Re: [Plugin] Cyma Curve ToolI just tried it with the same settings, V8 on XP and had no problems with it.

Re: [Plugin] Cyma Curve Tool
I tried to use this to make pipe transitions: bend the pipe xinches and continue in the original direction. A ratio of 1.414 does not result in vertical for me (both ends do not extend parallel) Also, a "followme" circle most often results in a long tapering cone off of the opposite end! i74930K 3.4Ghz, 2x GTX780 6GB, 32GB DDR31600 ECC, OCZ Vertex 4 500GB, WD Black 3TB, 32TB NAS, 4x 27" Monitors, SpaceMouse Pro, Xkeys XK60
Re: [Plugin] Cyma Curve Tool
Bob A Cyma Curve is really for making moldings and profiles, and not for 'followme' pipe bends... A ratio of 1.414 won't give exactly parallel start/ends as it's not exactly sqrt(2)  To enter the more 'exact' value type sqrt(2)  it's easier that typing 1.414213562373095050 etc... However even that will give slightly 'off vertical' ends, as the tolerances in the Maths etc... For some reason the Cyma Curve will not always make a good 'followme' path with PipeAlongPath  but with 'vanilla' FollowMe it's better... If you add short horizontal bits on the ends of the Cyma Curve and use the three as the path it should then give vertical terminations, like this... You can then move the end circles horizontally to change the 'leg' length as desired... TIG
Re: [Plugin] Cyma Curve ToolThanks, TIG.
I realize using this tool for pipes (actually it's more often for electrical conduits) is a little "out of the box", but it was the first thing that popped into my mind when I saw it. Besides, even with adding short segments it's faster than drawing arcs or using bezier curves. Neat tool P.S. I was using the vanilla followme tool (but, yes, in the "real world" I would use PipeAlong Path). Sometimes, however, SU does not recognize it as a legitimate path. i74930K 3.4Ghz, 2x GTX780 6GB, 32GB DDR31600 ECC, OCZ Vertex 4 500GB, WD Black 3TB, 32TB NAS, 4x 27" Monitors, SpaceMouse Pro, Xkeys XK60
Re: [Plugin] Cyma Curve ToolCan you please explain the formula 2*Y/sqrt(X*X+Y*Y), particulrly the /sqrt part, i'm not familiar with the american way of math writing. Thank you!
Also, I thought the two parts of the curve were supposed to be different, based on Chord proportion [to make them undulate in such beautiful manner ]? Even if X and Y are different, the radius is the same, but I might got this all wrong Re: [Plugin] Cyma Curve Tool2*Y/sqrt(X*X+Y*Y)
The X and Y are the curve's enclosing rectangle's sizes. The '*' is 'multiply by' [×]  so that in this case it is 2 times the Y value [2*Y]. The '/' is 'divide by' [÷]. The 'sqrt' is the standard abbreviation for 'squareroot'. You can also use 'sqrt(nn)' in the ;input;, substituting 'nn' with the required numerical value  it will then find the squareroot for you: you can only add a number, not a formula... The '()' are used to show that you do the calculations inside them before taking the squareroot. Also the '*' parts within them are done before the '+'. Note that the part to the right of the '/' is basic 'Pythagoras' stuff... The default tool makes 'perfect' aesthetic curves according to the ancient rules explained in the helptext, but quite often these proportions are adjusted for other reasons, hence the opportunity to customize the values...

Re: [Plugin] Cyma Curve ToolI still get the weird glitch at the bottom of the cymas with all different settings, new windows 7 build, new sketchup installs, and downloading the newest version here... maybe its a plugin conflict???
after exploding, deleting the extra piece and then welding again, the dimensions are still what was input in the dialogue
