I was fairly competent on Sketchup, but it’s been awhile.
I’m using Sketchup Make 2017 on a Windows 10 system to model Jefferson’s stacking book boxes as published in Popular Woodworking’s June 2011 issue. Although the 3D Warehouse has PWW’s staff model, I wanted to do it from scratch for practice.
After completing the first pass on the top box’s model, I arranged the components by layer and scene and went on to model the middle box. As the joinery was similar, I copied the upper box out the X axis, exploded a new instance of each of the copied components in turn and created a new component for the middle box, created layers and assigned each new component to a new layer; I then created new scenes to control what was on the screen. That’s where my problem came up.
If I turned off the layers for the copied over/exploded/new components for the middle box, I got what I expected so long as the upper box’s components were also selected: de-selecting the layer for the middle box turned off the associated components. But de-selecting the layers for the upper box (the original that was copied over) turned off both the component in the upper box and the matching components in the middle box. I verified that each component was in its appropriate layer, and even deleted all the new scenes and recreated them. It still didn’t work.
So I started over. I went through the same steps but this time everything worked properly. Thinking that I was good to go, I then copied the middle box over as the starting point for the bottom box and proceeded using the same steps. (Although the steps were straight forward, I didn’t document them, so I cannot state that my steps were exactly the same.) This time the original problem came back: using the layers to turn off the elements in the bottom box worked properly, but, de-selecting the layers in the middle box also turned off the matching bottom box layers even though they were still selected as “on” in the layers tray.
That 2nd attempt is linked below:
I would sincerely appreciate any suggestion on what the problem might be.
