-- This issue might be due to a bug in SolidWorks 2014 SP2 --

I'm trying to route a water hose from one location to another without passing through a keepout area (the red box shown).

I am simply sweeping a circle (red sketch) along a Projected Curve defined by two orthogonal sketches, one on TOP (green curve) and one on FRONT (blue curve).

enter image description here

It's very nearly working, apart from that I cannot seem to persuade Solidworks to complete the Projected Curve. It always seems to stop short of the final location.

Each of the two control curves begin and end with straight line segments that are tangent to the spline that governs the path. I need these to get a nice, straight controlled entry/exit from the flat surfaces.

The control points begin and end at the same locations in space (projected onto their respective planes).

What am I doing wrong, that is preventing this curve from being completed?

  • $\begingroup$ Why not do this with a 3D Sketch/Spline? You'll need to provide more screenshots, or a copy of your files if you want diagnosis of what's causing the projected curve to not work in this specific instance, since it worked for me when I just tested it! $\endgroup$ – Jonathan R Swift Feb 13 '18 at 9:28
  • $\begingroup$ Because I want to know what's wrong with the way I'm using the "projected curves" feature. I'm either missing some crucial step or it's a bug in SaladForks. $\endgroup$ – user6335 Feb 13 '18 at 15:54
  • $\begingroup$ It's not a bug with SolidWorks - as I said, it works for me... Proof. Perhaps there's some discontinuity in your sketches or something? You could try creating a new sketch, and using the 'Fit Spline' Tool to create a continuous single curve that is in contiguous with the sketch you were trying to use. Then use those new sketches as the basis of your 'sketch on sketch' Projected Curve. Unfortunately without more information I can't answer your question ("What am I doing wrong...?"). $\endgroup$ – Jonathan R Swift Feb 13 '18 at 17:13

    $\begingroup$ I'm starting to think it is a corner case bug in SW2014. I'm having a hard time reproducing it with different geometry. Flagging to close. $\endgroup$ – user6335 Feb 14 '18 at 9:59

    $\begingroup$ Your self-critical attitude is very positive, but I think this question doesn't deserve closure, what if others have later the same problem? $\endgroup$ – peterh - Reinstate Monica Feb 14 '18 at 10:42

I'd recommend using a 3D Sketch Spline for creating your hose - this will more accurately model the natural shape that the hose would assume given the boundary conditions of perpendicular to the grey transparent block at the in/out positions. Let me know if you have any questions regarding this method:

  • $\begingroup$ +1, accepted. If it does turn out to be a bug in SW2014 then your answer solves the problem. May I ask what screen capture software you use? It does a good job of shrinking a SW session. Thanks for the help. $\endgroup$ – user6335 Feb 14 '18 at 10:03
  • $\begingroup$ I used LICEcap - I'm glad I was able to be of assistance! $\endgroup$ – Jonathan R Swift Feb 14 '18 at 10:20
