This may be due to using a custom layout created in Cinema 4D 2023.1.3 (or older) before the new tools were added.
To better understand the issue, I should first clarify that the Cinema 4D preferences, where your custom layouts are stored, are not affected/updated/overwritten when you update Cinema 4D.
Keeping that in mind, when you update from Cinema 4D 2023.1.3 (or older) to Cinema 4D 2023.2.0, it will use the same preferences. This is only the case for incremental updates. Cinema 4D 2023 will not use the same preferences as Cinema 4D 2024 and newer or Cinema 4D S26 and older.
So, if you created a custom layout in Cinema 4D 2023.1.3 or older, the new Thicken and Symmetry Object will not be available since these new tools did not exist when you created the custom layout.
A simple test to verify this would be switching to the Standard layout and checking if the new tools are available.
If the new tools are available in the Standard layout, this confirms the custom layout is the cause of your issue.
Fortunately, you do have some options when it comes to adding the new tools to your custom layout so you do not have to rebuild the custom layout from scratch:
1. Open the commander by hitting Shift+C, search for Thicken, Symmetry, or whichever new tool is missing, drag n' drop the new tool onto the UI from the commander, and resave the layout.
2. Download the included pallet.l4d file located at the bottom of this page; right-click on your Cinema 4D UI, choose Load Palette..., and locate the pallet.l4d file you downloaded, and click Open.
Next, right-click on your Cinema 4D UI and choose Customize Palettes... This will open the Command Manager in edit mode. Once in edit mode, you can drag n drop the palette icon onto your UI and save the layout. Once complete, close the command manager to turn off edit mode.
Bonus tip - you can remove the old pallet that does not include the new tools by double-clicking on the icon while in edit mode.
