hi @Anonymous
Sorry about that! Didn't mean to miss the second part of your question 🙂
There's a couple different tools that we can use in combination to achieve this:
- Maya Distance tool - measure the distance between two points. Use this to verify the specific distance between parts.
- Insert Edge Loop Tool - insert an edge loop that is dependent on the poly flow of the object
- Legacy Split Polygon tool - this is the original version of the Multicut Tool. Some find it easier to use 🙂 To activate it in Maya 2018, use these steps:
- Type "SplitPolygonTool;" in your Mel Script Editor, and press enter
- When it populates in the upper window, highlight it, click and hold on it with your middle mouse button, then drag it up to your shelf to create a button
- Select MEL when the button prompt appears

Using these tools along with the ones in my original post, you should be able to mark the spots where you need your edge loops to be. The last strategy I would recommend using is the Snapping tool. Say you have one vert placed in the spot that matches your design, and you would like to match it's corresponding vert on the opposite side of the face:
- Select the vert you want to move/align (best to do this in an orthographic view - front/side/top/etc)
- Hold down V to activate the "snap to vertices" tool
- Move the selected vert along the appropriate axis - it will snap to the location
- If it snaps to the wrong vert, continue holding down V to adjust it.
- Use the Distance Tool to confirm that it is in the correct location
You can do a similar operation for edges as well 🙂
Do these tools sound like they will do the trick for your project? Any other questions I can help with?
