I'm having a problem importing .fbk files. When I import a .fbk file into a survey network I have Insert figure object and Insert survey points checked. The survey network coordinates match the .fbk file just fine. However, the drawing coordinates are shifted about 4 feet. I've checked to make sure the Survey database is set to US Survey Feet. There is no projection and no measurement corrections selected. Any ideas as whats going on would be greatly appreciated.

Here's my .fbk file:

A us survey foot is 1.000002.. times larger than an international foot. If you multiply your coordinates shown below by that factor the resulting location is about 4 feet away. Check your setting in the prospector. I bet it is set it feet and not us survey feet

I've checked that and verified that all settings are using US Survey feet, but I'll check again....

The survey itself has specific settings.

make sure haven't accidentally assigned your survey a coordinate zone. When a projection is assigned to a survey, the program will process scaling to your survey data when it gets inserted into the drawing.

Certainly if the drawing has no projection, it will think it is receiving International feet. BUT - if your survey database has a projection/zone assigned to it, the survey thinks it is in US Survey feet.

Hence, you will most certainly see a US Surveyfoot/International foot conversion occur at import.

Remember:
1 US Survey Foot = 1200/3937 m
1 International Foot = 0.3048 m
