Hi @Abeinjapan Thank you for your video!
I just want to know what tangent magnitude =1 means for the pole placement. In other words, I want to know how to make the sketch spline conincident with the bridge spline, only by dimensioning the poles, but not by snapping and constraint.
Not really sure how to answer your question other than say that the sketch spline definition and the bridge curve definition are not the same. Instead of using through poles to define the sketch spline, you should use through points. In that case the definitions will be very similar.
There are many options which alow you to define the exact shape of the spline within either function so it is a bit like comparing apples and oranges.
Hi @Abeinjapan Thank you for your reply!
I think I didnot clarify my question. I just want to know how Bridge Curve calculates the pole position when the tangent magnitude is specified to be 1, 1.5 or 2 ...
Because the command has so many options to help control the shape, the continuity (G1, G2, etc.) is only relevant to the start and end of the curve. The middle part is controled by the 'Shape Control' settings. You should look at the online help for more detailed info on each of the options.
In your example you are using 'Tangent Magnitude' which defines a percentage of tangency. I am not really sure how the percentage is calculated.
Hopefully someone else will chime in here and explain what the percentage value means.
