Can't construct sloped paths?

[KClarkSC2]

I can't seem to construct sloped paths of any sort. The controls for this are greyed out and unclickable. I hope I'm just overlooking something extremely simple...

You are, indeed. You need to select bridge mode (the button in the bottom right of the window), then click a tile or an existing path piece to start building.

Thank you so much, I had clicked the bridge mode but hadn't remembered that you need to click on an existing path first to get started. Been a few years since I've played...
