emulti  filed a deletion request for draftsight :
Draftsight 2D CAD software is not 'freeware' but a commercial software
sublicenced from the authors (Graebert Gmbh) by Dassault Systemes, and
provided on a free-of-charge commercial licence for a limited period,
which has now expired.
The Windows (and Mac) versions continue on a commercial paid basis,
but "support" for the Linux platform has now been withdrawn, no
licence is available.
Discussion of this package has recently centered around enabling
continued use of this software in breach of the licence terms. Links
have been provided to the installation rpm.
I suggest that continued publication of this package on AUR exposes
the Arch Linux project to legal risk for publishing/distributing
commercial software. You may wish to consider removal of this package.
