Hello!
I just learned you can color edges by axis (sweet!). Some questions along those lines:
a) Is there a way to get circle and arc edges to color? (or because it’s a bunch of tiny segments, there would just be one red dot where it touched the axis, etc.)? (I made a cylinder and can get the middle lines to be green, but I can’t get the end circles to be anything but black.)
b) Is there a way to color a face if it’s axis-oriented? (So, front-view faces are all the same color, right view faces are all the same color, etc. I know that diagonal faces won’t be colored.)
c) Using the color edges by axis, if I see one that isn’t colored that should be, can the program align that for me some how, or do I erase that line and redraw it? How do I fix those?)
You could rotate the circle so there are edges parallel with the axes. that would take care of four edges. By definition, none of the other edges will be anything other then black since none of the other edges are parallel to an axis.
You can manually paint the faces but there’s no way to set them to be colored based on the axis to which they are parallel. Besides, what color would be used for example on a face the lies parallel to the ground plane? Red? Green?
SketchUp is good but it can’t read your mind. If you create an off-axis line, there’s no way for SketchUp to know it is supposed to be on axis. You need to either rotate the edge to be on axis or perhaps redrawing it will be more expedient. And if the edge was supposed to be on axis in the first place, draw it that way and avoid having to repair the geometry afterward.
And the picture of the circle on the axis is great. That way, I can tell it’s definitely flat (reds across from each other, greens across from each other, for example).
I’m working toward better designing. That’s why all these questions. My model printed fine, but I went back and error-checked it and it surprised me by how many it came up with. So, I’m trying to learn.
To be sure “things” are flat, use the new axis (X=RightArrow, Y=LeftArrow, Z=UpArrow) & planar (DownArrow) inference locking keys, while you are drawing “things.”
BTW, Polygons and Rectangles (drawn with those tools,) also will show some edges colored by axis.
Exactly.
@leaning Faces are associated to an axis through their normal & anti-normal vectors. So a face lying flat upon the XY plane (regardless of whether any of it’s edges are parallel to either X or Y axis,) has a face.normal == Z_AXIS and it’s inverse (anti-normal) face.normal.reverse == Z_AXIS.reverse.
So such a face’s axis association color would be some kind of blue.
But, faces have both a front color and a back color, (and the back color is shaded by convention.) So any automatic “coloring” feature would likely need to make the front faces some axis tint, and the back color an axis shade. You would also need to change the style so that any non-aligned faces use the tint and shade of a color not associated with the 3 axis.
How are you rotating the circle? I suppose not by its center. Maybe you should spend some time with the very fundamental tools instead of worrying about template and tool names and such. It appears yours is a scatter gun approach to learning SketchUp. You should focus on one tool at a time.
Yep.
But everyone learns differently and everyone’s brain works differently. “Scatter gun” is my style.
And I’ve already learned my lesson about that requests forum. I can’t delete it, and it’s an ugly eyesore that we are all stuck with, and an example of what not to do, but no bearing at all on this topic.
And like I said, I’ll get the circle thing figured out.
