It has a number of different functions in terms of how it edits a mesh, but the basic one is to simply cut a <i>&#8216;ring&#8217;<\/i> or &#8216;<i>loop<\/i>&#8216; around the mesh in a particular direction.<\/p>\n<blockquote><p><b>Design note<\/b>: A &#8216;loop&#8217; is basically a cross-section of an object. Or if you think about it as someone taking a black marker pen and drawing a line around your midriff, that would be a single &#8216;loop&#8217; which &#8216;cuts&#8217; around your body following your contours, dips and general shape. A &#8216;Loop Cut&#8217; on a mesh is essentially the same.<\/p><\/blockquote>\n<p>With the object in Edit mode (&#8220;<b>TAB<\/b>&#8220;) move the mouse cursor near the mesh and press <b>Ctrl+R<\/b>, a pink line will appear and wrap around the model &#8211; this is a guide telling you where the cut will be made.<\/p>\n<blockquote><p><b>Design note<\/b>: If you move the mouse over the mesh the pink line will change position relative to the edge nearest the mouse, each time it does this it&#8217;s telling you the cut would be made along that orientation\/edge.<\/p><\/blockquote>\n<div class=\"content_images\">\n<p><a href=\"https:\/\/www.katsbits.com\/images\/tutorials\/blender-basics-using-for-first-time\/blender-basics-loop-cut-tool.jpg\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" title=\"Crtl+R to create a loop cut\" src=\"https:\/\/www.katsbits.com\/images\/tutorials\/blender-basics-using-for-first-time\/blender-basics-loop-cut-tool_sml.jpg\" alt=\"Crtl+R to create a loop cut\" width=\"640\" height=\"478\" border=\"0\" \/><\/a><\/p>\n<p>After pressing &#8220;<b>Ctrl+R<\/b>&#8220;, the pink line that appears indicates the direction the loop will be cut along the mesh<\/p>\n<\/div>\n<p>To &#8216;set&#8217; the cut in a particular direction <b>LMB<\/b> click. The line will turn yellow indicating to you that the cut is going to be made in the direction of the new line. Hold the &#8220;<b>Ctrl<\/b>&#8221; key down as you move the mouse, the loop cut line indicator will now &#8216;snap&#8217; to regular intervals as it moves &#8211; it&#8217;s snapped to the grid &#8211; making it easier to add cuts at regular measured intervals in the mesh.<\/p>\n<p>So with Ctrl held go ahead and move the indicator to the centre of the object &#8211; if you look at the bottom left of the 3D work zone you&#8217;ll notice some numbers to aid in doing this, when it reads &#8220;<b>0.000<\/b>&#8221; click <b>LMB<\/b>. This will then &#8216;set&#8217; the cut in place and we can move on. If you haven&#8217;t already, go ahead and add two cuts similar to those shown in the image below, both are down the respective centre-line of each particular direction. The chair is basically made from a series of these cuts.<\/p>\n<blockquote><p><b>Design note<\/b>: <b>Ctrl+Z<\/b> is Blenders &#8220;<b>undo<\/b>&#8221; feature, use that if you make the cut in the wrong place. You can also &#8216;<b>sub-divide<\/b>&#8216; and edge to create a cut by selecting it (RMB+Shift to multi-select) via the two pink dots at either end and clicking the button titled &#8220;<b>Subdivide<\/b>&#8221; in the &#8220;<b>Mesh Tools<\/b>&#8221; panel in the tool bar area below.<\/p><\/blockquote>\n<div class=\"content_images\">\n<p><a href=\"https:\/\/www.katsbits.com\/images\/tutorials\/blender-basics-using-for-first-time\/blender-basics-loop-cutting.jpg\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" title=\"RMB clicking to 'set' and 'fix' the loop cut around the mesh\" src=\"https:\/\/www.katsbits.com\/images\/tutorials\/blender-basics-using-for-first-time\/blender-basics-loop-cutting_sml.jpg\" alt=\"RMB clicking to 'set' and 'fix' the loop cut around the mesh\" width=\"640\" height=\"478\" border=\"0\" \/><\/a><\/p>\n<p>Making a loop cut by RMB clicking to &#8216;set&#8217; where the cut should be made, then once again to &#8216;fix&#8217; the cut in place resulting in a new loop around the mesh<\/p>\n<\/div>\n<p><a id=\"moreloops\" name=\"moreloops\"><\/a><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Adding_more_loop_cuts_to_the_mesh\"><\/span>Adding more loop cuts to the mesh<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>What needs to be done next is a couple more cuts added to the mesh so we can then &#8216;extrude&#8217; various shapes out of it, namely the back and legs, to make the &#8216;chair&#8217; shape. So add some more loop cuts as described above; as you make each cut, <i>remember to hold the <b>Ctrl key<\/b> down<\/i> so the tool snaps to the grid as it moves. Also keep an eye on the numbers bottom left of the work zone &#8211; in this example the distance (which is what the numbers measure) was &#8220;<b>0.6000<\/b>&#8220;, so set each cut when that number is reached (don&#8217;t worry if you don&#8217;t get it right first time).
