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?

SketchUp Pro 2020: Understanding Classic License Keys and Authorization Numbers
For many long-time 3D modelers, SketchUp Pro 2020 holds a special place in their workflow. It was the final version of the software to fully support the "Classic" perpetual license before Trimble transitioned exclusively to a subscription-based model.
If you are trying to reinstall this specific version or move it to a new machine, understanding how the Classic license key and authorization number work is essential. What is a SketchUp Classic License?
Unlike the current "Sign In" method used for SketchUp subscriptions, a Classic license is a serial number and authorization code pair.
Serial Number: Usually begins with a letter (e.g., "U" for 2020).
Authorization Number: A unique alphanumeric string provided at the time of purchase. How to Find Your SketchUp 2020 License Details
If you’ve lost your credentials, there are three primary ways to recover them:
Check Your Confirmation Email: Search your inbox for "SketchUp License" or "SketchUp Pro 2020 Order." This email contains both your serial number and authorization code.
The License Manager: If SketchUp 2020 is still installed on an old computer, go to Help > License (Windows) or SketchUp > License (Mac). You can view your serial number there, though the authorization number may be partially masked.

A Classic license typically allows for two active installations (e.g., a desktop and a laptop). If you get a "Too many activations" error, you must Remove License from one of your old machines while connected to the internet to "free up" the seat for your new computer. The Shift to Subscription
Trimble officially stopped selling Classic licenses in late 2020. If you are looking for a new license key today, you likely won't find one through official channels. Beware of websites claiming to sell "cracked" license keys or "keygens"—these are often fraudulent and pose significant security risks to your hardware. Support for SketchUp 2020
It is important to note that SketchUp 2020 has reached its "End of Support" phase. This means it no longer receives security updates, and web-based features like the 3D Warehouse or Add Location may no longer function within the 2020 interface.
For users who rely heavily on these cloud features, upgrading to the latest subscription version is generally recommended. However, for those who simply need a stable, offline 3D modeling tool, the 2020 Classic license remains a powerful asset.
