I want to create planar surfaces for all 6 sides of 3D bounding box sketch. But contour selection tool doesn`t give me ability to select some side contours.
The Planar Surface command can't use 3D sketches- even if they're technically on a 2D plane.
The way that I would make this part is to make the box as a solid from a 2D sketch, and then do a surface knit on all of the sides (without selecting the "create solid" option). No need to use 3D sketches for a simple shape like this.
You are wrong a little bit, I can create planar surfaces for top and bottom sides
But can`t for others because of opened contour.
Note: I need 3D sketch as skeleton for weldment - it`ll be wooden box, sides are made from plywood which are connected by bars at corners.
Yes, contour select seems to have limitations for Planar entity/selection sets per feature?,.. here would be for boundaries form within a single 3DSketch seems to be limited what it determines is a closed boundary.. so, you need to make a new Planar feature?
I don't understand the "rule" but it may have something do with the boundary(contour) they form within/during a single 3DSketch creation?... that is, if make (12) "individual" 3Dsketches .. there is NO option for a contour but...
Fill Surface.. I was WRONG about for Contour selection,.. it seems you can make multiple entity selections!... is/was this NEW for 2018?...(since I typically use 2014).
If I don`t want to select contour I switch on edge filter and select edges or use box select.

Have you thought of extruding a solid and using the Convert Entities tool in a 3d sketch, then delete the body? It's a technique I learned from Alin Vargatu at SW World a few years ago. It creates a few more features in the tree, but it's much simpler to control the 3d sketch that way. I believe it's faster overall.
Igor.. yeah, negative for Planar.. so, the next logical would be Fill.. but another negative because we don't have a SelectionManager option????.... so,... the next would be,.. Boundary/Loft.
Thanks Paul, I use surfaces rarely, so I`ll try
I`ve done this
Planar surface feature accepts two or more edges, so it is possible by box select to create sides with ease!
Unfortunately this way doesn`t work for tetrahedron (:
Thanks, Paul, loft works in this tetrahedron case
