hole type?

hello,

i am fairly new to solidworks and i have been practicing by online tutorials and sample modeling.

i have a question about hole type from a practice example

its looking for M10 of something and it has strange dimensions

50 mm from top of the cylinder to the end of the segment and 59 mm of the whole thing

how do i express this in solidworks?

the dimensions i can play with are only from the end of the hole to a point where it starts to taper

can anyone please help?

thank you

bruce
