For my work I have 3D obj models of coral reefs made in Agisoft and I use the PolylineOnMesh tool to cut out individual corals. This used to work well a year ago (https://1drv.ms/v/s!AvOC3oq4Zscw3ki6MpSU2rBKYfF0) but since this fall we are having troubles. In many of the models when I trace the coral around with the PolylineOnMesh and then click on the beginning point to connect the line to a circle, the line disappears completely (https://1drv.ms/v/s!AvOC3oq4Zscw3kf1yFi15CQZ38u-). Can someone help me figure out how I can get this to work again?
Curves are set to show and the polyline doesnt show up if I hide the mesh.
Sometimes a line doesnt work and the next time I try it does. Simple lines with a few nodes generally work but with more complex ones (many nods) it doesnt always work.
When I make lines that arent supposed to close I have the same problem.
