LEARN 3D #01 HOW TO BEVEL - SIMPLE COUCH a simple to understand example of how the beveling tool works when giving the finishing touches to your model. In this case the front row of couches shows the extra beveled models in "brown textured, shaded and wire-frame" modes. The back row shows how subdivision smoothing rounds the boxes of the couch. The couch in the middle is the original (non smoothed). And a wire-frame view of the original couch. HOW IT WORKS: In this case I selected all lines in a model (try the lasso tool on line selection) and added a small amount of beveling (0.5 ~ 1.0). Beveling is added to the current selection. The smoothing radius is now calculated between narrow added lines (segments) and makes a sharper appearance when smoothing is switched on. NOTICE: have a clean design, do not add too many lines or segments, it will be much easier to select and handle a low poly model. Beveling is your friend :) you will use it a lot. "Un-beveling" is a little more tricky and there are more techniques how to do it ... (weld, slide, delete). Note that un-beveling is time consuming and the results may vary. If you do not like the confirmed amount of beveling use "undo" (ctrl+z) to go a few steps back.
