Re-define a blocks insertion point with out changing the entire drawing?

[rbhazie]

I have a master drawing with a ton of electrical blocks that have the insertion point in the wrong location.
How do I modify the block to have the correct insertion point with out redoing the entire master drawing?

I believe you'll have to edit the master drawing, use BEDIT to redefine the insertion points for the block definitions you want to change. Close BEDIT, and save the drwing.

After that the question is _how_ do you use the blocks that are stored in the master.... there are several options

[Ed Jobe]

Once in BEDIT, you'll either have to move the entities in relation to 0,0 ( the basepoint) or run the BASE command and change the basepoint from 0,0.

Thanks, I was just going to go into the block editor and re set the base point to the center of the object. But then that will change all the blocks ini the drawing and they will no longer be in the correct location.

I may be misunderstanding your use of the term 'master drawing'. I interpreted that to be a library drawing, from which block were inserted into working drawings. It's starting to sound like your 'master drawing' is in fact a working drawing?

If you redefine the block insertion point, then yes, they insertions will "move". You can filter for that block name and move them back.

[rbhazie]

Yes this is a working drawing with a very large amount of incorrect blocks. To change the insertion point would destroy the entire drawing. Was looking for a way to make the change without have to re build the entire drawing. Not looking to good.

One possibility, presuming that all the blocks of the same name are at the same insertion scale.

Keep track of the distance you move the objects in BE to get them on 0,0 as the correct insertion point. Then after redefining and saving the block, use the FILTER command to select all of those blocks by name, and move them the opposite distance * insertion scale

... use the FILTER command to select all of those blocks by name....


I've always found QSELECT Command to be more useful.

At the risk of suggesting a different workflow... One could instead simply change the block's base point, and retain it's current position with something like Lee's Change Block Base Point (http://www.lee-mac.com/changeblockinsertion.html) routine:

That sounds like exactly what the OP does want. :)

This worked out fantastic, Thanks so much for all the help.

I'm sure Lee would be pleased to know that... You're very welcome, rbhazie; I'm happy to help.

Cheers
