About analysis part properties
You can view, define, or modify analysis part properties before or after creating analysis models. You can define analysis part properties independently from analysis models, or modify them according to an analysis model. Analysis parts can have different properties in different analysis models.
You can define analysis properties for parts before you create analysis models. Tekla Structures applies the analysis part properties when the parts are added to an analysis model. You can also modify analysis part properties after you have created analysis models.
If you view the analysis properties of a part before you have modified the properties or created any analysis models, Tekla Structures displays the analysis properties according to the part type. For example, all steel beams first have identical analysis properties. These settings are called current analysis properties.
If you modify the analysis properties of a part before you create analysis models, Tekla Structures saves the modified settings as the default analysis properties of the part in the AnalysisPartDefaults.db6 file under the current model folder. These default analysis properties override the current analysis properties and will be used when you add the part to an analysis model.
When you create analysis models and then view the analysis properties of a part, Tekla Structures displays the properties according to the selected analysis model. If you do not have an analysis model selected in the Analysis & Design Models dialog box, Tekla Structures displays the current analysis properties for unchanged parts and the default analysis properties for modified parts.
