Sweep Start Growth geometry problem

Recommended Posts

How can I fix the start growth geometry

I played with various settings but didn't get where I wanted

    I recreated your issue and it might be that there is an incorrect setting in the rotation curve of the sweep. Just a guess though since there was no file supplied.

    The cube.spline because of all of the twisting, when it joins back on itself is rotated. A quick fix is not to have the cube.spline closed. So uncheck the closed option. You then need to grab one of the end points and snap it on to the other end. This makes it look like the spline is closed. This should remove the unwanted twisting. You might need to tweak the position of these 2 points so that they aren't near a corner. This will then make the pipe geometry join together more smoothly.

     

    Hope this helps.

    yeah, I was thinking to cut the start point

    I can't uncheck closed because I made edges to spline conversion from polygon edges 

    so I figure somehow cut the end point (?) is that even possible ?
