Hi, Unfortunately, for the course that I am designing, the Lidar images are not available for half of the first hole. Even if I mask off that part of the course, as the course is on a slope, the resulting course file has a massive cliff half way along the first fairway that I have not been able to flatten in the designer. Can anyone think of any work arounds that will allow me to design the rest of the first hole?

Yeah you can flatten that, just use the brush and lower it a lot

I'm assuming that the opening tee shot is downhill IRL?
If there is no Lidar data for that part of the course, you're going to have to fill it in manually, you could use the Sculpt - Flatten brushes (RED) to raise up the tee / fairway, to where you guesstimate it is IRL, don't worry about placing the red brushes on the Lidar terrain, that's been generated with the Landscape (BLUE) brushes, so it won't be affected. Good luck !!

It could be a little oftopic but I've never used the sculpt brush (red). I don't know how it works, I tried but looks like it does nothing. I don't know. Can you write a brief explanation on how to use it? Thank you so much.

This thread pretty much covers it all:
Lidar courses are different, before you use any blue brushes on the outer plot, you can sculpt with the red brushes without affecting the Lidar terrain (the masked area / course)....pics might be able to "explain it" better.
Before...numerous different Lidar holes, combined on a single plot:
After...same plot with the outer terrain worked with the Red Flatten brushes:

Yes it is a downhill tee. The course is Cuckfield Golf Course Staplefield Road Cuckfield, West Sussex RH17 5HY United Kingdom

I can't find any "point cloud" Lidar at all for the course (it's the only Lidar I know how to use), and even all the different types of composite Lidar data, don't cover the part of the course that you are missing...to the best of my (limited) knowledge.

Yes that is right, there is no point cloud but there are DTM and DSM tiles. I have converted the DTM tiles into Lidar using LAStools. First I ran a program las2las to convert the ascii files to las. Then ran lasground to identify bare earth. Then ran lasclassify to classify the data. I ran it as a batch file as follows and ended up with some good Lidar file. Just missing half of the first hole:(
for %%f in (*.asc) do ( echo %%~nf las2las -i %%~nf.asc -o %%~nf_A.las lasground -i %%~nf_A.las -o %%~nf_B.las lasclassify -i %%~nf_B.las -o %%~nf.las del %%~nf_A.las del %%~nf_B.las )
