The guidelines I use for "small" angles are: The difference between the radian value of the angle and sin of the angle is close enough to zero The cos of the angle is close enough to one. In the unlikely case you are not dealing with small angles here is a list of some papers I found helpful when working on 3D transformations (rigid body): "Deakin, ...
I found out that if I enter the .asc ending for the output file it will generate an ASCII file. However, it would be nice to know another way as well.
We have used ArcMap 10.3. Calculated (1) feature to point with inside option (2) feature to point without inside option (3) centroid by calculate geometry. Points from (2) and (3) share location, sometimes these points are outside the polygon. (1) creates points inside polygons, as expected, mostly identical with points from (3) and (2). Sometimes points ...
In order to be able to use a Basic level license of ArcGIS for Desktop to perform intersections (or other polygon overlays like Union) between more than two input feature classes I would recommend performing them pair-wise i.e. for four input feature classes intersect the first two, then intersect the other two, before intersecting the preceding results. ...
