Title: Linking attributes to parameters with calculations?
Post by: CHulse on January 09, 2009, 02:59:31 PM: 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

Post by: CHulse on January 09, 2009, 03:15:42 PM: 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...

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?

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 (http://www.primeservicesgloabl.com) on the free tutorials page found there.

I'll check it out, thanks Michael
