Adding Dimensions to the Sketch
1
Right-click in the Graphics window, and from the context menu choose Dimension () to enter the smart dimension mode.
The smart dimension tool works similarly to the smart constraint tool: you start by selecting entities, then either apply the suggested dimension, or change it first, and finally enter a dimension value before continuing with adding more dimensions.
2
From the Graphics window, select the edge highlighted below.
3
To apply the suggested Distance dimension, click above the edge to place its symbol.
The Distance 1 node is added to the geometry sequence, and the Settings window for Distance is displayed where you can start typing directly to edit the value.
4
In the Settings for Distance, in the Distance field enter 65[mm].
5
Click Build Selected (), or press F7, to build the geometry using the new value.
6
Select the circular arc highlighted below.
7
Click to apply the suggested Radius constraint.
8
In the Settings for Radius, in the Radius field enter 4[mm].
9
Press F7 to build the geometry.
10
Select the two edges highlighted below.
11
Click somewhere between the edges to apply the suggested Angle dimension.
12
In the Settings for Angle, in the Angle field enter 3[deg].
13
Press F7 to build the geometry.
14
Repeat Steps 2–13 to add a distance, a radius, and an angle dimension for the edges on the left side of the bracket, highlighted in the following figure. Use the following dimension values: 30[mm] for the Distance dimension applied to the vertical edge, 6[mm] for the arc radius, and 20[deg] for the angle.
When done your drawing should look similar to the one displayed below.
The applied constraints and dimensions are now sufficient to define the shape, but the two translational rigid body degrees of freedom are not yet constrained.
15
Test to move around the geometry by dragging an edge or vertex on the canvas. Note that it is not possible to rotate it due to the applied Vertical constraint. Restore the geometry if needed by pressing Ctrl+Z.
16
As the smart dimension mode is still active you can select the vertex below for applying the last dimension that will constrain the remaining degrees of freedom.
17
Click close to the vertex to place the symbol for the suggested Position dimension.
18
In the settings for Position, x and y coordinates text fields enter -35[mm] and 15[mm], respectively.
19
Press F7 to build the geometry.
The geometry is now fully defined. This is also indicated by the black color of the entities.
20
Right-click in the Graphics window, and from the context menu choose Dimension to exit the smart dimension tool.
