If you ever model curved or circular structures with AutoCAD Arch. | MEP and have started your company template with the OTB Arch. or MEP template you may run into this issue. Below I have modeled a circular concrete tank and then cut a Section right through the center of the tank. As you can see the inner diameter of the tank is 100'-0" but when I measure the Section it measures 99'-11_1/16". This is NO GOOD!!
After the jump see how to fix this issue...
