I do the following: 1) Use Construct to make a 3D regular field. 2) Add 10 to the z component with Mark->Compute(a)=[a.x,a.y,a.z+10]->Unmark
Now if I use Inquire(is regular positions), I find that the field is no longer regular. Why??? Thanks, Betsy P.S. This problem stems from the following situation: I have 3D data which is regular in x and y, but the delta in the z direction varies. I want to take a series of slices in the z direction and run them through a macro which requires a regular field and then Stack the results together. I haven't been able to create a regular slice, even though the data is regular in x and y.
