I have the feeling, that I do a simple step very complicated.
So I ask myself: Whats the fastest way to trim a closed solid with a surface and have the surface automatically fill the open part of the trimmed object?
Here a screenshot for better understanding:
This is my workflow:
Select Surface>Trim>click upper part of cylinder>enter>select trimmed cylinder>Trim>select surface outer part>enter>select both>join>enter
I have the feeling that there’s a faster way of doing that.
Even though the trimming surface isn’t a solid, because it passes all the way through the cylinder you can use it as one. To control whether you keep the top or bottom part you can flip the surface before the intersection.
Yes that is the slow way of using the Trim and Join commands.
Lots of unnecessary steps.
The fast way:
window select all objects> Trim> click on all parts to remove> ! Join
Notice you can immediately go from removing the parts you want removed to Join command - No need for an Enter after you’re done trimming if your Join button (or alias) has the exclamation mark in front of Join. .
① Only the surface is selected as the cutting object. The pipes won’t trim the surface. ② All objects are selected as cutting objects. The surface and pipes can trim each other.
Yep, that’s the best and fastest solution in my opinion.
It’s even easier if you go to Settings > View > Display Modes > Shaded and you set Backface settings to “Single color for all backfaces” and you set a different color in “Single backface color”. I generally use Brown. It works great to always visually see which is the backface of your surfaces.
In your situation, to correctly use the Boolean difference command, you’ll need the backface facing upwards.
