Creating the final volume

Now we have a volume of the T junction, and we want to create another volume with the rest of the piece, connected to the first volume. Two volumes are connected if they share some surface. we will reuse the ring surface of the first volume for the new volume.

• Set off the layers "part1" and "union"
• Send the shared surface to the "part1" layer, to facilitate the selection of the new volume boundary: select "part1", use Send to->Surfaces and select the surface of the image and press Escape

• Set off the layers "pipe1" and "pipe2" and set on "part1" and "union", and send "part1" as layer to use, to create the new volume in this layer.
• Choose Geometry->Create->Volume->By contour and select all the visible surfaces to define the volume. Press ESC to conclude the selection process.
• Choose Render->Smooth to visualize a more realistic version of the full model with all layers on.
