Struggling to input levels and Newbie

I trust someone can help

I have just downloaded the software a reviewed the tutorials and am starting to doubt if Kubla can do what i had hoped.

I would like to load a PDF of a construction site and manually input the existing point levels and contours and then the finished levels. I have no data sets or CAD to import.

The examples all seem to be based on uploading drawings that already have information on them that the software can read.

When i have tried to put levels in i am told i need to set the boundary.

When i do this i have to manually enter some levels, however after i have done that i am not able to put spot level in.

Can anyone please help me or point me in the right direction for a turorial

Thanks
