For many 3D modeling enthusiasts, woodworkers, architects, and hobbyists, SketchUp Make 2017 holds a legendary status. It represents the final release of Trimble’s completely free, fully-featured desktop version of SketchUp that could be used offline for personal, non-commercial projects. Understanding how to download it correctly is crucial, as it is no longer available on the official SketchUp homepage. What is SketchUp Make 2017? SketchUp Make 2017 is the last iteration of the "Make" series—a freeware version intended for home use, educational purposes, and hobbyist projects. Unlike the modern web-based SketchUp Free (which requires a constant internet connection and runs in a browser), SketchUp Make 2017 is a standalone desktop application ( .exe for Windows, .dmg for Mac).
Search the help center for "Download SketchUp Make 2017" or navigate to their "Previous Versions" or "Archived Downloads" section. (A common working path historically has been: Support → SketchUp → Downloads → Older Versions).
Always download directly from help.sketchup.com and ensure you get version 17.3.116 (the final build). Avoid "cracked" or "portable" versions from torrent sites—they are often infected with malware and are illegal. If you cannot find the official legacy page, contact Trimble Support directly and request a download link for SketchUp Make 2017 (non-commercial).
Go to help.sketchup.com – the official Trimble support site.
You need the latest file formats, use a modern Mac (Catalina+), require professional rendering plugins, or collaborate with teams using SketchUp 2020 or newer.
This LMC simulator is based on the Little Man Computer (LMC) model of a computer, created by Dr. Stuart Madnick in 1965. LMC is generally used for educational purposes as it models a simple Von Neumann architecture computer which has all of the basic features of a modern computer. It is programmed using assembly code. You can find out more about this model on this wikipedia page.
You can read more about this LMC simulator on 101Computing.net.
Note that in the following table “xx” refers to a memory address (aka mailbox) in the RAM. The online LMC simulator has 100 different mailboxes in the RAM ranging from 00 to 99.
