50% yes, I want something like fields when working with text, I am searching link properties valies with anything, I mean for example, if field can extract the line length, at the same way I want to edit the text and that the line length change, no sure if possible, this is similar to when constraints edit any length editing dimension.
... another example, is, I want to link the poyline elevation of polyline to 3D cube size in the properties panel, I mean If I edit the elevation then the 3D cube size be edited automatically.
