I'm trying to get a helix with 1 revolution to start off straight and end straight so it will be tangent with a piece of tubing. Does anyone know of a way to accomplish this easily?
This is a pretty hacked way of doing something. If I was using NX, I would "just" to and make a blend curve from the helix to the straight line. I can't seem to find an easy way of doing that here. I tried to manually do it with surfaces to get a blended line. I was also thinking of trying to make a surface blend from the helix to the straight boss and see how that goes. That might be easier. So far, I don't feel like SW is good at these particular design challenges. I have added the part to try and see what I did. It's a mess especially since SW doesn't like to reuse geometry for other features.
This should get you on the right path, look at the part that I uploaded and instead of a radius at the end make it a straight line
How to create a helical cut with a radiused taper?
Thanks for the quick reply, unfortunately I'm unable to open your part. Based on what you wrote in the other thread I have converted the helix in a 3-D sketch, the issue is on a drawing level I need to have the true image of the helix and straight pipe shown in one view. If i make the pipe tangent to the helix there is a skewed view of the pipe and if I make the view relative to the pipe the view of the helix is skewed.
Click on the Helix Circle Sketch and select View/Normal To - then hit your space bar/new view or re-set standard views and try the new views in your drawing
That's not exactly the answer that I'm looking for. I'm not really sure how to explain it other than I need the ends of the helix to come off straight, say relative to the z-axis, and not at some wonky angle like it does.
Did you model the part like you need it or do you need to the model corrected as well??
Can you up load the part??
Here's a couple of alternatives using solids rather than surfaces.
The surface model does take less time (.02s to .03s) to rebuild but it has many more features.
In 2016, you can make these sweeps using a pre-defined Circular Profile so you would only need to sketch the Path. Makes these types of sweeps (circular profile) even faster to make.
Good luck with your project.
This has always been a thorn in my side! No simple way to do it.
