Select the polyline. Right click. Select “Properties”. The length of the polyline is displayed on the Properties window. Note: the length is 45.7080 mm which is longer than the specification of 31.25 mm. Rescaling the design to get the right length. Calculate the scaling factor by using the formula . The calculated scaling factor should be 0.683687757. Select the design. Press the tool button in the tool bar. “scaling” Select any point in the design to choose a base point. Type in the scaling factor 0.683687757 and press “Enter”. Verify that the design is 31.25 mm by checking its length in the Properties window. Add dimension labels. Make a copy of the design pattern.
