I have imported from revit a model and I have several walls that are all diferent elemnts.
¿
How can I select all faces at the same time and colour them (inside, outside) by not having to go deep selecting every wall one by one?
What version of SketchUp are you using? You posted in the SketchUp Pro category but your profile says you are using SketchUp Free (web).
If you are using Pro, using Materials Tools to remove all materials from the model. Then apply the color to the components/groups in the model and then use Materials Tools to put the "Instance materials on the faces.
If you are using SketchUp Pro please correct your profile. That information helps us help you.
hello, if you just want to turn your walls to white, you can edit the green material.
press alt while using the bucket tool to load it in the material panel, go to edit tab and change color value with the picker you want
useful tip:
As @DaveR mentioned, deleting the revit material will apply the default material to all your model’s surfaces so you can paint it with a single click.
but:
have in mind that if you do that without opening the group, the material will be applied to front AND back faces which depending on your renderer might make it have double render times. It is worth the extra step to open the group and paint a single surface wile pressing shift.
If your group is comprised of other nested groups you might want to consider Fredo6’s ‘thrupaint’ plugin which can do exactly what you ask (without painting back faces).
Triple click will allow you to paint all the outer faces in one go.
Use Curic Deep Select plugin to select all the faces even if they are in different groups, and then choose the colors for the outer and inner faces, respectively.
Or you can use Paul’s solution, just change the color in Edit tab
