Hello In proe you select a surface then the hole tool. The hole is then placed where you clicked on the surface with drag handles to select the reference planes for dimensioning. Is this possible with UDF's? I have sketched holes we use all the time, within my UDF you have to select the placement plane & two reference planes then the sketched hole is placed. It would be nice to call in the UDF and drag the the handles to the planes I require also drag the feature where I wanted it. Thanks Geoff
