V dual wheel and extrusion problem

Something is off on the wheel model. 45degrees should be a driving dimension.

 

Odd. maybe some decimal stack up somewhere throwing the angle off. I highly doubt the 45 is off on the actual part though. This is why I suggest changing the model dimension to driving. Maybe make the width driven.

Wait. What? How do you know China used the drawings? Even if they did, the drawings are Openbuilds drawings for Openbuilds to interact with manufactures that Openbuilds chooses for Openbuilds to receive a product in which they can inspect and approve before Openbuilds supplies those products to Openbuilds customers that buy the product directly from Openbuilds.
If a Chinese company is reproducing and selling products based on drawings from another company without direct human interaction about design and manufacturing consideration with that company or even approval and endorsement then the Chinese company is directly responsible to the customer for making a crap product.
Beware of knockoffs?

 

I have to add that the Chinese that I have dealt with have been very professional and made it apparent that customer satisfaction was the number one priority. So no offense to the Chinese.

 

I didn't know if you were guessing or making a statement. Regardless of the drawing, you're going to receive quality controlled products from the Openbuilds part store. If you choose to go with some place else for product clones then your taking a chance at the final product. Just sayin. I know that there are a lot of Chinese suppliers that sell a lot of different products. They keep their eyes on the market and when they spot products like the OB wheels they jump at their manufactures to make lots for them. If it's a good manufacturer then the supplier will receive a product that'll suffice to the market. If the manufacturer isn't so bright then the supplier will get crap and have to try and peddle that. Even in this case, the supplier with the good manufacturer may have the employees responsible for great products move on only to be replaced by noobs and/or low cost failures and the supplier with a poor manufacturing source can eventually see great products. I'm almost tempted to move to China for this reason.
End of rant

 

For this you have to set the 45degree to a driving dimension. ... That means that no matter what other dimension changes the 45degrees is set in stone. I suggested before that you make the width the flexible driven dimension. The reason is that your wheel centerline axis will not change.

Now, I haven't played with the OB parts in solidworks in a long time and I'm just waiting on someone who has to chime in here. Otherwise I'll do it tomorrow at work to help you out.

OD, wheel contact angle, and width are the same.
