Did you get your answer Garrett?
It took me a decent amount of time (like an hour!!!) to find where the hell I could access the Laubwerk tool set from... then after randomly just clicking away searching, searching....success!!
Go to your Tool Set Palette
Click on the 3 horizontal bars that expands for additional menu options
Choose "Customise" - the last option on my list
takes you to the Workspace editor
My workspace name is Landmark ANZ (at the top) - because I'm in Australia - and click on the "Tool" radio button
You should have a long list tool sets below in alpha order.... go to L...and there's Laubwerk!!
Just expand the drop down arrow, choose the little icon and drag it into the other column - into whatever Tool Set your prefer... I dropped it into the Site Planning Tool, with the other planting tools. see screenshot attached.
Honestly, sometimes Vectorworks overlooks communicating the most fundamental parts of the "How to" meaning literally hours of wasted time and unnecessary frustration.
Now - I have to work out how to link the damn Laubwerk tool content to the Plant Tool, so all my database data is populated correctly.
for what it's worth.... I was expecting to be blown away by this new tool... have to say, I'm pretty underwhelmed. Very small selection of plants, barely a handful of Australian species and the only Eucalyptus included in the database is very poor indeed, and there's no way I'll be using that particular one with my clients (looks rather like a toilet brush). To be fair - I do have extremely high expectations. Glad I have my own database to fall back on.
