- In this video, we will loft…a frame element that follows this curved path.…Before we can loft the element, however,…we need to draw in the cross sections.…We have some information here in the 2D layer…that we can use in regards to the size of the frame.…I'll zoom in here and let's measure a distance.…I'll type DI for dist, Enter.…Using object snap, I'll click here and here.…
It's 12 millimeters across.…We need to have a circle up here…that's got a diameter of 12.…To place that circle, we need to think about…the user coordinates system in it's orientation.…Right now, it is oriented flat…with respect to this triangle.…We need to rotate that system 90 degrees about the Y axis.…Type UCS, Enter, Y, Enter, Enter.…
Now that's the correct orientation so that the X Y plane…is matching the direction I want to draw the circle in.…Type CI for circle, specify the center point right there,…use the diameter option, and type 12, Enter.…That's how the frame is going to…terminate up there in a circle.…Over here, it looks like the frame element gets thicker.…
