Position simple drawing interpretation.

Its ISO drawing

If i do a Thrue Position with nominals to CAD is this ok ?
And i should not use bore pattern ?
I think dimensions 44 and 44 are not important for me in this case ?
if yes how this should look ?
I think it's not a case to use of bore pattern becouse there is no "CZ" but ... may i miss something ?

CZ is not used for patterns, but for sectioned features ( aka cylinder divided by slots ).

Here you have to use pattern with respect of base A,B,C

Here is the norm ISO 5458 https://www.iso.org/standard/65559.html

Damian, I this case you have Datum Reference Frame which constrains all Degrees of Freedom. The only difference you'll see if you do a bore pattern is, that you'll get 1 result (the worst).
Just for the information, even if the DRF wouldn't be completely constrained, it's a bore pattern (CZ), since there is (M) in the tolerance frame. At least that's true for ISO 2692:2014. Source -> https://www.linkedin.com/pulse/individu ... 2-marczak/

For basic dimensions, the way it's shown isn't OK. You have 2 options:
- add/modify basic dimensions so that they originate from datums (B and C)
or
- delete all basic dimensions from the drawing and add a note that basic dimensions are to be taken from CAD model.

No basic dimensions with respect to ABC .... Wonder...

Thank you a lot Martin

There is no tolerance becouse constructor forgot about it
