Lost Dynamic Block Functionality

[ksperopoulos]

I have created a lot of dynamic blocks that have multiple parameters/actions (i.e. polar stretch, visibility, linear stretch, flip, etc.). I can insert the block into the drawing and manipulate the block using these parameters/actions. I copy the block to as many places in the drawings as needed and adjust as needed. But after I save the drawing and open it up the next day, the blocks lose all their functionality. Why do I lose the functionality of these dynamic blocks and is there a way to get those parameters/actions back?

This will seem like an oddball approach, but try creating the blocks again on a different computer to see if they work. I made a bunch of blocks at work that would constantly lose their dynamic-ness, but I re-created them at home (using the exact same procedure) and emailed them to my work account, and they work perfectly (even if I C&P or save the drawing and reopen it).

[ksperopoulos]

Would I really have to recreate them? I put in a lot of time to these blocks that may take a lot more time to recreate. Do you think that if I opened the original block file and did a SAVE AS it would do the same thing?

[SuperCAD]

Nope. I tried everything I could to re-save/re-name the blocks to see if it would help, and it would only work if I recreated the block on my home computer. I don't know if anyone has come up with a reason why some blocks act this way.

 

All I'm saying is to give it a try. If it works, then you know what you have to do. If not, I can't help you then.

These blocks are a part of our departments template. Are you saying I need to recreate them on everyone's computer?

[SuperCAD]

No, just try it on one other computer. Then try them on other computers to make sure they work for every one. Otherwise, try making a less complicated block. Simplify them as much as you can.

Seems rather strange for that to happen- I've never had a problem with dynamic blocks- any chance you could post an example?

Could you be saving the drawing and blocks as a previous version of CAD which did not have Dynamic block functionality? I don't know exactly how AutoCAD handles unsupported data when you save the drawing to a previous version - I think that I read it keeps the info but won't let you use the dynamic part.

 

Check Tools - Options - Open and Save.

I have had similar problems. I created a drawing and added dynamic height blocks, after opening the drawing few days later the inserted block names had changed and they didn't have the blue drop-down triangle where I can choose which attributes to display. However i could insert the original block and it worked fine, only the previously inserted ones had turned into vegetables

It is exactly how Krztoff describes. See attachment.

Hmm, today I had the same issue and was simply using the BURST command on my blocks that had changed, and i noticed that i had to use it twice on each block to have them blown to bits, and then i noticed that if i use it once, the dynamic block functionallity returned, i don't know if this will help in other cases but worth giving a shot.
