placing ifeature automatically in a different face from its creation

[Anonymous]

Hi everybody

I´m trying automatize the placements of T slots via ifeature. I need be able to put slots in faces paralells to XZ or YZ planes, whith its simmetry line parallels to Z axis and minor width to the top.

In addiction to measures, I want define locating also automatically,
without manually translate/rotate its profile after complete the Ifeature insertion.

To achieve this, I select a top line and a left line to locate the T-slot.

Initially I used a face paralell to XZ plane to generate the Extrude/Subtract
feature, and so I extracted the feature, as know.

But when I try apply the Ifeature in the ortogonal face, Inventor alway rotate the sketch,
seems using the center of selected face ora other point.

I know that Inventor always make a rotation of the sketch origin in this situation, but
is there a way to avoid this and put the slot in the right way, automatically, using ifeatures?

Many thanks in advance!
