When using TCE values in the Lens Data Editor, the corresponding surface Thickness must use a Thermal Solve in the Multi-Configuration operand. However, this solve type cannot be set for the first configuration. Therefore, when setting up a new Universal Plot to display a variation in temperature, one should always choose a configuration where the Thermal Solves are present.

What can be sometimes confusing is that if you choose the first configuration and have surfaces with glass materials, these Thicknesses will be affected by the temperature directly as they do not require a Thermal Solve. Consequently, one might observe a concluding plot, which in fact did not consider the effect on surfaces with custom TCE values.

In the following dummy example, I'm showing two curves ploted for configuration 1 (no Thermal Solve) and 2 (with Thermal Solve). Although the curve for Config. 1 looks normal, it doesn't consider the thermal effects on surface 3 (TCE = 50) shown in Config. 2.
