I want to subtract the pyramids from the sphere. I made the pyramids into a group and tried to subtract the group from the sphere but sketchup says I need two solids. TWO SOLIDS ONLY.
how/where do i upload the model? BTW, I can start w a bunch of pyramids and start subtracting them one by one from the sphere ok. But if I try and save my work, sketchup complains that there is a problem and it wants to fix it. If I fix the problem, save , quit, and reopen then it will not allow me to continue my work-rather it gives me the error dialog pictured in the second image above.
Thank you colin. Yes I tried to make the sphere with windows cut out of it. This is an attempt at reverse projective geometry. A grid on a plane projected into the center of a sphere. I tried to reproduce what you did. Here is a pic:
On the left is the assembly of pyramids I want to subtract from the sphere.
The next three images show the construction of the hollow sphere. Basically I create an annulus first. Then I create a circle orthogonal to it. Then I click on the circle, click follow me tool, and then click on the annulus to get the hollow sphere.
Finally I move the sphere into position but for the life of me cannot figure out how to subtract the pyramids from the sphere. I keep getting the ‘not a solid’ error dialog. Attached is the model I have. I downloaded your model and yes it is very close to what I am trying to achieve. Interestingly, when I move the viewpoint into the middle of your sphere, nothing is visible outside
I went back to the beginning and created a simple hollow sphere. I then subtract a few pyramids from it one by one. But then, I noticed my sphere wasnt hollow any more but each cavity made by a pyramid subtraction left walls in the channel. I then have to delete each individual wall-way too much work.
I did a screen recording that also shows how I did the pyramids using built in tools. You should watch the dimensions box, that’s where a lot of what I did goes on. When the sphere disappears it’s because I cut it, to paste in place later on. I used keyboard shortcuts quite a bit, one of which is a custom one. I have ctrl-shift-z to Zoom Selection, it’s very handy. All done using my MacBook Pro trackpad.
For the moment going to YouTube will show better quality. I expect it will look better here later on.
