after 10 years working with Sketchup I still have some problems that no matter how much the program evolves in its updates, they persist.
do not work with curves, only with segments of lines
there is no tool to measure curved distances
there is no shading of curved surfaces and transparency combined in the same style (it is as if the hidden line style could be shaded)
4) New style: It would be great if there was a style that would brighten the colors of the materials but not affect the lines. (this would be useful for keeping the color textures of the drawings in the documentation, showing the materials used in Sketchup and saving on printing the documents without affecting the ink quality of the lines in the drawings)
5) In LayOut, Hybrid mode that works with this new style (4) and shows the transparency of materials
