Can you easily make an edge loop go through a triangle? Is there any way to do something similar to Maya's insert edge loop tool, where the edge loop wraps around the triangle? (Using Ctrl + R makes the edge loop stop before the triangle)
In wireframe mode you can select easily all the edges what you want to cut at once.
To create the new loop on them select Edge&gt;&gt;Subdivide.
Now you can adjust the number of cuts on the bottom-left.
If you want to move them, select a loop and double hit &quot;G&quot;.
To create more loops after the move, select a loop and choose
Edge&gt;&gt;Bevel Edges.
