This is because QEPCAD is an experimental package, see this page. So you will have to install it first. The way to install it is to type, from a terminal:

```
sage -i qepcad
```

Note that since qemcad is an experimental, and looking at trac tickets 16642 and 10224, it is very unlikely that you will succeed to install it.

**EDIT** I am happy to say that qepcad has been repackaged so that 10224 is fixed and you should be able to install it now.
