I have created an enclosed volume with surfaces (using 3D sketch and Filled Surface command) and wondered if there is a way of turning that into a solid. I tried Thicken command but it is not what I was looking for.
Many, many ways to do this. One is to knit all your surfaces together and in the Knit Surface manager you'll get an option to 'Merge entities' and 'Try to form solid'.
There will now be a flood of responses to this - just wait ...
This worked perfectly. Thank you.
if your volume is "water tight" then you should be able to use the "Create solid from enclosed volume" under the Thicken Feature.
I thought it was "water tight" but there was no option in Thicken command for "Create solid from enclosed volume". There were only Surface to Thicken and Thickness. I did it with the Knit Surface instead but Thicken was what my intuition called for. Thank you.
Personally I'd knit the surfaces and then use the thicken command. I know it's two separate features, but in a complicated model with a long tree it's easier to see when the surface becomes a solid IMHO.
You built your part with separate surfaces. Even though all of the edges touched properly to look water tight, the edges weren't actually connected. You needed to knit the surfaces together to make it water tight. If you roll back before your Knit feature and run the Check Part, it will show you all of the open edges. Those open edges are why it wouldn't thicken to make a solid. If you edit your Knit and uncheck "Attempt to make solid" and then run Check Part again, you will see that all of the open edges are gone.
