How to reorient an In-Context Sketch?

Henk_de_Vlaam · January 2017

I like to make a steering connection rod (C) between the bush of the front fork (A) and the rack (B)

Fortunately it is possible now to use the new In-Context functionality.

I made a Mate connector in a hole in the rack as base for the context part studio and rotated it by guess so that I hope that the sketching plane of the new part studio passes through the center of the hole in A.
While sketching the rod (C) I found that the sketching plane did not pass through the center line of the bush hole (see square marking).
So I rotated the mate connector to correct the sketching plane. However the sketching plane did not follow that rotation. Note the angle between the sketch and the X-axis of the mate connector (see round marking).

Questions:

Is it possible to reorient/rotate the sketching plane after creation
Or even better: is it possible to create an In-Context sketching plane in relation to more than one entity (at this moment in context only one mate connector)?

If you have another entity that should lie in the sketch plane, you could define 3 Part Studio mate connectors in-context, one for each of the holes you want to connect and one for some reference entity. You could then use the 'Plane' feature with the 'Three point' option, selecting the three mate connectors as points. That Plane will be guaranteed to pass through the centers of the two holes as long as you can place the mate connectors correctly, and will update if you update the context.

Please see this video. Ignore the extrude operation I started to do. Does this plane help?

Would you be able to show the sketch plane you are using? You may have to create a plane first by connecting the center points of A and B and then create the rod sketch. Yet, I am wondering if the sweep path can be controlled much without 3d sketching capability.

@RK

I can only show the sketch plane in the In-Context part studio.
How do I create a plane or a connection entitity between the holes in the assembly? In a way, that is part of my second question.
The shape of the rod does not need a 3D sketch, only a 2D sketch plane in the right position is needed.

Now it’s clear.

ICD; what an impressive feature!

I succeeded to make the rod, especially with the help of Cody Armstrong’s https://onshape.wistia.com/medias/suv670wfof?utm_source=hs_email&utm_medium=email&utm_content=41042688&_hsenc=p2ANqtz-8goBt4_tdXslPA0vWS2kUFYx9DmdfghrZHMdahQ1ISoptZkeSR0hTYr2CJjVpi7SPCFhFIdLdAM9Hn-iD6m1yPIMKDfA&_hsmi=41042688 (very informative!), where at 50:45 it became clear that one can use other sketch planes then the initial ones that are created while selecting the origin or a mate connector.

@Jake_Rosenfeld and @RK : The hint of you both about the (sketch) plane through 3 points and how to make that helped me also very much. Thank you.
