How can I create a new sketch over extrudes?

Hi, I'm a newbie to onshape.

I'm learning how to use this marvelous tool!

Anyway, I'd like to create a sketch including surfaces [1], [2], [3] at once. (They all have same heights)

Unfortunately, when I select the surface [1], and create a sketch, I can't select the points on other surfaces (2), (3), (4).

For example, if I start drawing a rectangle from the point (1), I can't finish it on the point (3) because the surface [3] is not included in the current surfa

When creating the rectangle it will not snap to and automatically become coincident to those points but after creating the rectangle you can manually make those points coincident.

@sangseok_yoon, Currently in Onshape you can snap only to that entities of the face which you choose as a sketching plane. You can select other surface entity also by projecting entity with the help of use command. Please refer below video for more detail.

I hope this will be helpful to you.

And one of great functions in Onshape is that you can reuse sketches and for example create similar rectangle plate as you have in bottom just using extrude and adding 'Second end position'
