3DS Max, Makerbot desktop and sizing and scaling issues

[Anonymous]

When I'm creating model in 3DS max and import them into maker bot to send the them to print I got wrong or bad size I'm asking for some advice here what my grid spacing and unit setup looks like. The units in Makerbot desktop what the best way to be 100% accurate thanks
