please help me about fill color in surface/solid

I want model electronic-capacitor for a simple 3D-PCB design prototype.
So I do it.

This is example of electronic-capacitor I want to model it.



I do model it using Cylinder Primitive. Just to make it simple.

Now I want to color it.
I do by Inspector:Fill Properties:Fill color. So I got the blue at a body and grey at 2 pins underbody.
But how do I fill color on top and side of body?
1.-top have round-circle of grey-metal color
2.- at 1-side have bar of grey-color mark for (-) polar , I just want to fill solid grey-color for simple , no text, no hatch.

I try to put 2D-line circle and straight-lint cross each other and fill color by Fill-tool.
Only on top-circle I can Fill grey color. But for 2D-line I can not.
It keep tell me "Valid hatch region not found" , even I placed line cross each other already. I just hope to fill color on solid within those region.


pic1. 2D circle on solid model


pic2. use fill tool to color on top of model


pic3. so I can fill color on top of model inside circle


pic4. next I try to fill another region on top of model after I draw 2D-line


pic5. "valid hatch region not found"


pic6. try again to fill color on side of cylinder model in 2D-line that I draw cross model


pic7. "Valid hatch region not found" again


pic8. my model and 2D-line that I've draw


pic9. my 2D-line only I hide the model.


I guess there must be things I misunderstand. Please let me know.
Also how to do it? How to fill color just like pictures before.

I new here. Is there better idea please tell me.
Thank so much!

Thank for your reply.

However for the deep select tool will select entire face just like this picture when I fill color.
Of course it not what I want.


I want just only fill color in some area of face. That is why I try to draw 2D in surface just hope to fill color in those area. But can't

Just like this , in that red color area.


It not exact like that. I just try to model from to this one. I don't need text in model only need the grey mark at side of model


Is there a simple way to do? Just like can I place 2D line on surface and fill color on those area?

hi,
a different way could be to create a draft like in picture 1 first.

next you can extrude 3 separate solids from the draft lines like in picture 2 (push pull tool will work. check "face snapping" in gripper settings!).

after assigning colors make a group of all solids or save as symbol.

regards
