I exploded it Quote Link to comment Share on other sites More sharing options...
ReMark Posted January 20, 2010 Share Posted January 20, 2010 Since the block's single attribute can be editted why is it necessary to explode the block? Quote Link to comment Share on other sites More sharing options...
dbroada Posted January 20, 2010 Share Posted January 20, 2010 Since the block's single attribute can be editted why is it necessary to explode the block? that's a different question and one I didn't think of asking Quote Link to comment Share on other sites More sharing options...
ReMark Posted January 20, 2010 Share Posted January 20, 2010 OK Dave, OK. I'm uninstalling 2010 and reinstalling 2005 since I was unable, by normal means, to explode what appears to be an anonymous block (*U1). It did not show up when using the BEDIT or BLOCK commands. So I did the next best thing. I searched for and found a lisp routine that renamed the anonymous block from *U1 to Temp1 and then I was able to explode it and I also was able to edit it using the BEDIT command. So there. Nah, nah, nah, nah, nah. Quote Link to comment Share on other sites More sharing options...
FATHY Posted January 20, 2010 Author Share Posted January 20, 2010 I found the solution of this problem in a link that I can't attached due to no. of posts less than 9 this done by using autolisp and its content Anonymous Blocks in AutoCAD From Draftsperson.net Written By Allan using AutoCAD 2004 "AutoCAD uses anonymous blocks for supporting hatch patterns and dimensions. These types of blocks are also created using AutoLISP or similar means, but cannot be intentionally created in the drawing editor. Also, anonymous blocks cannot be modified using AutoCAD editing commands." - What are the Types *U### = anonymous blocks *E### = anonymous non-uniformly scaled blocks *X### = anonymous hatches *D### = anonymous dimensions *A### = anonymous groups Converting Anonymous Blocks to Normal Blocks For the the purpose of this discussion the block in question is named *U105. 1. RENAME *U105 to U105 (still an anonymous block, but now will appear in the BLOCKREPLACE drop down box) 2. Create a matching block to replace U105. We will call this block COLUMN 3. Use BLOCKREPLACE to replace U105 with COLUMN Exploding Anonymous Blocks *U### uniformly scaled blocks can be exploded with the EXPLODE command. "When nonuniformly scaled blocks contain objects that cannot be exploded, they are collected into an anonymous block (named with a "*E" prefix) and referenced with the nonuniform scaling. If all the objects in such a block cannot be exploded, the selected block reference will not be exploded. Body, 3D Solid, and Region entities in a nonuniformly scaled block cannot be exploded." - AutoCAD 2004 Help File LISP Routine for Converting Anonymous Blocks to Normal Blocks this lisp solve the problem Unanon.lsp Quote Link to comment Share on other sites More sharing options...
ReMark Posted January 20, 2010 Share Posted January 20, 2010 ^ ^ ^ ^ ^ That's the solution I used too! Here is the link to the actual webpage depicted above. http://www.draftsperson.net/index.php?title=Anonymous_Blocks_in_AutoCAD Quote Link to comment Share on other sites More sharing options...
