Parametric Block question: attribute won't stay in place

Hi all,

trying to create a parametric block for axes in my drawing. Simple layout, two circles with an attributed text in them connected by a dashdot-line.

Ideal scenario for now, create a parametric block (or dynamic block since we can in this version) that has a parameter length of the dashdot-line between the two circles with text and that is annotative where in a different annotation-scale only the size of the circles and text (and the scale of the dashdot line) changes, not the overall scale of the block.

A little picture to clarify my attempt:

  • left is the basic layout where 'AS' is the attributed text centered in the circle.
  • middle is the created block that shows the parameter and it's base point. Also visible here is that when changing the annotation scale, the whole block changes scale.
  • right shows that when extending the dashdot-line the text-attributes move in a strange way.

Who can help me with this? I've also tried it with a dynamic block, but in the current version I don't seem to be able to select the text-attribute as an object the dynamically move along with the stretch parameter.
