In Tekla Structures 2019 the part labels have new options, deleting clip planes has been made easier, and the listing of view windows has changed.
Part labels on the View Properties > Display dialog box now have new options.
Note that if you select the Selected or the Main part for selected option, you need to first apply the changes to the view when the view is selected. Then continue to select the objects for which you want to show the part labels.
Additionally, the Part label check box is now automatically selected when you click Add > to add a property to the Part label list.
You can now delete all the clip planes at once. To delete all the clip planes in all the open views, click View > Delete all clip planes .
When you now click Window to open the view list, the views are listed in alphabetical order.
