bolt dia is not shown correctly above 3/4" size in isometric

 

7/8" is 22.23 mm
try changing 24 to 22 or 23 in the BLTSET and equivalent diameter table

thanks pitch

so i need to change each dia of bolt to real conversion of inch. like (1.1/8 * 25.4) and forever.

If you look at the PDMS Bolting Method in PDMS Guides forum, there is a table of Bolt diameter equivalents
