Release Notes

2024/12/07 ver2.0.8

• [Mandala] In Mac version, converting an oval in Mandala mode into a template part by pressing F9 key crashes.

• [Layer] Fixed an issue with layer list that when only one layer is visible, performing "Show all layers" from the right-click menu causes an error.

• [Printing] Fixed an issue with printing in white background mode that the background is printed as very thin gray rather than white.

• [Demo data] Fixed an issue with the demo data that the pattern on the left doesn't have the thumb hole in the front leather.

2024/12/02 ver2.0.7

• [Oval] An oval is now stored as four Bezier curves from this version to support rotation and use in Mandala.

• [Painted Part] When converting selected shapes into a template object, closed potions will be converted to a template path object filled with the selected color.

• [Demo] A demo project is loaded at startup by default. (Can be disabled.)

• [Line Palette] Increased the number of line palettes from 10 to 40.

• [Line Palette] Enhanced color selection in the line palette editor.

• [DFX/SVG Export] Optimized the order of shapes to be exported as DFX or SVG.

• [Bezier Curves] Changed the behavior of symmetrical Bezier control point editing (again). If there is only one Bezier curve connected, [SHIFT]+dragging a Bezier control point works as symmetric mode.

• [French Pricking Iron] Fixed the length issue with French pricking iron when the width is set to 0 (for cutting machines).

• [Performance] Improved the speed performance by skipping the intersection calculations for obviously not intersecting shapes.

2024/11/15 ver2.0.1

• [Auto Stitching] Improved the algorithm for the auto stitching pitch calculations. It's much faster from this version.

• [Internationalization] Fixed some typos, etc.

2024/11/14 ver2.0.0

• [SVG/DX Export] Added a checkbox in the SVG/DXF export form to convert dotted lines and dashed lines as solid line. (Dotted or dashed lines appears weird when imported into xTool XCS).

• [Bezier Curve] Splitting a Bezier curve by [ALT]+click now works only when the target curve is selected.

• [Bezier Curve] Synchronized Bezier control point editing for the two jointed curves (Hold SHIFT key when dragging) now works only when both curves are selected.
