See this ESRI blog for an answer. Map scale (km/cm) * Viewing distance (cm) Be careful with the tape measure between your screen and eyeball. ... View more

I see you've got this figured out, but for this, why fight with the extents at all? Just buffer the study area, clip those streams in buffered area, buffer streams, clip back to study area. Perhaps it takes more time to buffer the study area than to clip a bunch of extra streams. Maybe it's six one way, half dozen the other, but I'd guess dealing with the fewest streams possible would be a good idea. ... View more

I suppose since you're expanding the extent by some number in all directions, you could just add/subtract that number to/from your original extent, rather than running a buffer process at all (I'm not sure if that's what Dan was getting at. If so, carry on). ... View more

You can make use of the buffer method of the polygon object to make a new buffered polygon geometry: polygonTmp1 = arcpy.Polygon(origExtentPts) buffPoly = polygonTmp1.buffer(extBuffDist) newExtent = buffPoly.extent # this returns an 'extent' object. May have to convert to 'polygon' ... View more

Rather than delete your unused data frames, move them off the page (elementPositionX and elementPositionY). As for implementing ArcObjects through Python, it is somewhat difficult to get set up, but it can be done. ... View more

Do you want a convex minimum polygons or concave hull (or neither), and what license level do you have? ... View more

Because TINs will appear sharp at any resolution. Whether or not the triangles will work for your map, I don't know. You can also try Resampling your DEM raster to a smaller cell size. ... View more

Have you considered converting DEM to TIN? Requires 3D Analyst or third party tools.. ... View more

I don't believe you can directly change the data type from point to multipoint, but you can create a new feature class of type multipoint, then copy/paste the point features from your point to multipoint feature class. You can then transfer the existing point attributes to the new multipoint geometries using Spatial Join. * I'm not sure if there is a single tool that will combine the above steps. I would have guessed Append, but that does not work between point to multipoint feature classes. ... View more

As this question does not relate directly to ArcGIS, although you may get any answer here, you should consider asking questions about general Python on Stack Overflow. ... View more

Glad you figured it out. As a postscript, if you're interested and using 10.1+ (I think), you may want to look into using arcpy.da.SearchCursor(). They're faster and don't require "nexting". ... View more

There is an intersect method on the arcpy.Polygon() object that you can use for polygon-level intersects between individual polygon features, which you can get to using a cursor. ... View more
