dynamic block or parametric design?

[manulele17]

Hello, I am emanuele and I write for the first time only now, as I always found the answers I was looking for in this super-forum!
My problem is as follows:
design a rectangle (@40,2000), I create a dynamic block with linear stretching action in order to change the short side. no problem.
positioned the rectangle with ref point the edge at the bottom to the left, I would (but I don't know how) be able to take as grip the opposite edge (top to right) and be able to stretch and rotate the rectangle. keeping it a rectangle and not a parallelepiped. my block should therefore have two edges on the diagonal and be able to rotate and stretch, always maintaining rectangle lipmetry and a side with determined length with the parameter.
If anyone has any ideas... I thank him so far.

hi, when you define the block you have the option to specify the base point select point....
now open the block then enter the point parameter in the opposite summit to the one chosen in the previously described phase. close the block by saving it.
when entering the block this is taken by default from the point defined at its definition but, if you press ctrl your figure moves with the point parameter on the cursor. In the same way you can insert multiple insert points (small word game) which in turn will be coincident with the cursor to the pressure in sequence of ctrl. easier to make than to explain.
with regard to rotation, possible even without the rotation parameter, the thing is a little more articulated.
through the rotating voice present in the property panel, which should always be left open, you can act on the rotation of the block limited to the single point of insertion chosen during the definition of the block, to set the rotation according to the other point of insertion you will have to set a rotation parameter according to that specific point. This parameter will appear at the bottom of the property panel, in the custom field at the angle 1. rotation can be placed numerically, the most convenient and precise option.
Now two separate rotations can be imposed on the block, each binding its summit.

Hi.

Thank you very much, solved with geometric and dimensional constraints.
I would have another question on the subject:
is it possible to associate to the value of a parameter the color of the block? I sypego better, paramentro = 20 the block colored red, paramentro = 40 the block colored of green. Do you have ideas?
