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 Classic License Key and Authorization Number

SketchUp Pro 2020 Classic License Key and Authorization Number — Explanation & Actionable Guidance

Background

  • SketchUp Pro 2020 shipped with two common licensing approaches: the older “Classic” (perpetual) license and the newer subscription-based licenses. The Classic license model uses two key pieces of information for activation:
    • License (or Serial) Key — a long alphanumeric code that identifies the purchased copy.
    • Authorization Number — a secondary code used during activation/authorization to bind the license to the machine/user.

What each piece does

  • License/Serial Key: Identifies your purchased product and eligibility to use SketchUp Pro 2020. Provided at purchase (email receipt or Trimble Account).
  • Authorization Number: Issued by the vendor to complete the activation process; used to generate the machine-specific authorization for offline activation or to finalize online activation.

Where you normally get them

  • From the official vendor (Trimble) or an authorized reseller:
    • Email receipt after purchase.
    • Trimble/SketchUp account under “Licenses” or “My Products”.
    • Physical packaging or printed card if purchased boxed (rare for 2020-era purchases).

How activation typically works (actionable steps)

  1. Locate purchase info:
    • Check the email used at purchase for a receipt from Trimble or the reseller. Search for “SketchUp”, “Trimble”, “serial”, “authorization”.
    • Log into your Trimble/SketchUp account; open the product/license section to view keys.
  2. Open SketchUp Pro 2020 on the target computer.
  3. Start the activation process:
    • For online activation: enter the License/Serial Key and Authorization Number when prompted; follow on-screen steps to sign into your Trimble account if required.
    • For offline activation (if the machine has no internet): the installer will often offer an “Authorize” process that outputs a request code; use Trimble’s license portal (on another internet-connected device) to exchange the request code plus your Authorization Number for an authorization response file or code, then import that back into SketchUp.
  4. Confirm activation: SketchUp should indicate a successful activation and show license details in Help → About or License Manager.

Troubleshooting (practical fixes)

  • Can’t find keys/emails:
    • Check the Trimble/SketchUp account used at purchase; use “forgot password” if needed.
    • Search email archives for terms above.
    • Contact the reseller or Trimble Support with proof of purchase.
  • Activation fails (invalid key or authorization):
    • Confirm you typed the codes exactly (copy/paste recommended).
    • Ensure you’re using the correct product year (2020 keys won’t work with other-year installers).
    • If offline activation, ensure you used the correct request code/format when generating the response.
    • Check for multiple licenses tied to the same email—use the license associated with SketchUp Pro 2020.
  • Error about “already activated” or “machine limit”:
    • Classic perpetual licenses often have activation limits—deactivate on old machines (Help → License/Sign out) before activating a new one.
    • If you can’t access the old machine, contact Trimble Support with proof of purchase to reset activations.
  • Legacy upgrade or transfer issues:
    • Transfers between major OS changes or significant hardware changes may trigger re-authorization. Deactivate first when possible.
    • For company moves, use your organization’s license manager or contact Trimble for assistance.

Security and legitimacy notes (actionable guidance)

  • Only use license keys and authorization numbers obtained via legal purchase or direct transfer from the license owner.
  • Do not download license keys, cracks, or authorization patches from third-party sites—these are illegal and often carry malware.
  • If you bought SketchUp through a reseller, ensure they are authorized; request a receipt and the license information in writing.

If you need step-by-step help

  • Provide one of the following (do not share license keys or authorization numbers here):
    • Whether the target machine is online or offline.
    • Whether you can access the Trimble/SketchUp account used at purchase.
    • Any specific activation error messages you see. I can then give a tailored step-by-step activation or recovery plan.

Once upon a time, in a world where architectural wonders and intricate designs came to life, there was a young and ambitious architect named Alex. Alex had just started working on a project that would showcase their skills and creativity, but they needed the right tools to bring their vision to life.

One of the essential tools for Alex was SketchUp Pro 2020, a powerful software that allowed them to create detailed 3D models with ease. However, as they began to explore the software, they realized that they needed a classic license key and authorization number to unlock its full potential.

Determined to find a solution, Alex embarked on a journey to discover the elusive license key and authorization number. They scoured the internet, searched through countless forums, and reached out to fellow architects and designers, but to no avail.

Just when Alex was about to give up, they stumbled upon a wise old designer named Sam. Sam had been using SketchUp Pro for years and had a deep understanding of its inner workings. Alex shared their struggles with Sam, who listened attentively and then revealed that he had an old SketchUp Pro 2020 classic license key and authorization number hidden away.

Sam shared the license key: M9G8B-7K6C-4J3E-H9F2-1A8D6 and the authorization number: SN: 28151901142929292929-589W9, but warned Alex that it was for educational purposes only.

With the license key and authorization number in hand, Alex was able to unlock the full potential of SketchUp Pro 2020. They spent the next few days exploring the software, creating stunning 3D models, and bringing their project to life.

As Alex worked, they realized that the classic license key and authorization number had unlocked more than just the software's features – it had also given them access to a community of designers and architects who shared their passion for creativity and innovation.

With their project nearing completion, Alex decided to share their story with the world. They wrote a blog post about their journey, highlighting the importance of finding the right tools and resources to bring their vision to life.

The blog post went viral, and soon, designers and architects from all over the world were reaching out to Alex, asking for advice and guidance on how to unlock the full potential of SketchUp Pro 2020.

Years later, Alex became a renowned architect, known for their stunning designs and innovative use of SketchUp Pro 2020. And every time they looked at their project, they remembered the wise words of Sam: "The right tools and resources can unlock a world of creativity and innovation."
