Options

The following options are available:

:BLANK_PART - specifies the name of the part to be generated.
:WP - specifies the workplane containing the profile to be swept.
:AXIS - specifies the axis about which the profile is to be swept.
:PITCH - specifies the distance by which the profile will move in the axial direction per turn.
:TURNS - specifies the number of turns for the helix. Any decimal number can be used.
:RIGHT - specifies the sweep orientation. By default, the sweep path for the helix has a right-hand orientation (just like a standard screw thread). Switch this option off if you want to change to left-hand orientation.
:PREVIEW - enables you to preview the helical part.
:CHECK - Automatically checks part integrity during the helix operation.

When to use

Use this action to create a helical part.

Example

The following example creates a part named hsp12 by performing a five-turn left-hand sweep about an axis defined by two points. The pitch of the new helical part is 40. The Preview option is used.

HELIX_ADD :BLANK_PART "/hsp12" :AXIS :TWO_PTA (gpntwc 21 27 3 "vport1") (gpntwc 21 63 3 "vport1") :PITCH 40 :TURNS 5 :RIGHT :OFF :PREVIEW
