am doing a skeleton model of a pipe.
Can I usa a 3d sketch in a dereived
part?
The 3d sketch is not visible/selectable in the derived part. Any
suggestions ? (without IV Pro)
I want to use the 3d sketch to model all
the individual parts, bends and pipes.

Works fine here.
I always use 2D sketches to create and control my 3D sketches.

Can you currently do that ???
Yes. But not exactly as you describe. I think you might be doing too much work.
I do not believe the above can be done. I've tried everything possible but CAN NOT DO IT. Does anybody know of a way????

It would be good if you could create a 3D point in space that can be driven (moved around) by 2D sketches. .. First create a Front View 2D sketch and a Plan View 2D sketch. Then place 3D points in space that are driven by those 2D sketches. Then draw 3D lines between the 3D points. .. Then when you adjust the 2D sketches the 3D points would move and the 3D Lines would adjust. Can you currently do that ???
If you have a curve on a "front-view" 2d sketch and a point on a "plan-view" 2d sketch, you can create a 3d point that is driven by these 2d sketch entities (by intersecting the surface extrusion of the curve and a work axis through the point, as you probably know).
But, I guess, you want to independently control 2d sketch points in the 2 sketches. AFAIK, in a general sense this is not posible, because 2d sketches are ordered. Let's say that the top-view corresponds to the XY plane and the front-view coresponds to the XZ plane, and that the top-view sketch is above the front-view sketch in the browser. In this case the x- and y- coordinates of the 3d point would be controlled by the top view and the z- coordinate would be controlled by the front-view. The important thing to recognize is that one-cannot independently control the x- coordinate in the front-view. This is a simple illustration of the connection (or coupling) between the two sketches that make it impossible to control them independently since we cannot have an unordered (or variational) relationship between the sketches.
But in practice, in most situations, there are ways to achieve the degree of control you want. If you could describe your problem in greater detail, perhaps someone can help.
If you want to use points as the driving entities, you could use grounded 3d work points. Then in "front-view" you could use "Move/Rotate" tool to move the point in the XZ plane, and in "top-view" move the point in the XY plane.
The Workpoint command button has a "pulldown". One of the choices is "Intersection of Plane/Surface and Line".
Glad to help...
Another possibility (possibly easier) is to use the "Project to Surface" command in 3d sketch.
- pick the surface for "Faces"
- pick the sketch point for "Curves" (including multiple sketch points on the same 2d sketch)
- use the default "project along vector" and the default vector direction
This should create an associative 3d sketch point.
