Title: check if block on surface
Post by: cadplayer on November 06, 2012, 10:13:04 AM

Hello all!

I have a simple question if it´s possible to check if a block is placed on a surface.
In a Civil drawing I have moved block to a surface according to [http://docs.autodesk.com/CIVIL/2010/ENU/AutoCAD%20Civil%202010%20User%20Documentation/index.html?url=WS1a9193826455f5ff1d61fe411049ed455e-6c52-procedure.htm,topicNumber=d0e77825]help[/url]I procedor the surface is changing but the blocks stay on old place. It would be nice if blocks could move dynamically.
Any suggestions?!

PS.: I don´t know how can formatting url better so I only comes for example "Link" and you can push the word

Only Labels are dynamically linked to a Surface.

Thanks for replaying, I have test it - very good. For understanding a label is a own Civil entity not a block, but can I convert a label in a block with attribut

If I look on a label entity I miss the value which stay in label (for example hight from a surface)

you can do away with this need if you insert your blocks through use of Points and Description keys.

what sort of blocks are you wanting to keep on the surface anyway?

Hi Michael!

What are you meaning with "Points and Description keys"

I have a block with a attribut which display high of insertpoint from surface. Type this ...

use points , random on surface instead

one needs to stop using autocad techniques where there is a tool within c3d that does the job better

Thanks but it´s the same result I get with slope labels  :oops:

your block appears to 'only' give surface elvation.
and why would one use a slope lable to get the surface elevation?


what exactly are you after?  Your posted block doesn't offer any clues?
