Sigh, that’s messed up!
It would be simpler to create a 50′ grid from random topo points, and when you go to the field to stake them take a shovel and gently adjust the ground to make the calced elevation match the ground one.
But, if you really have to do it this way; create two points along a long line extending well beyond the site. Stake a line between them in stakeout, hit each 50′ station and collect a point, keep staking that line and do the same thing at each 50′ offset. It’s easy in access and I’ve done it many times for real reasons, not for topo, but heck might as well use it, it’s fast, simple, quick and your grid is finished.
In C3D, make a dummy surface with the polygon at 100-foot elevation, then use the Create Grid of Points command.
That command forces you to make a rectangular grid, so there will be points outside the polygon, but you can just use Quick Select to grab and delete all the points that are outside of it (not at 100 elevation).
“…people will come to love their oppression, to adore the technologies that undo their capacities to think.” -Neil PostmanThank you. Thats one way i did it in TBC. Just gave the polyline an elevation made a surface and did a grid of points yes same some fall in and out. I like this method because i can do it bu sections or zones and have a way to manage point numbers that match the zones but that is irrelevant. I am going to try civil 3d as i have very limited experience with it this weekend. I have played and done it just about every way suggested and figured out the time difference in TBC only so far and point count. Still makes no since that one cant just do it straight from a polygon elevation not needed. Thanks now off for a road trip as daughter at FFA event and some transportation issues arose. Lol
I agree but we have not done the topo and they have to be computed before the topo so we know where to topo. Lol. Yeah i know. Silly.
So another gis function would be once i create a grid of points and some fall outside the polygon being able to remove those vs selecting and deleting. Or run a buffer of the outside tolerance and hold everything in that and inside polygon and remove everything else. So great functionality that should be added to surveying software for sure. Lots of little time saving tricks in that stuff.
