Master the art of using crossing windows in geometry through this informative article. Learn how to erase unnecessary lines and apply fillets to create precise designs with ease.
Key Insights
- The article provides a step-by-step guide on how to use crossing windows for erasing unnecessary geometry. With the right technique, you can complete the task using only three crossing windows.
- Proper use of the eraser tool and understanding of the crossing window concept, which moves from right to left, are crucial. Precision is essential, and the crosshairs tool can help in lining up the crossing windows accurately.
- It also explains how to use the fillet tool to add rounded edges to your designs. It involves giving dimensions for the fillet and using the 'multiple' feature to add fillets to several corners simultaneously.

Now we can begin to erase some of this unnecessary geometry. And I would like to practice using crossing windows for this example. We can erase all of the geometry that's necessary using only three crossing windows.
And watch while I do it. I'm going to zoom in. I'm going to go to my eraser tool.
And remember that crossing windows are from right to left. So I will go C, Enter to lock in a crossing window. Here to here.
C, Enter. Here to here. And one more time.
C, Enter. Here to here. Notice each time I made the crossing window, I made sure to use my crosshairs to line up where that crossing window was going to go.
And let's do that one more time together. Eraser tool. C, Enter.
I make sure my crosshairs are above my geometry and to the right of my geometry and click. And I will highlight the geometry I need without going too far into the semicircle. I will click.
C, Enter again. And this time I'll make sure my crosshairs are again above, but in between the semicircle and this line and click. And this last one's fairly simple.
I could also use fence. But C, Enter. Any rectangle moving from right to left inside this toilet area will work.
And click. Enter to say that I am done. Zoom extents.
Roll out. CTRL+S to save. Now there are a few more fillets we need to add to this toilet before it is complete.
We can see that the bottom of the toilet has a 2-inch radius and this point from these lines to this horizontal line also has a 2-inch fillet. We can use fillet multiple and make sure we add 2-inch fillets to all four corners. I'll go to fillet.
R, Enter. 2, Enter. And then M, Enter for multiple.
I will choose here, here, here, and here. When I'm using multiple, I have to hit ENTER to say that I'm done. Now the only fillet we need left is to connect this line with this filleted arc.
And this line with this filleted arc. Now I need to erase these three objects. And in this case, I will use a fence.
Let's give this a shot. I will go to eraser. F, Enter for fence.
And I will start outside. Moving across. Click.
Down, click. And back up through, click. Now I can move my mouse away one more time just to show that I am done selecting my fence.
And hit ENTER to lock it in. And ENTER to erase those objects. You could also erase the objects by simply picking on them.
This final radius is a 10-inch fillet. So I will go to fillet. R, Enter.
10, Enter. And this time, I don't need to use multiple because I only have two fillets. So I will click here.
And click here. And then Enter to go back in. Here.
And here. I can go Zoom Extents. And CTRL+S to save.
In the next video, we will work on the range.
