You’re right – the 4.10 dimension was accidentally referenced to the A-A section line. Go ahead with your plan, and use the dimensions from the model.

Thanks,

Howdy Andy,

On the print there is a dimension of 4.10 to the letter “ W “, but that is to the section line of A-A, not to the center of the part. I am getting 4.00 to the center of part. Is this correct? My plan is to put that letter where the model shows, unless you want different.//]

Yes, please include .02” chamfers around the .75”-diameter pads.

Also, please use the size from the model, for the “W” lettering. If it’s .274” tall in the model, go with that.

Thanks,
Andy//

Howdy Andy,

On this part there is a call-out for .02 chamfers on all sharp edges. Do you want the .75 dia pads chamfered as well? Also, note 6 asks for a 12 point letter “ W “. That is .125 tall according to my program, but the letter on the model is .274 tall. Which would you folks prefer?//]
