Draft direction and Neutral Plane

andreas_scholzandreas_scholz Member Posts: 14
I wanted to create a part which is 22° orientated to the draft direction. When I select  a neutral plane the draft will be done normal to that plane? What about the case I want to select a neutral surface that is not planar?

    When you select a face or plane to sketch on, it will always be normal to that face.

    You can only create a sketch on a flat face.

    If it is non-planar you will need to construct a plane first before creating your sketch.

    Hello to all,

    to make it a little bit more clear, please have a look at following simple example:

    https://cad.onshape.com/documents/b962676889c09f0d0bc6289d/w/51621f26a0d37db7347e9962/e/254f7c88e261e2fecd5ed4a1

    It is only one feature of a small plastic part I wanted to create last week. As You see the part is extruded between to parallel planes with an angle of 22° degrees to the top plane. The part should have a draft of 0.5° normal to the top plane (see direction arrow) as main draft direction (there are additional features that call for this direction!) with the upper plane as neutral plane. I am not able to draft the part in Onshape in that manner.

    What if the upper surface would not be planar and also should be the neutral surface for draft?

    I am primarily working for automotive industry where draft directions are often set, and adjacent surfaces or parting (neutral) elements for drafts are non planar.

    Thanks in advance for answering.

    Regards

    Andreas

    Hello again,

    I wrote my question in the category "IMPROVEMENT REQUESTS" because I am shure, that it is actually not possible to draft parts in Onshape as mentioned above.

    So my article would better be moved to the correct category.

    Regards

    Andreas
