I am a newbie just starting to use SketchUp. Following along with this tutorial I have also encountered the same problem as jvh with Step 6. I right click on my imported plan, then click on "use as material". However, when I do this, the plan is NOT greyed out. Then when I click on the paint bucket and get the materials window, my plan is not in it, so I can't select and drop it in my square. I have tried using both .tif and .jpeg images but it doesn't seem to make any difference which format I import the image in. Can someone please tell me what I am doing wrong?
