Line properties can be seen directly in the toolbar.
Set the properties as they should be. This goes for type, color, width, thickness, electrical line etc.
Mark the lines that should have these properties, and click the icon Transfer properties.
It is also possible to copy properties:
Mark the line with the desired properties, and click Copy properties. These properties can then be transferred to other lines as described above.
THANKYOU SO MUCH!!! I have been trying to figure this out for ages, lucky I found this forum!!
If you have a complete drawing that you want done, just highlight (using the line tool, without draw) the whole page and adjust to the desired settings and click Copy Properties!!!
I have found personally that 0.25 is too fine on A4 (even though Im young and can read ok) but it is still too faint for the average viewer. 0.35 seems to be the way to go.
Once again, thankyou!
