Click on the formula icon to bring up the window that allows the data entry to mark the point along the Sleeve Centerline that marks the edge of the sleevecap. Click on “Measurements” under Input data, then double click on “arm_shoulder_tip_to_armfold_line” to use that measurement to define the point. '''Figure 7''' illustrates this action.

Now that the edge of the sleevecap has been located, the “point along perpendicular” tool will be used to draft the bicep line. A perpendicular line which is 1 1/2” plus half of the biceps measurement will be drawn on each side of the sleeve centerline. Select the “point along perpendicular“ tool, then select point A2 as the first point of line and point A as the second point of line. The Help Sentence will indicate the time to select each point. The “point along perpendicular” window ('''figure 8''') will show the formula. It will also show that the label A3 was assigned to the point created and that the “additional angle degrees will be left at the default value of 0 degrees. That corresponds to the line at a right angle to the vertical Sleeve Centerline to the left side. <!--T:9-->

To construct the formula for creating a line of the required length, double click on the f(x) label in the “point along perpendicular” tool window. Double click on the “arm_above_elbow_circ” measurement from the measurement table then use the keyboard and arrow keys to complete the formula to look like this: 1.5 + (arm_above_elbow_circ / 2). The 1.5 (or 1 ½) inches included in the formula represents the basic fitting ease as described on page 72 of the 1977 revised edition or or the Ease as described on page 80 of the 2016 second edition of the McCunn book. '''Figure 9''' shows the formula data entry window.

Click “OK” to exit the data entry window and click “OK” to exit the “point along perpendicular” tool window. You should see points A, A1, A2, and A3 along with the sleeve centerline and the left half of the biceps line. '''Figure 10''' shows how your Valentina main window will look after steps performed so far in this tutorial.
