Change origin point of shape and translate it

[IonutAlixandroae4]

Hi all,

I have a question regarding shape manipulation in CGA. I have used a rule that generates a footprint inside a parcel based on a coverage value (e.g.: a footprint inside an original parcel that occupies 50% of it).

Below is a print screen of it.

As you can see, the yellow shape is the footprint generated that occupies a certain percent of the initial geometry (the white parcel). The thing is that the footprint is placed at a certain origin (here is 1);

I would like to know how can I move the footprint at other origins like 0, 2, or 3, and also to be able to translate the footprint a certain value from the specified sides? 

I would like to have like a drop down list in which to choose one of the four origins that would move the footprint`s origin and four attributes that would move the footprins from the specified side

I have tried with functions like setback but I cannot make the function recognize the four sides.

Also, to change the origin I`ve tried the function about scope and pivots but I do not think I have understood very well..

Thank you !

You can move the footprint by translating the geometry first using t() and then resizing the geometry afterwards.  When translating, you can use the apostrophe (ex: '1, '0.5) to move it a relative amount, or you can use scope.sx, scope.sy, scope.sz.

To make a drop down list from which the user can select a value, you can create an attribute and use the @Range annotation.
