Dimensioning 3D models on 2D projections

In this video, you will add dimensions to 2D drawings that were projected from a 3D model. …Then you will alter the 3D model and use the annotation monitor to alert you if …any associations have been broken. You will then re-associate any …orphan-dimensioned objects, to maintain the veracity of the drawing. …Open the Mechanical Part 3 project file, and go to the Annotate Tab. …Select the Linear Dimension tool from the Flyout and Zoom In to the front view.…

Make sure object snap is on and snap to these two end points. …Place the dimension object somewhere above the hole. …Let's go ahead and open the Flyout and choose Radius. …Click on this Inner Radius, and locate a dimension object, do that again over here. …And then, up here in the top view, let's do this one more time on this whole.…

Okay, now that we've added some dimensions, let's turn on the Annotation …Monitor which is located down here on the Status Bar. …This is going to alert us if any of our dimensions become disassociated from the …
