Topic: Linking attributes to parameters with calculations?

[CHulse]

Is it possible to pass numeric data from an attribute on to a parameter (linear) with a calculation (such as multiply it by 1.5)?
Is it possible to pass numeric data from an attribute on to another attribute with a calculation?
Is it possible to pass data from a parameter to an attribute?

and if any of this is possible, how please?

Thanks

Not





yet.

well that was easy...

depending on application, this may help.

Well, what I'd like to ultimatly do is insert a block and enter a unique ID# (tree number) as a single attribute. Then I'd like it to link to a database, look up other data about the tree and adjust a set of linear parameters accordingly.
Short of that, I was hoping it could take an attribute with a tree diameter and calculate a couple of other parameters from it.

Currently, I just enter the various parameters as calculated in an excel sheet manually into a VBA form that passes them to the block before I place it.

Pipe dreams perhaps...

There is ="currently"= in Autocad 2009, no way to make "Dimension A" equal to "Dimension B plus 8.44cm"

However, there is a "lookup" function to dynamic blocks that may get you by.

This can be done to some extent with Description Keys in C3D.
You could also do this with a Range Table in MAP.

Could you elaborate please?

oops, didn't notice the C3D tag in his signature... *bows out*

Cool, I wondered what those were. ...but I need to be able to enter any number from 1 to 100 or more including decimals.

With Description Keys one has use of up to 9 string characters to describe the point. Be default the first  is used to SCALE the point symbol (like a tree), the second to rotate the symbol.

The process with MAP and range tables is a little more complicated.  However one does this through a querry operation.
You can see the Description Keys set up on my site www.primeservicesgloabl.com on the free tutorials page found there.

I'll check it out, thanks Michael

How about creating your own xdata for your specific items?  That's essentially what the Description Keys are if I'm not mistaken.
