Parametric Blocks - is it possible to pass a parameter value in to a block attribute?

edited February 21 in 2D Drafting

I have a set of parametric blocks representing pipes.
each one have a parameter for the length.
is it possible to pass the block parameter (representing the pipe length) value to a block attribute?
I've attached an example block:
and in that block, I want the value of parameter d1 to automatically assigned to the value field of the QUANTITY attribute

PVC PIPE DN25 PN16 ID-21.2 GRAY_DY1.dwg


  • I did something that was update a attribute in a block based on another blocks attribute, you have to set the field to the attribute ID textvalue.

    Trying with simpler text from limited testing . %<\AcObjProp Object(%<_ObjId 103460128>%).TextString \f "%lu2%pr3">% can not put a field as value but I am happy to be shown if possible.

    thanks for the reply.
    I know how to get a value in to one attribute from another - this is not the case here.
    the problem is how to get a value from a parameter to an attribute.

    Read the question backwards you want d1 value for dynamic block is easy. An alternative may be use a field that is length of line so avoid parametric, that worked for mtext will make something for block att if can find time.

  • The answer is now in the lisp section don't double post its confusing.

    thanks for the reply!
    1. the issue is parametric block. bricscad don't have dynamic blocks, this is part of the problem.
    2. I accept your comment about the double post. lets continue in the lisp section of the forum.

    Bricscad support team sent me a short video that show's how to use formula field to assign parameter value to an attribute.
    I believe it can be helpful to others so I uploaded it over here.
    Many Thanks to Bricscad Team!

Origami is the Japanese word for paper folding. ORI means to fold and KAMI means paper and involves the creation of paper forms usually entirely by folding.
