Sometimes they are included in the main catalogue, and others they have their own catalogues. Try clicking the buttons on the lower of the two button bars above the window and see what you have.

It depends on the style.

Excellent!

Thank you. I will look forward to seeing your maps :)

Someone on FB was interested in the fact that the drain connecting symbol could wind back on itself. Not sure how practical that is, but I added a second drain sheet and put a glow on it to cast a shadow on the drain below.

I've also made a connecting wall with a matching floor fill, and added in a few symbols.

Hi Kevin :)

The best way to start is to absorb the information in the User Manual and work through the practical mapping exercise it contains. That establishes the basic uses of the software and should be enough for you to grasp the 'how to' of most things.

Then there are a huge number of video tutorials you can access here:

Also remember that if you get stuck and don't want to spend days trying to find just exactly the right bit of the right video, you can ask a question right here on the forum.

You could try selecting by layer?

Pick the delete tool and right click in the window, then pick Layer. You will be prompted for the name of the layer in the command line. Once you have entered the layer name on your keyboard you should then see in the command line how many entities are on that layer.

Best to check what they are before you go ahead and delete them, though.
