RFRUSSO Posted May 15, 2007 Share Posted May 15, 2007 I have a North Arrow that I would love to make into a dynamic block. I would like to be able to rotate the N that represents where the north direction is. But while rotating the N around the center of a circle I would like the letter itself to stay un-rotated. It seems simple, if I rotate the letter around the axis of a circle 90 deg, I would like the letter itself to rotate -90 deg on it's own axis. Of course this is easy to do manualy, but how do i do it so that rotation 1 automaticaly triggers rotation 2? Quote Link to comment Share on other sites More sharing options...
Cad64 Posted May 15, 2007 Share Posted May 15, 2007 Take a look at these video tutorials, they are very helpful: http://www.cadclips.com/Acad2006-DynamicBlocks.htm Quote Link to comment Share on other sites More sharing options...
RFRUSSO Posted May 15, 2007 Author Share Posted May 15, 2007 Those are great videos. I have watched them all when i first started working with CAD 2006. They don't cover what I am trying to do. I was hoping that some one here would know if it could be done and if so how to do it. Quote Link to comment Share on other sites More sharing options...
Cad64 Posted May 16, 2007 Share Posted May 16, 2007 I've been trying, but I can't find a way to make the "N" spin as it's being rotated around the circle. Quote Link to comment Share on other sites More sharing options...
dbroada Posted May 16, 2007 Share Posted May 16, 2007 I thought that I had done this in the past but I can't get it to work now. either. I was convinced that I rotated the text at angle * -1 but that no longer works. I also tried moving the text but had nothing to tie it to.

dbroada Posted May 16, 2007 Share Posted May 16, 2007 this works if you only rotate orthogonally! We need a way of rotating the letter AGAINST the other angle. This rotates with and subsequently rotates twice as fast as the circle. Quote Link to comment Share on other sites More sharing options...
dbroada Posted May 16, 2007 Share Posted May 16, 2007 got it!!!!!! now where's the SMUG smillie? NorthArrw2.dwg Quote Link to comment Share on other sites More sharing options...
Cad64 Posted May 16, 2007 Share Posted May 16, 2007 Hmmm, can't seem to get the drawing to work. When I click on the link, the drawing opens in the block editor. Then when I close out of the editor, the drawing closes. I get a message stating "the drawing contains authoring elements, open in block editor?" If I click "Yes," the drawing opens in the block editor, if I click "No" the drawing opens without any dynamic properties. Quote Link to comment Share on other sites More sharing options...
dbroada Posted May 16, 2007 Share Posted May 16, 2007 Oh. Instead of opening it, save it and then INSERT into your drawing. I drew it in metric so may be an odd scale! Quote Link to comment Share on other sites More sharing options...
Cad64 Posted May 16, 2007 Share Posted May 16, 2007 Nice one, you get a gold star for that Quote Link to comment Share on other sites More sharing options...
dbroada Posted May 16, 2007 Share Posted May 16, 2007 Nice one, you get a gold star for that Thanks. I've waited most of the morning for somebody to ask me how its done. so I'll tell anyway. I excluded the "N" from the rotate selection set but have added a Point Parameter at its insert point. There is a Move action associated with the Point parameter and a Chain action on the Point. When the rotation is applied all but the N rotate and the chain action on the point instigates a move. I have made a couple of cosmetic changes since I posted this but in essence it's much the same. I feel so smug! Quote Link to comment Share on other sites More sharing options...
RFRUSSO Posted May 16, 2007 Author Share Posted May 16, 2007 You are a rock star my friend! This is a great block. I was so hung up on trying to figure out how to get the N to have some sort of negative rotation value, I never even considered using any of the other options. I was a slave to the box. I am going to use this as a reference to build my own to see if I can build a similar block that is as clean and sharp as yours. Thank you.

AJSatGLS Posted January 14, 2010 Share Posted January 14, 2010 I know this is an old thread, but I just had to tap in and say that that really is a great block! Thanks for the help!!! Quote Link to comment Share on other sites More sharing options...
MrJackson Posted February 11, 2010 Share Posted February 11, 2010 Awesome block/how-to, exactly what I needed for a similar block. Quote Link to comment Share on other sites More sharing options...
BelCAD Posted July 1, 2011 Share Posted July 1, 2011 Been looking a long time for this one and yes... here it is, you don't know how this makes my life easier! Thx alot for sharing!! Quote Link to comment Share on other sites More sharing options...
dbroada Posted July 1, 2011 Share Posted July 1, 2011 I was looking for this thread a few weeks ago and could I find it? Of course not. At least I remembered what I did and managed to replicate it. Thanks for the thanks. Quote Link to comment Share on other sites More sharing options...
BelCAD Posted July 4, 2011 Share Posted July 4, 2011 Just one small thing going wrong. In "test block" everything is fine and working like it should, but when saved and used in a drawing, the attribute keeps sitting at it's original place and doesn't move when a rotate is applied. Is it because I use an attribute i.s.o plain text... Strange it works in "test" Any idea? Thnx in advance! Quote Link to comment Share on other sites More sharing options...
dbroada Posted July 4, 2011 Share Posted July 4, 2011 have you "locked" the attribute. If not, do so. They have to be locked if you need to move them. Quote Link to comment Share on other sites More sharing options...
BelCAD Posted July 4, 2011 Share Posted July 4, 2011 Yep is "locked" Quote Link to comment Share on other sites More sharing options...
dbroada Posted July 4, 2011 Share Posted July 4, 2011 and chain action is set on one of the actions? edit......... to put it another way, you certainly can use move with attributes Quote Link to comment Share on other sites More sharing options...
