working/mating 2 perpendicular sketches? 1

[skanskan]

Hello

How can I use the intersection of two lines on another sketch in a perpendicular plane?

Or something related...

I've posted a very simple file, with two perpendicular non-concentric circles.
How can I get the circles to cross (pierce) each other?

If a try to resize one of the circles by dragging it with the mouse I'm not allowed to choose a point on the other plane as my target.

I've also tried by using mates and by converting entities, with no luck.

I know I could use 3DSketch but it does have many limitations (Such as revolving curves).

I'd like it to see Solidworks fully working on 3D and not on projections on planes.

Add a horizontal construction line from the centre of the Sketch3 circle, then use the end point to Pierce the Sketch1 circle.

All sketch elements can be created in a 3D sketch. Planes are not necessary but do help to simplify.

I've tried adding construction lines but if they are on a different sketch (at a different plane) I can not select them from the other one.
I don't want to use 3Dskecth because with it one can only use some SolidWorks functionality

Do you think any other of the bigs (ProE, Inventor, Catia, NX...) is better/easier to do this kind of things?

Yes you can! See attached.

Could you explain the shortest way to do it, please?

See my first post.

OK, thanks
It works,
I guess is not so easy if the planes are not perpendiculars or coincident with the main planes.

I was trying to use the "coincident" mate with both circles, I don't know why it doesn't work. The "pierce" option must be used instead, as you said.

I've seen that one of my problems is that sometimes I open a sketch and then all sketches created later get unavailable and then I can't select anything at them.

And it seems that one can not resize any of the circles in 3D, you need to edit one of the sketches.

SW is history based, so yes, if you edit a feature created at one point in time, anything created after it will not be available.

To be able to resize any sketch features (2D or 3D) without entering edit mode, the sketch elements need to be dimensioned. Double clicking the sketch (or feature) in the Feature Manager will then expose the dimensions for selection.
