Context

Context provide the ability to select “snappable” items and create snap helpers from selected items, like intersections / perpendicular, average, see Helpers.

Select items

Important

In order to select snappable items, you must hold SHIFT
while pressing left mouse over an active snap item (highlight yellow).

Remove selected items

In order to remove last selected item, use BACK SPACE.
To remove all items, use SHIFT + BACK SPACE

Evaluate context and add new helpers

Important

Context evaluation depends on the view :
In orthographic view you’ll get intersections based on view angle
In perspective view, you’ll get closest points

Usage : select items, then use shortcut H for helpers, A for average

  • Line / line intersection, require at least 2+ lines

  • Line / plane intersection, require one line and a face

  • Nearest point on line / plane (perpendicular), require one point and one line

  • Nearest point on plane (perpendicular, require one point and a face

  • Line between 2 points, require 2 points

  • Face normal, require one face

  • Average of selected points location (shortcut A) require at least one item
