 Top  Previous  Next

Snap to the intersection of the selected edge and a tangent.

 

 

Since this function operates in full 3D, the tangent may pass above or below the selected edge and not actually intersect. In this case the closest point to the tangent line on the selected edge will be picked.

 

This convention must be emphasized. The intersection point will not be selected on the tangent line: it will be selected on the intersection line.

 

Using this feature is a two step process. When you click on the Intersect Snap button ID_SNAP_INTERSECTION you will be prompted as follows:

 

1.First select a tangent line.
2.Then select the edge you want to intersect the tangent with. The point will be selected on this line.

 

The edge nearest the pickbox will be selected.

 

The pick-box must be located over an entity or construction line.

 

This function can be used to locate points at the intersection of the tangent and the projection of the selected edge.

 

 

Once a point is selected, intersection snap is automatically cancelled. Intersection snap can be cancelled at any time by pressing the escape key (Esc) or right click the mouse.
