Curve by formula

 

 

 

Links / Videos:

 

This command allows you to create a 3D curve by providing its Cartesian equations.

 

Creation Stages / Use:

 

Choose the command 3D Sketch > Operation > Curve by formula... from the drop down menu.

 

  1. Enter the formulas along the X, Y and Z axes of your curve.

  2. Enter the minimum and maximum intervals of parameter t.

 

 

 

 

 

This command does not manage the curves that are not continuous in tangency. So it is necessary to check that the provided formulas properly generate a G1 type curve within the given interval.
