GWR 5'2" WHEEL IN 3D
Read 331 times
* May 26, 2018, 11:58:26 PM
Hello I am new to this forum and trying to draw a GWR wheel as per the attached pdf (94814).  I have drawn up the hub and the rim ok and lofted the spokes.  The area that is causing me some confusion is where the spokes fillet into the Rim and the Hub.  At the hub the spoke has a 5" rad top and bottom but 3/4" at the sides.  At the Rim the spoke has a 4 1/2" rad top and bottom but 1" at the sides.

My question is how to do this variable radius.

I have contacted Don Cheke and attached his reply as a pdf

Thank you

Hi Julian,

If these don't help then use lofting with guide lines.
Use 3D Splines as the guides and sometimes as the profiles used in the loft.
Placement of the guides is important. ;D

There are also Smesh tools, these are also good for organic shapes.

Hello
I have tried to "Loft" the two forest green ellipses together using the red guidelines but keeping getting the attached error message.  Any hints as to what I am doing wrong would be appreciated

Thanks

I used four elliptical profiles and lofted the object in two separate pieces. No guidelines.

Hi Henry
Thanks for your reply I hadn’t thought of that as an option. Looks like you have got the shape that I am after which is great

Kind regards
Julian
