The TechDraw Symbol tool inserts a Symbol object. A Symbol is a stripped down view that contains only a single SVG file complying with the svg-tiny specification (see TechDraw Templates).

A Symbol can be anything that helps annotate a drawing and that doesn't need to be further modified, it may however contain editable texts.

introduced in 1.0: The TechDraw View tool can also create a Symbol.

Compass rose added to the drawing page; this symbol is available by installing the "symbols_library" addon with the Addon Manager

1. If there are multiple drawing pages in the document: optionally activate the desired page by selecting it in the Tree view.
2. Select the TechDraw → TechDraw Views → Insert SVG Symbol option from the menu.
3. If there are multiple drawing pages in the document and you have not yet activated a page, the Page Chooser dialog box opens:
   1. Select the desired page.
   2. Press the OK button.
4. A file browser opens.
5. Select an SVG file.
6. A symbol is inserted.
