Jake here, first post on the forum, been using Sketchup on and off for ~5 years, but this is the first time I’ve needed real help.
So I’m working on a model that has a complex double-helical structure, and the first portions of each helix were relatively straight-forward: using circles as guides to draw the necessary lines. The last segment of the helix is driving me crazy though–as you can see, the form opens up in a gradual curve, so evenly spaced circles won’t work. To get that top line, I unfolded a semicircle into a straight line, placed the connecting segments at each end, put a tangential arc between them, and then curved that tangent around the circle [If that makes no sense, I can try to explain it with more pics.] Time consuming (even more than normal), to say the least.
What I’m wondering is this: is there any quicker way of doing this, or am I going to be stuck in modeling purgatory for a while? The final intention is a human-scale additive manufactured prop, so it has to be exact.
(Worthless bonus points to anyone who can guess what this is going to be )
