Sketch Dimensions Activity
This Fusion 360 tutorial demonstrates how to apply Sketch Dimensions to a 2D sketch to fully define its geometry [00:00]. The video covers different ways the dimension tool works, including:
Horizontal and vertical distance components of an angled line, as well as the aligned length [00:45].
Dimensioning between two points to get horizontal, vertical, or direct distance [01:36].
Dimensioning between a line and a point to get the perpendicular distance [02:30].
Dimensioning the angle between two non-parallel lines [02:54] or the distance between two parallel lines [06:42].
It also introduces the concept of a Driven (Reference) Dimension, which is a measurement shown for information only and does not control the sketch's size, preventing over-constraining [04:24].
