Exercise: CURVE FROM EQUATION

Create a 'Datum Curve' with the #From Equation option.

Below is an example equation that will generate a helical/spiral shaped curve based on a Cartesian coordinate system:

Where r is the cylindrical radius; theta is rotational angle; t varies from 0 to 1; z is the 'out of plane' height of the sweep

You must use an Advanced Swept Blend for the solid sweep.

• Feature > Create > Solid > Protrusion > Advanced > *Solid > Swept Blend > Done
  * Use Thin if the sweep is hollow
• Choose Done (Sketch Sec/NrmToOriginTraj)
• Choose Select Traj
• Choose One by One, and select the curve. > Done
• Pick Xvector > Done (Automatic doesn't work here)
• Csys > Select the coordinate system you used for the equation
• Select the Z-axis > OK
• Accept the z-axis rotation of 0.00
  

Sketch the sweep's profile (Circle):

• Select the Z-axis > OK
• Accept the z-axis rotation of 0.00
• Sketch the sweep's profile:
