# 3.3.9: Cross Section Matcher

Use the **“Cross Section Matcher”**-component in case you want to find the first profile from a given list that provides equal or higher resistance compared to a given custom profile (see fig. 3.3.9.1). The **“CSMatch”**-component takes a cross section and a list of cross sections as input. Traversing the list starting from the first element it proceeds until an appropriate profile is found which is returned as the result.
