While putting a door on that space, I found complexity of viewing. The wall making hindrance. What way makes it easy? Please notice this…
I can´t see anything but I noticed that your model has a lot of back faces exposed, all the faces should be white, you can either right click on a blue face or more and select reverse faces or right click on a white face and select orient faces.
Should I keep the interior in blue color or turn all(interior + exterior) wall in white color?
You should have different colors for front and back faces, otherwise you won’t be able to tell if they’re well oriented, you can change the color of the front and back faces on the styles tray, some people use visually strong colors as back faces like a bright pink or green so it’s easier to notice the back faces. It’s just visible in monochrome style or textured style if you haven’t applied any material.
@JuvenileNayem, it strikes me to see so many icons of extentions while you seem to lack the knowledge of how basic tools work in SketchUp. Try to learn SketchUp first before loading/applying these extentions.
To address your question, either:
-
- use a section plane to section your building to be able to see where you want to place the door.
-
- use the ‘Position Camera’ tool to exactly place the camera opposite to the doorway to see where to place the door. (save this view in a scene)
(preferably option 1)
To build on GH Hubers post,
To help achieve your goals, some time spent at the SketchUp Campus and at the SketchUp - YouTube channel will be very worthwhile. Both sites are from the SketchUp team. On the YouTube channel, pay attention to the Square One Series and Level UP series. They cover the basics for each tool.
All icons is from one extension - V-ray
(Corrected my post above.)
One would think that you need a good model before starting to use rendering applications.
V-ray may be forgiving for back faces. But it’s still poor modeling.

But it’s still poor modeling.
Vray can only model a few primitives as lights: rectangle, oval, sphere… nothing else. The rest during rendering, such as grass, geometry modification…
