Well that's my problem, how do you sketch a 3d trajectory? That is, a sketch along the X, Y and Z planes?


New member
there are a number a ways to sketch a 3-d trajectory.

you need to create a datum curve. you could do this by the 2 projection method, or project a curve onto a surface, or from equation.

i prefer using the equation method. you can input the trajectory using either the cartesian or the polar system. if not, so what hazmatt suggests using the 2 projection method. it will combine the two separate curves you make.

in response to nkpham:

a 3d curve created thru points will not work as the trajectory of a regular sweep. it is an invalid trajectory. a variable section sweep must be used to utilize a curve thru points.
