Reversed? Is it not a matter of tase? But thanks for the idea, that’s smart.
May I ask what kind of style you guys prefer? But on the other hand you probably never draw in 2D.
No! It’s not a matter of taste. Only front faces should be exposed.
This kind of question reinforces why it has been suggested by several people that you should take time to correctly learn to use the program.
My models are only 2D for a few seconds when I first start them. It’s a 3D modeling tool and I model in 3D.
I don’t understand why. But whatever.
I found it.
Would anyone here like to make a template and put up here that you recommend has the best style and colors? 
I’m getting a hand of how to choose style and understand that you should simple move a component above a face so you see it clearly.
Thanks everybody!
One thing I wonder though. Will there be problems when I turn my 2D drawing into 3D…
Because then not everything is on the exact same level.
And I wonder how my drawings has become this way. And how come the components disappear sometimes when viewing even if I have placed it “On face”.
You need to go to the The Learning Center. and learn the Basics. In the long run you will save time trying to figure things out and you will not make as many mistakes. At this point it may be best to start with a fresh drawing AFTER spending time at the Learning Center and the videos here at The SketchUp You Tube Channel!
Unfortunately, you are sort of off the beaten path when it comes to your workflow. MOST workflows have desiderata start in 3D and only generate 2D at the end. You are right… the steps you will need to do to prevent z-fighting will be at odds with creating a proper 3D model.
But these problems can happen when drawing in 3D first too, right?
It does happen, but most often when someone creates something without depth (i.e. a 2D surface in their 3D model). Proper 3D modeling means that everything is modeled as though it has some volume… so nothing should exist as a 2D item.
Your posts like this make it sound like you are resistant to learning to use SketchUp correctly. I enjoy teaching SketchUp users who are willing to learn but I don’t have time for those who won’t.
@DaveR hit the nail on the head, I think. The REAL way to prevent the issue is to model in 3D. As has been said, you CAN use SketchUp for 2D drawing, but all of it - the tools, the orbit system, the inferencing - was created and intended to be used to model in 3D space.
Ok. I guess I am the only one drawing in both 2D and 3D then, and I like that. I have made a lot of 2D furniture in the sizes that I used to draw before with pen and paper, some might be typical Swedish measures. I use the 2D drawings to make them into jpg images, fix them in Affinity Photo afterwards (like adding texts to the rooms) and but them up on my website.
So it’s usually just the 3D drawings that I save as SketchUp files. But I also put up 2D drawings in my SketchUp 3D Warehouse, but that’s just because some houses I don’t want to spend time drawing in 3D as well, but maybe someone like the floor plan and want to build it in 3D or get inspiration at least.
Maybe there is another program that is made for making both 2D and 3D drawings…
I draw 2d on planes (faces) separated by 12" vertically ( blue ), place the various planes both in a group and on a tag.
Set up the group/tag combos in scenes to allow you to easily select on which plane,tag,group you want to work on.
Just remember to dbl click on the groups when you edit or draw on them.
This keeps everything neatly organized and automatically keeps you out of trouble if you pay attention to what you’re doing.
Use guides on the blue axis to determine if an item is on the surface or not. If it’s not you,ll see the guide penetrating the surface below the item. Use the guide to help you place items on surfaces properly.
When you set the camera to parallel projection and top view you will see all of your drawing combined as if it were a single drawing. Make a scene of this setup so you can return to it with ease.
Do not orbit when in Parallel projection if you can help it. Just makes a mess of things.
I saw this, but can not find it in my program. I have SketchUp 17.3.116.
Tags is the current name for layers.
You have 17 so you have Layers.
Tags was called Layers then. Under the window menu still. I m not sure if Trays we’re in use back then or not in 17. If you don’t see the trays, everything is under the window menu.
I forgot one thing. Add translucent materials (glass) to each plane so you can see through them to be able to understand the relationships from one plane to another.
Eventually, I do turn these design drawings into 3D. Believe it or not, I find it easier, after 40 years of Acad to design INITIALLY in 2D. It’s either SU in 2
D or Acad for the first planning stage. As far as I’m concerned, it’s easier to revise the 2D drawings. If the project goes south, less time is lost.
