Understanding Your SketchUp Pro 2020 Classic License: A Complete Guide
If you are still running SketchUp Pro 2020, you are likely one of the few users holding onto a Classic (Perpetual) License. Unlike today’s subscription-based model, these licenses were purchased once and lived forever on your machine. However, managing them can be tricky since Trimble discontinued the sale of new Classic licenses in November 2020.
Here is everything you need to know about locating and authorizing your 2020 Classic license key and authorization number. 1. Where to Find Your License Information
Your Classic license details—specifically the Serial Number and Authorization Code—were sent to the email address used during the original purchase.
Email Search: Look for a verification email from "SketchUp" or "Trimble" containing your unique codes.
License Manager: If you still have the software installed, you can find the Serial Number by selecting Help > License (Windows) or SketchUp > License (Mac).
Online Retrieval: You can attempt to retrieve lost codes through the official SketchUp License Retrieval tool. 2. How to Authorize SketchUp Pro 2020
To activate your software using these codes, follow these steps:
Launch SketchUp 2020. If you don't have it, ensure you download the correct 2020 version, as newer versions will not accept these codes.
Open the Licensing Window: Click Add License in the "Welcome to SketchUp" dialog. If it doesn't appear, go to Help > License. Enter Your Details:
Copy and paste your Serial Number (typically starts with "V" for the 2020 version).
Enter your Authorization Code exactly as it appears in your email.
Confirm: Click Add License. Once authorized, the software should no longer prompt you for sign-in or trial information. 3. Key Differences: Classic vs. Subscription

If you've lost track of these numbers, here is the path to find them:
The Digital Paper Trail: Search your inbox for an email from sketchupmail@sketchup.com. This was sent immediately after your purchase and contains both keys.
The License Manager: If the email is gone, use the SketchUp License Manager. You’ll need the email address used for the original purchase to look them up.
Inside the App: If you still have SketchUp 2020 installed on an old machine, go to Help > License (Windows) or SketchUp > License (Mac) to view your active serial number.

SketchUp Pricing 2026: Go, Pro, Studio & iPad Plans Compared
For SketchUp Pro 2020, a standout feature for many users was the automatic transparency of obscured objects when using Move or Rotate tools. This drastically simplified positioning items in tight or cluttered spaces by making an object transparent the moment it encountered an obstruction.
Below are the key features introduced in the 2020 release, which was notably the final version to support the Classic (Perpetual) License before Trimble transitioned to a subscription-only model. Top SketchUp Pro 2020 Features
Outliner & Model Organization: The Outliner was overhauled to increase performance. You can now manage and organize your model directly within the Outliner using an "eye" icon to toggle visibility, reducing the need for excessive layers.
Bounding Box Grips: Objects now feature grips at corners, midpoints, and centers. When moving an obscured point (like a back corner), the object automatically becomes transparent if it's blocked by other geometry, allowing for precise placement.
Decoupled Hidden Geometry & Objects: Hiding objects is now separate from hiding geometry. This allows you to hide distracting nearby objects (like trees or buildings) while still being able to edit the hidden edges of a landscape or smoothed surface.
Terminology Change (Tags): In this version, "Layers" were officially renamed to "Tags" to align more with industry standard terminology, though their core function remained similar.
LayOut Model Control: LayOut 2020 introduced better document control, allowing you to change styles or camera angles directly in LayOut without losing those changes when the main SketchUp model updates.
Weld Edges (2020.2 Update): A native Weld Edges tool was added, allowing you to combine individual edges into a single curve without needing a third-party extension. Managing Your Classic License WHAT'S NEW In SketchUp 2020.2?
