Each time Valentina creates a new pattern piece a base point is created. Because “McCunn-basic-sleeve” is the first pattern piece in the pattern file

'''McCunn method - step 1)''' The first line, which is the Sleeve Centerline (shown in '''Figure 1'''), may be seen as a line from the shoulder point to the wrist. Draft this line using the “point at distance and angle” tool.
That tool is found on the Valentina Point sub menu. Click on point A and drag the rubber band line in a downward direction. The angle and distance need not initially be precise because a window (as shown in '''Figure 4''') will pop up and provide the opportunity to make adjustments to the values.
<!--T:5-->
Use the Angle data entry box on this window to ensure that the angle is 270 degrees exactly.

The length of the line is represented as a numerical length (which is a result of the length the user dragged the rubber band line). Delete that numerical value and click on the function icon. The function icon may be recognized by the label f(x).

As a result of clicking the function icon, a formula window will appear (as represented in '''Figure 5''') to provide options for creating a formula. Options for data that may be included in the formula include the items listed on the left side of the window under the words Input data. In this case, a measurement will be chosen, specifically “arm_shoulder_tip_to_wrist_bent” which corresponds to the measurement called “arm length” in the McCunn method. The point at the wrist end of this line is automatically labeled A1.
