Eric, thanks for your input! I had something like that in mind too. A potential problem with that though is that it runs the risk of creating abrupt changes in the surface around the points after �??burning�?� the dem. I will try that and also to do a focalmean on the resulting surface, probably iterating this a couple of times. As you can tell, the pixels under the input points are more important than the rest of the surface. I realize this might sound a little strange but that is the directives in this project. Do you have an idea for an interpolator that will give me the smallest difference between the input points interpolated value at that pixel? Thanks! ... View more

Steve, Point to raster is worth a try, in combination with other tools. I do need a surface that covers the entire area. Why do the values have to be the same as the interpolated cell values? Well, it is a requirement of the project that's non negotiable:) . I also can't shift the position of the input locations. It seems like some combination of methods/tools might be needed. Basically I start with XYZ points and need to arrive at a surface, but what I do in between doesn't matter as long as the exact Z is kept in the pixels where the input points are. ... View more

Thanks Steve, now I understand how it works. The question remains if there is a way to create a surface where the pixel "containing" the input point gets the exact value from the point. From what you have said it doesn't seem so... ... View more

Michael, The resulting surface needs to be modeled like this and also needs to be a raster. I thought about starting with a TIN but then I�??d need to convert it to raster which involves an interpolation anyway. Steve, No, my input points have no distinct pattern to them so the pixels created are not centered below the points. When you say �??The cell center is where the prediction is being made.�?�, to my understanding that means that the interpolator uses the point (which might be located at the edge of a pixel) to read the value, draws a curve to fit through the point and assigns the pixel the value that is represented by the curve at the center of the pixel? See my poor attempt at art-work in the attached image. Is this a correct understanding? And most importantly for this problem, is there any way to let the pixel get the exact value of the input point, in the image 123? Also, I missed to link to the thread in the GA forum, here it is: http://forums.arcgis.com/threads/29053-Spline-not-working-as-Exact-interpolator?p=144981#post144981 Thanks guys, I am really grateful for any help you can give here! ...

You cannot edit multipatch vertices at 10. You can check to see that they are closed or not with the Is Closed 3d Tool, but editing vertices of a multipatch is not possible.  You can move the multipatches around and up and down via the 3d Editor Toolbar.  I am also including the help on the supported multipatch edits.  I would recommend checking to see if the multipatches are closed, because they will error out if they are not closed. Jeff, I am facing a similar problem where I have multipatches created from TIN�??s that I want to intersect with another Multipatch with the Intersect 3D tool. My problem is that the Multipatches aren�??t closed and like you say there is no way to edit Multipatches in ArcGIS to make them closed. My workflow is: - Create TIN�??s from XYZ-points. - Extrude the TIN�??s with Extrude Between to create Multipatches representing volumes. (Create a cross-section Multipatch through digitizing a line, extruding and saving to multipatch by 3D layer to FC) - Intersect my volumes with the cross section Basically, I am following the workflow mentioned here: http://forums.arcgis.com/threads/6973-Creating-Cross-Sections-in-ArcScene?p=67522&viewfull=1#post67522 So my question is whether there is a recommended method out there that will let me create closed multipatches when I�??m going from my XYZ points to volumes? Or if there us a recommended tool for closing Multipatches through editing? Although I fear this might be a very time consuming task when the multipatches are created from extruded surfaces.

Hi Kevin, Use the Select Data tool, found in Data Management/General toolset. That will let you keep working on any output from the Network Analyst solvers. Cheers, Nooski ... View more

Adding to my post above, there's an explanation in the help why you need to handle the result object. Have a look here: http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//002z0000000n000000.htm In the note under the "Getting results from a tool" heading, it says: The result object's getOutput method returns a Unicode string from result objects that have output values. This is an important consideration when running a tool such as GetCount, which provides a count of records in a table, or CalculateDefaultClusterTolerance, which provides a cluster tolerance value. To convert the value to the expected type, it will have to be converted from a unicode string using built-in Python functions such as int() or float(). ... View more

Hi Hydronaut, What specific problem do you have with the code in the link? I believe that with some of the changes suggested in the comments in the link you sent, this should work. I was removing empty layers from mxd�??s with a similar method. What I found (in v.10) is that you need to make an integer of the results object from GetCount_management. So if you look at comment #5 in the link, which says: result = arcpy.GetCount_management(fc) print result if result == 0: print fc + �?� is empty.�?� arcpy.delete_management(fc) Change that to result =  arcpy.GetCount_management(lyr) count = int(result.getOutput(0)) if count == 0: arcpy.mapping.RemoveLayer(df, lyr) print "Removing " + lyr else: print "Keeping " + lyr In the code above, substitute arcpy.mapping.RemoveLayer for arcpy.Delete_management. Also, you might need to handle FC's inside feature datasets like the first comment suggests. ... View more

Thanks anant! That works! What is the plan for 10, will this be fixed in the future? Nooski ... View more
