CAD Question 2 — How does CAD translate a distance along a diagonal line?

At the position of the red line, draw a circle with a radius of 25; it should intersect the green line there.

I want the distance between the center lines of the two circles, namely the red line and the green line, to be 25 mm in a 60° direction; in other words, the value of 28.9 should correspond to 25 mm. (And even if a circle were drawn, it shouldn’t be 25mm – it should be 50mm.) The position of the green line is already incorrect; how is it possible for the circle to intersect that green line?
There’s a red line now, right? Do we have the 60-degree line now? If you draw a circle with a radius of 25, then the diameter must be 50, right? Is it hard to understand?
You can also extend the vertex of the red line, draw a line 25 units long along that red line, then rotate the vertex by 60° to find the positioning point for the translation.
Practice the offset and length truncation methods
Is there an exact angle between the center of the green circle and the center of the red circle?
Draw a perpendicular line to the diagonal at the center of the red line; the spacing between these perpendicular lines should be 25 mm. Then copy the red line to the focus of those perpendicular lines, so that the distance remains 25 mm.
First, locate the points, capture them directly, and then move the circle. That’s absolutely right.
