AutoCAD Dynamic Block Constraint Setup

I need an experienced AutoCAD user to open my existing dynamic block, step into the Block Editor and apply a reliable mix of distance, angle and coincident constraints so the geometry stays true no matter how the block is stretched, rotated or mirrored.

there will be a total of 9 blocks The block is built from a handful of lines and a couple of circles; those are the only elements that need to be parametrically tied together. I’ll supply the current DWG. Your deliverable is the same file returned with the constraints fully applied, plus a short note (inside the file or a text snippet) explaining the key parameters so I can fine-tune them later if required.

I’ll sign off once every grip action maintains the intended proportions and relationships without manual adjustment.
