Radial lines autocad
Isn't there a way to do this with the object tracking mode? Message 5 of Start outside the circle and use perpendicular osnap. Message 6 of Message 7 of Or draw from the center to a point on the circle I'll bet there are half a dozen more ways to do it. You gotta love this program.
Message 8 of Message 9 of This is AutoCAD Another line displays to indicate the ray. A temporary angular dimension displays as you rotate, and a preview image shows the selection rotating. If you selected Move To 2nd on the Options Bar, the second ray of rotation defines the location of the second member of the array.
Additional array members are placed using the same spacing. If you selected Move To Last, the second ray of rotation defines the location of the last member of the array. Additional array members are spaced equally between the first and last members. When the display of the arc extension line is not suppressed, a gap between the arc and arc extension line is made.
Depending on your dimension style settings, center marks and lines generate automatically for diameter and radius dimensions. They are created only if the dimension line is placed outside the circle or arc. The size of the centerline is the length of the centerline segment that extends outside the circle or arc. It is also the size of the gap between the center mark and the start of the centerline. Now rotate this line, using the opposite endpoint as the radius point.
Since this curve is to the right, rotate the line clockwise meaning you will have to enter a negative angle the amount of the delta of the curve. Next pick the other endpoint of the line, that is the startpoint of the ARC. Next pick the endpoint of the previous line segment. Your curve is complete. Now we have another curve to draw. This curve is also tangent, but in this case the previous entity is a curve. If the second curve goes in the same direction, it's called a compound curve, if the second curve goes in the opposite direction, it's called a reverse curve.
Notice that this curve is to the left, not the right, so this is a reverse curve. We need to do the same as above to find the center point, except rather than draw a perpendicular line, we need to draw a radial line from the previous curve. In this case we already have the green line in place, so extend it out past the last curve a bit. Now trim off the part that is inside the previous curve. It should look like this now.
Now use the. The other end is the center point for the next curve. Now rotate this line the amount of the delta, just like before. Because this curve is to the left, the rotation angle will be positive, not negative. Now it should look like the picture below the radius point is not shown since it is so far away.
