# C.2.50 No Turnouts|Structures are available.

The Update Turnouts and Structures command updates (or refreshes) selected turnouts, sectional tracks and structures on your layout with the current definitions from the loaded parameter files (Section 2.5.5). Each selected object that is found in a parameter file is updated with the current definition.

If an object can not be found or if the new definition does not fit (same number of endpoints and all the endpoints have the same position and angle) then a dialog is displayed which contains suitable definitions that you can choose from. In the case of turnouts, this list is populated with turnouts having the same number of endpoints as the selected turnout. If turnouts with the same number of endpoints exist then this message is displayed.

Refer to section 2.9.9 for detail.
