00:03
In a Fusion drawing, you can use datum identifier and feature control frame symbols to specify tolerances between two surfaces.
00:12
For example, you may want to represent the parallelism of two sides of an object.
00:18
Start with a drawing open in the Drawing workspace and zoom in on the area that you want to work in.
00:25
In this example, you want to represent the parallelism between the left and right sides, or front and back, of the casing,
00:32
so zoom into the side view.
00:36
First, add the datum identifier.
00:39
From the toolbar, Symbols group, click Datum Identifier.
00:44
Then, in the drawing, select the left edge of the casing.
00:48
Click to specify the start point, then click again to place the datum identifier.
00:54
Right-click and select Continue.
00:58
A Datum Identifier dialog opens.
01:02
In this example, no datum note or thread note is required, so click OK to close the dialog.
01:09
Next, add the feature control frame.
01:12
From the Symbols group, click Feature Control Frame.
01:16
In the drawing, select the edge of the object that you want to attach it to; in this case, the right edge of the casing.
01:25
Specify a start point, then click to place the leader.
01:29
Right-click and select Continue to place the feature control frame.
01:34
The Feature Control Frame dialog opens, where you can add tolerances and symbols.
01:40
Click Reset to clear the values.
01:44
In this case, since the two surfaces need to be parallel within a tolerance of plus or minus 0.005 inches,
01:52
set the Characteristic to Parallelism.
01:57
In the Tolerance drop-down, select the Plus/Minus symbol, and then enter a value of 0.005 inches.
02:07
For the First datum, instead of entering a value, type A to represent the A datum.
02:14
You can add more information to the feature control frame, if needed, but this is enough for parallelism.
02:21
Click OK.
02:23
This adds a parallelism feature control frame to the drawing and indicates to the manufacturer that these surfaces are critical to the part.
