# 3D Inlays / Extreme Angles / Machinability

## Extreme Angles

![Handle Inlay](https://mintcdn.com/corbinsworkshop/K92D3dW8RfwAo7lv/images/handle-inlay.jpeg?fit=max\&auto=format\&n=K92D3dW8RfwAo7lv\&q=85\&s=9da74ef2c53dee3db4f75ba21b281ac6)

Steep Edge

Note some potential issues when you create a plug that approaches the vertical edge of a piece, as shown above. The curved inlay (Hibiscus Flower) on this handle is very close to the edge of the handle, and the handle isn’t very thick.

The resulting plug is shown below. It has two problems for machinability: the edges are past vertical and overhanging, which is impossible for a bit to machine. The curved edges are also too close to the edge of the inlay plug; another thing that a bit can’t get into.

Areas that require undercutting

Machining this shape will result in a plug that won't fully seat, and it will be gappy. (I know, because I accidentally did this!).

The easy fix: select the top planar edges (shown in blue) and do a ""Move", and move them down until they no longer would cause a problem.

The edges are first selected, then moved down a bit.

The modified plug

This creates a much more machiable plug.
