Is the line width feature broken?
- You might need to zoom in to see the width.
- The line width is not shown when Draft Mode is enabled.
Why does exporting a PDF produce a blank page?
- You need to select a paper format (e.g. A4) in 'Current Drawing Preferences'.
Is the unit precision broken?
- "Current Drawing Preferences -> Units" affects the statusbar and info tools
- "Current Drawing Preferences -> Dimensions" affects the dimension tools
Why do I not see the text associated with dimensions?
- You might need to raise the value of Current Drawing Preferences -> Dimensions -> Text Height
- You might also need to adjust the value of Current Drawing Preferences -> Dimensions -> General Scale
