Sorry I still have that version of Sketchup. Ok let me tell you what I’m trying to achieve.
I’m currently importing a Point Cloud file that represent a building.
I’m going into the Camera → Standard View - > Left
I’m going into Point Cloud Tool Box and selecting Create clipping box from point cloud to create a slice of my building from left to right that contains all the building but just keep couple inch height for my slice.
Back to Camera ->Standard View → Top, now I have only the exterior walls of my building.
Use the Lines tool to draw exterior perimeters of the building. Since the building is not straight, I need multiple lines to create the exterior perimeters of the building.
Now I want to use the Offset tool to create a double boundaries of the exterior perimeters, that would represent the exterior walls tickness.
When I click on the offset tools, I got the message: You must select a single face of an object or…"
I realized its maybe because some of the line are not connect together. So I taught there is a Join fonction in the pro version of Sketchup that will connect 2 lines together and after I will be able to use the Offset tools but I tried different methods and it doesn’t work.
Do you have an idea how to connect multiple lines together (that are not in youtube tutorial) or I should use a different method?
Your lines must not be in the same plane, or something else is amiss with the geometry you created. Did you lock your lines to a plane when you created them? Being in one of the standard views does not lock tools to a specific plane.
Weld is what you are looking for, but in order for offset to work you need to have everything in a plane. And weld will make all your corners smooth when you Push Pull. It doesn’t magically join lines that are not connected, but it can help.
You could make a component of your lines, use Eneroth Flatten to Plane Plugin, make sure the face is closed, then offset.
Or better still - draw a large rectangle positioned where you want to create the offset lines, make it a group, and while editing this trace your shape, or better still right click on the surface of the rectangle and Intersect faces with model.
You could then use the interesteded geometry to create your offset lines.
