measuring spokes

[[Me...]]

hello i have to measure some spokes on a part. what feature do i use to measure this? Im am using duramax with xxt head. I use distance symetry and it works for the first one at 90 but since the rest are at an angle it does not work.

I would create a symmetry of each spoke then go to the drop down Form and Location and pick Angle between Features.

If your trying to ascertain the angle between spokes...
Measure the top of th part ands call it Top_Plane
Measure the OD of the part and call it Hub. To get points to connect to the hub,

Scan a plane on either side of each of those six spokes.
You have six spokes. so twelve planes.

1a, 1b
2a, 2b
3a, 3b
4a, 4b
5a, 5b
6a, 6b

Goto, "Construction"----->"Symmetry"
Double click on the Symmetry box in the Features List

Name it as follows:

Spoke_1, Select 1a for Feature1, 1b for "Feature2".
Spoke_2, Select 2a for Feature1, 2b for "Feature2".
Spoke_Etc....Repeat this for Spoke_3 thru Spoke_6

Now create 6 lines and recall the hub and a symmetry point for each to create the spoke lines.

Next go to "Form and Location"------>"Angle Between Features"
Double click on the "Angle Between Features" box in Characteristics List

Select Spoke_1 for "Feature1" and Spoke_2 for "Feature2".

Rinse and repeat for the other 2..
I would try to constrain everything perpendicular to your top plane. but I dont think its going to be an issue if you have ±.5° tol.

If you get irregular angularities, you can project or intersect each of those symmetry spoke lines to the top_plane and measure them from there.
