# Z Coordinate, moving all objects to 0 with space defined.

## Recommended Posts

Hello to all,

I'm back needing a help again, I have one "challenge" (problem! He he he...) that consist in get every object that has on a specific coordinate Z (plan), and I need to take every item of this plan moving it to Z=0, but, I have 200 plans with 6 objects each one, moving it to Z=0 it will be one above other, It's necessary move it in coordinate X with a specific space (one item to be filled up).

I'll be grateful if someone knows a Lisp that could help!...

I found something that could help me, but someone knows how I can get all objects at same plane to move it together? It's that missing to finish the code!

The code that I'd found... so doesn't work moving on X position... It's working good, but, entities are overlapping!... In red I make a simple way to move the objects... level by level... modifying the 5000 value... I can do it incremente it by level or by a input number to be filled up by the user.

If someone could help me... thanks in advance...

Wowwww... You did the most hardly... separating the slices in new drawings... It's it Marko, are working!... Thank you again!... But, It's possible get the slices and put it on Z=0 on the same Model Space?... Spacing them by levels origin?... Objects on Z=10, goes to X=0 and Z=0, the next level Z=20 goes to X=5000 and Z=0, next level Z=30 goes to X=1000 and Z=0... until all levels are done?...

I decided to space them using DX value of all sel. set of entities added with gap between them... Have you tried "Yes" option when asked for scatter?

BTW. I've changed code little more to check if entities are 2D - if not program quits and also quits if entities aren't parallel to WCS...

Ok, thanks again Marko!... It's exactly that!... I saw that you use a external reference to put them side by side, I'm use it on the same Model Space to work with it, It's necessary to get the entity, explode, cut, and a lot of other things to do... On these way I need to use a Refedit, subtract from external reference (REFSET - remove from working set) all of them to can work, it's possible to do in another way? So, even this way, you save me a lot of time making this code and avoiding mistakes!!!... I'm realy greatful to you!!!...

Once new file is generated with XREFs, you can simply do XREF command, select all XREFs and bind them... If you want to loose layer info that is to make it like in orig. DWG, when binding, use INSERT option and after that EXPLODE on created blocks... But if you want to keep layer prefixes obtained from XREFs, for ex. (dwgname-0.00000000\$0\$Layer1) you should use BIND option and then EXPLODE created blocks from XREFs... Of course 0 Layer will remain 0 in both cases, so it's strongly recommended to create new layers and put entities on them before (c:elevs2xrefs)...

Master Marko!... Thank you!!!... I was testing it, and works as good as I expect!!!... By the way, Its possible insert one text like "Z=position" on Xrefs tops? I got one doubt, inserting a space to Scatter (as example = 5000) it space the slices on 8633.2363 looking the code I didnt found why it's happening, I saw that has a "+ dx gap" could be "dx"?
