Editing drawings, especially general arrangement drawings, may take some time. To ensure that the editing work is not lost when an application error occurs, the drawing autosave was improved. Now the autosave for drawings is also triggered automatically at an interval defined in the Options dialog on the General page.

Previously, autosaving was done automatically for the model only, either at defined intervals or after you had created a defined number of drawings. Autosaving after creating a certain number of drawings is still available as a safety measure.

During autosave, the model is saved in the model \autosave folder as before, for example, in C:\TeklaStructuresModels\autosave\House. The drawing is saved in the model autosave folder in the \drawings subfolder, for example, C:\TeklaStructuresModels\autosave\House\drawings.

There will always be at least one model autosave when a drawing is autosaved. Subsequent drawing autosaves will not trigger a model autosave unless there are model modifications.

When you close a drawing normally (with or without saving), the drawing autosave file is deleted. Additionally, when you save a model, both model and drawing autosaves are deleted. This ensures that there is only one autosaved drawing at a time. When you close the model, model autosaves are deleted unless the advanced option XS_KEEP_AUTOSAVE_FILES_ON_EXIT_WHEN_NOT_SAVING is set to TRUE.

When a Tekla Structures application error occurs, opening the active model prompts you to open either the manually or automatically saved model version, as before. The dialog has been improved to include the following information:

• The name of the autosaved drawing, if any

• The path to the autosaved version of the model and the autosaving time

• The path to the last manually saved version of the model and the saving time

If you select Autosaved to restore the autosaved version of the model, and there is an autosaved drawing, Tekla Structures opens the autosaved model and the drawing automatically.

When you open the drawing, a notification appears indicating that the autosaved drawing has been opened and saved. Check the drawing and choose if you want to keep or discard that version. If you do not want to restore the autosaved drawing, you can open the Drawing versions feature and select a previous version and save that instead. If you want to keep it, you should save both the drawing and the model as soon as possible.

You can access manually saved drawing versions using the Drawing versions feature in Document manager. You are required to exit the autosaved drawing with a save, which adds the autosaved drawing as a new version. Then you can switch between all existing drawing versions freely.
