Simple free mechanical drawing package?

Hi,
I have to occasionally call for simple modifications to enclosures containing circuit boards.
EG add a cut-out, or a hole for cable entry, etc etc.
Eg, I need to be able to draw the enclosure, even if only in 2D, then send this drawing off to a metal basher so they can make it.
We cant afford Solidworks.
Do you know of any free, simple drawing package for this purpose?
 

I'm not sure how well this works for you in the UK but this is my goto for simple stuff. I've used it for a handful of professional and personal projects:
https://www.emachineshop.com/homepa...68_eQg.2&utm_referrer=https://www.google.com/

The pro and the con is that its tied to their machine shop. The benefit is that pricing is instant and it tells you if you've made something they can't build.


If I recall they'll convert it to a standard format but for a fee.

Two programs you can evaluate for your need.

1)Freecad- https://www.freecadweb.org/
-alternative to Catia or Solidworks in simple form

2)LibreCAD-https://librecad.org/
-autocad dxf format compatible and many formats for export
(pdf, bitmaps...)

From what you said, there is not only one 3D format that you have to work with, and considering that the purpose is only to generate the 2D projections, it could be the case to consider exporting their side/front/top views into any widely used format, such as DWG/DXF for example, which are supported by many CAD tools.
