INVISIBLE DIMENSIONS SHOWN IN VAR TABLE


I’m playing around using Variable Tables. I have a file that I’ve already created
several elements/dimensions etc. I opened the VT just to see what it looks like.
I noticed that there much, much more dimensions listed than I could see in the
Model. So I started selecting them one at a time in the VT to see where they were
located in the Model. I found several in the Model that could be seen as they were
selected in the VT but I couldn’t see when not selected in the VT. It’s as if they
were invisible until selected in the VT. I double checked that I had all layers
visible and that was not the problem. So I started deleting the ones for which
I could not find a function. That’s when I decided to submit this for clarification.
What is going on?
Thanks,
Ron

Ron,
Send the file to me and I will check it out.

Ricky, here it is. I did a little experimentation. I did a Ctrl A to select all
while the VT is open. Only the visible dimensions will highlight in the VT. Also,
I dittoed and copied over to a "clean" file and did another Ctrl A. The number
of unhighted dimensions in the VT in the clean file was considerably less but there
still were many that didn't highlight.

Ron,
What you are seeing are dimensions that are within blocks that are part of
the file.
There does not have to be a visible occurrence of the block for the
dimension to display in variable table.
Variable table is for the overall file, not just for what is visible.

Ricky, I guess that makes sense. But I experimented with a empty file and created
a dimensioned block while the VT was opened. The dimensions showed up in the VT
during creation but disappeared as soon as I ACCEPTED it. So yesterday I thought
that block dimensions aren't supposed to show in the VT. However, I just did the
same thing but this time, after creating the block and saw the dimensions diappear,
I closed the VT and reopened it. And than the block dimensions were in the VT.
That makes you correct, of course.
But here's another quirk. In the same file, I copied the block to make two identical
blocks. I did this twice, once with the VT opened, than closed and reopened and
again with the VT closed during the copying. Each time when I opened the VT only
one set of dimensions showed up in the VT. The dimensions of the copy were not in
the VT.
Why is that?

Re: INVISIBLE DIMENSIONS SHOWN IN VAR TABLE

Ron,
Good question!
The reason you only see one dimension in the variable table is that there is
really only one dimension.
When you place multiple occurrences of a block, you are placing multiple
visible references to a single set of geometry.
If you open one of the occurrences and modify the block, all occurrences
will change.
So if you add or remove a dimension to or from a block occurence, it only
applies to the master block objects.
But all occurrences of that block change.
This is the same with lines, circles, arcs, etc.
