■ Things get weird when points, lines, or faces exceed the limit (15000). (Because memory is allocated with static memory. See the Trivia section for details.)

　

■ Dragging and dropping a large number of files at startup is rejected. (But is this due to DOS specifications? It's OK after startup.)

　

■ When slicing faces, if you slice a twisted quadrilateral face created by symmetric points on both left and right at the same time, the face disappears. (Countermeasures are very troublesome. But I don't think it happens if you work normally...)

　

■ If you shrink an object too much, the shape becomes strange. (Due to loss of precision in coordinates.)

　

■ If the object is too large, full-range zoom and selected-point zoom become abnormal. (Because the object is behind the camera. Make the object smaller or work in parallel projection.)

　

■ Exported rok files cannot be read by Metasequoia. (Can be loaded by Rokkaku Daioh. If you want to load in Metasequoia, use mqo format.)

　

■ While creating points, if you place the mouse over the locator window, the line being created is displayed in a strange place.

　

■ Even if two or more translucent polygons overlap in the same place, only one is displayed.

　

■ When creating a pipe on a symmetric point, the created pipe does not become symmetrized. (Create a pipe on one side's line and then symmetrize that pipe.)

　

■ In continuous face joining, if you select a line of a polygon sandwiched between symmetric points and try to join faces, only one side is joined. (Manually select the other side's line and perform continuous face joining again.)

　

■ In continuous face joining, if you select multiple lines and execute, sometimes they are not joined. (Select lines one by one and use it.)
