I would submit a bug report on that

Try to upload your file it will make it easier to help you, if its over 14 meg compress it.

Compress it or zip, it does not seem to be a big file. or another thing to try i find furniture can make a large file, so save as then delete things that are making it a large file Also show chief version

Try these settings

In camera view Cad Menu Automatic Dimensions Auto Story Pole dimensions or in section view draw manual dimensions

If this model interests you let me know i will upload it i don't get to use chief much now so i like to keep my skill practice going it may give you some clues

If you want I could do a screen share to help with that model if you want that send me a private message

I had play with your model its rough but the basic shape is there you will need to get it more accurate, hopefully you can continue from that, as for the terrain i got rid of over lapping height data see if you can follow on from there to get it better. I made your terrian data standout it helps when trouble shooting terrain problems you should be able to see any overlapping height data issues. Fox.zip

I would ask chief support they should be able to get you sorted with this question its about time they put out a video showing how these formulas work

This does not relate to your question but these new features shown in this video I think would be very useful to the type of work you do

You can turn it off in preferences also it ask when you install if you want to use it

Watch this video Railing Walls - Video | Chief Architect asuming your are still not using x8 if you are in x16 update your signature in the forum

I would report this to chief it seems like a bug to me

Transform replicate tool most items have that tool in there tool bar and z is up and down in 3d space check it out it can be a precise way to move things

Ask for dwg format, 3d only allows for a symbol and you cannot edit it.
