Another free plugin! I really can’t call it new because this one’s been a popular download for years, but it is still free. It does one simple function: it draws straight lines constrained to isometric angles (unless you hold down the shift key for 45-degree constraints or Option/Alt for no constraints), but this time, however, it’s a bit better. It borrows some functions from the Concatenate plugin so new lines are automatically joined if they’re drawn from the endpoint of another.
You probably already know that isometric drawings are easier when you turn on Smart Guides with the 60-degree preset and construction guides checked. Combine this with the free Isometric Actions and isometric clipart, and that was pretty much my toolkit for technical and assembly drawings until I discovered CADtools. Isometric Line Tool, however, is still one of my main tools. I gave it the keyboard shortcut “Y” (naturally) and use it often for simple tasks.
Please feel free to download and try the Isometric Line Tool. I hope it serves you long and well!
