   FreeCAD Part Design Video Tutorial Technical drawing is below..Video contains how to design this part in FreeCAD workbench. If you want to practice, you can watch all steps in video then you can create same drawing.

Drawing contains

• How to decide starting plane in 2D sketch
• Creating plane according to technical drawing
• Using 2D sketch constraints relations
• Creating constraints
• Using Isometric View to create a sketch.
• Adding Dimensions
• Creating sketch without external geometry
• Creating pad and pocket in symmetric to plane.
• How to use symmetry button in FreeCAD 2D sketch
• How to refine parts

 VIDEO TUTORIAL OF THIS PART

If you want see all these steps, I recommend to watch below video. Subscribe my youtube channel to see more CAD tutorials. I share tutorial videos regularly.

FreeCAD Sketcher Constrain Lock

 Constraint Lock applies  Horizontal distance and Vertical distance constraints to selected vertices (points) in the sketch. If a single vertex is selected, the horizontal and vertical distance constraints will refer to the sketch origin point. If two or more points are selected, horizontal and vertical distance constraints will be added for each pair of points.

 It provides easiness which helps to create desired constraints in 2D sketch. Lock constraint button is located on top sides of constraints set.

 This is the picture of lock constraint 

TECHNICAL DRAWING OF VIDEO TUTORIAL

  How to use lock constraint ? Read these 3 steps to use it.

1- Select one or more vertices (points) in the sketch.

2-Press the Sketcher Constrain lock button.

3-To edit the constraints values, double-click on a constraint value in the 3D view, or double-click on the constraint or right-click and select Edit value in the Constraint list in the Tasks tab.

 This is technical drawing is created by using lock constraint button.
