We've integrated a new way to edit Symbols, Linestyles and Patterns. Simply rightclick any symbol/linestyle/pattern and choose 'Edit Symbol/linestyle/pattern...' to open the editor:
A new drawing will be opened in Pythagoras where you can adjust it to your likings. When the changes have been made you can save it, in this case as a symbol. You can choose to save it as a duplicate, give it a new name or you can overwrite the existing symbol in your library.
When the changes have been made, click 'OK' and you'll return to the original drawing where the symbol will be changed.
The same 'Edit' function can be found in the Symbol Manager:
For Line Styles, you only have the charactaristic 'Scale Dependent' to consider.
For Patterns you can change the angle and the scale dependency.
