Circle is a 2D sketch on the front plane. Other sketch is 3D. What is the meaning of this arrow mark? Circle is on the front plane therefore it is understood. What is the meaning of 3D sketch showing front plane.
I'm guessing that one of the points on the 3d sketch is coincident with the front plane somewhere.
This is showing you a Parent relationship.
In this case it is showing you that the 3DSketch has some relationship to the Front Plane. You can turn off the display of Parent/Child relationships, but they are really helpful when you understand what they are telling you.
I believe that the Front Plane is basically the "default" for sketching (much like when you create an InPlace mate in an assembly.)
Just for grins, I did a quick 3DSketch that completely avoided the front plane, and got the same results . . .
Again, just a "wild guess" . . .
Some relationship with the Top plane as well.
I'm not sure why it's showing a relationship to the Front Plane. I get the same results even if there is no sketch geometry added. The 3D Sketch itself has the relation to the Front Plane. My Part template opens up with the Front Plane Normal to the screen so perhaps that is why it's the Front Plane. If I orientate my Top Plane normal to the screen & start a 3D sketch, it still has a relation to the Front Plane.
Fact is 3D sketch is not on any plane therefore it is a red herring information.
NO, you can have a 3D sketch completely lie on one plane. The Front plane, in this case (because i just tried it, acts as a default plane. I drew an egg without placing it on a plane.
I mean that 3D sketch can't be on any origin plane.
So, Maha, exactly what is the problem?
Not any particular problem. When I investigated a long tree this problem arose.

Insert a new part into an assembly, when you click on any face or plane to create the InPlace relationship, this will become the "Front Plane" of the newly created part. Like I said, I believe that the Front Plane is basically the de facto standard parent feature, and maybe the only reason is that it is the plane listed first in the feature manager tree.
I see this as a pretty interesting find. I know it really doesn't matter in the grand scheme of things, but understanding little things like this is the foundation behind understanding the big things and how Solidworks works. Apparently everything needs a parent (except the standard, default items that are already in a part).
