In this tutorial you will find how to create flexed text in SolidWorks.
Create a sketch on a plane(Front Plane for example)
Starting from the origin, create a construction line with any dimension.
Draw some text on that construction line.
Extrude the text at a random height(1 mm for example).
Go to Insert -> Features -> Flex
From the Flex command tree choose Bending on the Flex Input tab.
Select the text you created earlier.
Enter an angle and click OK.
The result should be similar with the image below.
