How to build a sofa model in 3D MAX can make the sofa press lines instead of mapping.

Use "Tian" as a metaphor for the sofa, and the cross in the middle indicates the pressing line. First select the middle vertical line (alt+l cycle selection). Then cut the corner, one line becomes two, and the cutting angle should not be too big, that is, the line trench. Build another line between the two lines (you can choose a line segment between the two lines, select the alt+r ring first, and then connect them. Use the zoom tool to reduce the new line, just a little. Oh, this is the depth of the groove, and finally add a smoothness to the whole. There are several basic smoothing methods. The feeling of pressing the line came out,

The needle and thread on the sofa can only be mapped, so no one should be stupid enough to build that thing. .
