Creating a line or sketch in 3D space (for a pipe sweep or channel sweep)

Maybe someone can understand what I am trying to achieve from these snapshots.

By the way it was very difficult for me to layout the circle sketch to the line shown above (its future path for its sweep).  I had to draw the circle sketch on a different plane and guestimate or eyeball a "move function" to align to the line in one plane and then do another guestimated or eyeballed "move function" to align in a different plane to ultimately achieve this layout.  Apparently the handy "align" function only works between components but not between sketches and lines even if a add a point to the endpoint of the line.

Is there a way two efficiently draw these types of structures?  I can't seem to find a practical way to have coincident lines drawn that jog at sharp 90 degree angles that create a pattern that is part of a 3D space rather than staying within a 2D plane.  Wish there were a way to attach the "triad" at the end point of the line and change the plane into which the line will extend like shown above.  This would allow someone to draw a line in 3D space rather than drawing segments and expend much efforts in trying to align components after creating them.

 

Maybe my challenge is that I am trying to use lines and construction lines and sweep paths to guide me in order to create a component, rather than making individual components and the stitching them together afterwards.  Sorry for my ignorance :-(.  HELP!!!!!  :-)

Hi! Thanks for posting.

 

What you want is entirely possible. Construction geometry will get it done.

 

Steps:

  1. Create your first sketch
  2. Use Construct > Plane Along Path
  3. Select the first sketch path
  4. Drag the arrow to the end where you want another sketch to start
  5. Okay the plane creation
  6. Start a new sketch on this plane
  7. Use Sketch > Project Geometry to project the end point from first sketch path onto this new sketch
  8. Connect the second path to this point

This process can also be used to connect the sweep profile to these paths.

 

When you use Sweep you must select the paths in sequence.

 

Cheers!
