Parallel with Full distance to Arc Tangency

[Hrki]

Hello,

 

why this don't "Snap to Tangent" like it should. Snap to Tangent it ON

 

 

This snap works but its make no sense

What command are you in?

 

Sometimes it is better to draw some construction lines rather than let AutoCAD choose where it wants to go.

Since you know by experience that the Tangent snap is not giving what you want, I would draw a temporary line.

 

Draw a line perpendicular to the line at A to the centre of the radius. Extend that line to the arc and offset the line B using the endpoint snap. Erase temporary line.

I tried to reproduce the issue, and the "tangent" point is (in my case at least) calculated from the endpoint of the original line. I thought the Perpendicular snap would do what the OP wants, but it doesn't register anywhere on the arc. Strangely enough, you can draw a line perpendicular to an arc.

 

I agree with Eldon, a temporary line should help to find the right point. Anything else adds complexity.

Thanks to CyberAngel's suggestion, my temporary line can be drawn in one go - draw the line perpendicular to A and then perpendicular to the arc. Job done in one.

Tangent will not work in this case. Your second image is the expected result. Tangency is relative to your picked base point.

Thank you guys for response! This helps me well!
