The default settings in SCAL2 result in squared off points when shadowing shapes or svg files. The image below shows two stars: a plain star, and an identical star with the default shadow.
This can be fixed by changing the default settings. From the menu, select Edit/Preferences. The Preference dialog box will appear. Deselect the “Default Shadowing” check box.
This is also where you can select other preferences, such as the SVG dpi (90 for Inkscape or 72 for Adobe Illustrator) and “Keep Proportions”.
The image below shows the same two stars without the “Default Shadowing”. This appears to work for both the SCAL shapes and imported svg files. It doesn’t appear to make a change in the disappearing text though.
