Generating tool path with raft enabled does not create raft on layer 1

[wnypokertinkercad]

Hi all.

I have a model that needs supports and also needs a raft for the 1st few layers for adhesion as the print is tall and narrow.   So I enabled the raft in the print settings editor.

As you can see from the images Fusion doesn't create the raft at the first layer but on top of a layer of support lines and then it lays down a raft.  The issue is because the raft isn't laying directly on the bed, it promptly curls up after a few more layers.    How do I make Fusion put the raft on the 1st layer?  Thanks.

Hi @wnypokertinkercad ,

What you're seeing is actually the correct behaviour for the default settings for the raft. That layer looks the way it is since the "Zigzag raft base" check box is enabled. Try disabling this option and you should get the behaviour you are expecting. 

It is not clear to users how some of these settings interact, so we will work to clean up the raft settings and make it more clear which settings are affected by the "zigzag raft base" setting.
