    I’ve been having some issues when using the Zoom Extents function in Civil 3D recently, it keeps zooming further than I expect to also encompass the origin point (see fig. 1 below).

    It had been bugging me for a while but was one of those things that you just get on with as my calculations and model were still correct. After a little jiggery-pokery I’m happy to report that I have identified the culprit of the issue, hopefully this will stop your computer needing to grow wings any time soon!

    It turned out it is related to the Marker Display of the GeoLocation feature. If Geographic Location Marker Visibility is set to ON when a profile is inserted Zoom Extents will also encompass the origin point. Simply setting the Geographic Location Marker Visibility to off having inserted the profile unfortunately will not suffice in resolving the situation. Instead you need to remove the profile from the drawing, set the Geographic Location Marker Visibility to OFF and then re-insert your profile. If you try the Zoom Extents function having done the above it should now be behaving as expected (see fig. 2 below). Happy days!
