Circle refuses to create as i want

[Karol-Or]

I want to draw a circle centered on the origin and reaching to the intersection of the vertical and horizontal line. i can't, it jumps to the circle already drawn. i tried to change snap settings.

I found the reason, they don't lie on the same plane. i can't delete the post, why?

Hi,

have you looked to the geometry from another perspective?

This shows the endpoint of the "vertical line" (which is here the shorter line) has a different Z-value compared to the center of the circle.

When you now start command _CIRCLE, show first the center point (= center of your existing circle) you are now asked for the radius ==> and this distance (if you show a new point) is measured between the previous point (center of the existing circle) and the second point.

Well ... the problem is that the different Z-value influence the distance between point1 and point2 ==> it's not what you see 2-dimensional (from your to view).

Distance between these 2 points in 3D-space: 55.2254

Distance between these 2 points only 2D measured: 46.5457

And that's why the radius is larger than you thought.

In that case, you could use APParent-intersection object snap to get the result that I expect you want.

You could have [within a certain time limit] Edited the original message and replaced its contents with some kind of "never-mind" wording.  And you could pick on the "Report" button at lower left, and ask the Moderator to remove it, but that may not be possible once anyone has Replied to it.
