Can't sketch on solid surfaces

[matt.hansen]

I have a student working in inventor 2017. He has extruded a sketch into a solid surface model. Normally, my other students would start the next extrusion by clicking on the face of the object and creating another extrusion off of the surface of the object. However when my student clicks start 2d sketch, and selects the face of the object he wants to draw on, the view jumps to the center of the x-y drawing space instead of allowing him to draw directly on the face of the model?

Thoughts on fixing this? TIA

Do you mean it is set to look at sketching plane while sketching?  Or something else..

Hi!

A sketch plane is only a direction.

Every face has his own axis system, and this is chosen automatically by the software, so, there's no problem there, just sketch using solid references to position the geometry int he sketch, doesn't matter where is the axis system.

If it is not the case, just attach here the part and we'll check that.

Just to clarify so that we are using the correct terms in the classroom.

A model is either a solid body or a surface body (or a combination of these).

A solid is not a surface (in CAD terms).

The face of a solid body is referred to as, well, a face - not a surface.
