Using the arbitrary section option to calc Mom of Inertia

[JohnM]

Hi all,
I have created a Z beam as shown in the attachment with ease, and it represents the rim inner edge lip of a racing car wheel.
Changing the angle of the lip extension, shown in yellow, will increase Ixx and to do this I need to use the arbitrary section tool.
Q1
I cant get the radii to go in the opposite direction to the previous one like the Z section. It keeps going in the same direction to make a box.

Can anyone do a few lines of coordinates in the table to produce the opposite radii please.

Cheers
John

ce an Z or S shape ?

Hi John,

Thanks for reaching out, and apologies for my late response. you can rotate your section in the negative direction to achieve the yellow line, as I have shown in the screen shot below.

Please let me know if this addresses your issue or if you have any further concerns.
