Blocks showing selectively when drawing is x-ref'd in....

Recommended Posts

CADsince07

Hi there, my colleague has effectively x-ref'd drawing A into drawing B and frozen all irrelevant layers.

 

There are a few blocks she wants to display. Some of them display as expected, some don't show at all. This is happening within the same viewport even. There are no attributes - block is a very simple solid filled rectangle (sometimes with an outer offset rectangle.

 

The layers are all the same.... the properties seem to all be the same...

 

Within a single viewport some show and some do not, despite appearing to have the same properties? Have looked into annotative scales, layer properties etc..... why would some appear and some not?

 

Hoping someone can give me some clues....

 

Many thanks

ALSO - it is not a viewport issue. The blocks show/don't show in the model space just the same

Blocks can do things that seem strange until you understand them. If a component of the block is not on layer 0, for instance, it will disappear if you freeze its layer, no matter what layer the block is on.

 

Another explanation is proxy objects. The objects that aren't displaying may have been created with some software that your version of AutoCAD doesn't recognize. They may even be from a later version of AutoCAD. It's not always obvious when an object has an unknown component.

 

Here are some things to check. Which objects are not displaying? Is it a specific set of blocks, that is, does block A always appear while block B never appears, or is there some other predictable factor? Where did those mystery objects come from? Did your colleague create them? Which version of AutoCAD created your "drawing A" and which "drawing B"? Does she have some third-party package? Has she purged or audited that drawing recently?

 

Not sure what the word "effectively" means here. "Successfully"?
