Hello, I am working on a project where I am creating a custom toolbox that includes several models and two python scripts. I have folder with the toolbox in it and the a subfolder for the Python scripts. Attached is what my toolbox folder looks like. I am doing the tool creation in 10.6 but my partners on the project need a working toolbox in 10.2. When I save the toolbox back to a 10.2 toolbox and share the folder the tools for all of the models associated with the scripts require a repair. Repairing is no problem but for the final project the tools need to work right out of the box. Does anyone have any advice on how i can rectify the problem of the tools breaking. Viewing the toolbox in my 10.6 interface even after saved back to 10.2 shows everything is fine but my partners in 10.2 see only broken tools for the ones associated with the scripts. Thanks

Hi Richard, Thank you once again for your great insight on this issue. Would you have any pointers on using a cursor for this? I have essentially the entire road network of California, and need to calculate the slope for very road segment so a cursor method, or dictionary may be more efficient. while I have used ArcGIS desktop for many years, I unfortunately have very little experience using arcpy.

Thank you Dan! By applying this method would one be able to claualte slope for a sgeemnt that was between two points on the line. For exmaple if say the line was joined to 46 points could the slope of the road between point 2 and 3 be calculated?

Hi, I have a set of points that are gps points a plugin hybrid vehicle has traveled. There are a set of attributes such as speed, battery power, etc for each point that I would like to maintain when i convert the points to a line feature class. Is there a way to do this? When I use the points to line conversion tool I get just one polyline that is has not maianitained the attributes of the points. Thank you for any help or suggestions! John

Richard, Thank you for the thorough resposne. I will give this a try!!

Hi, I am currently trying to calculate the slope of roads using certain plugin hybrid vehicle trips. My data are currently a point shape file that is recorded every 1 second. The points have several attributes but the important ones are elevation at each point, and vehicle speed. I would like to calculate the slope by doing something along the lines of: calculating slope between point at time T and T-1 as (elevation at time T – elevation at time T-1) / distance * 100 and the slope between point at T and T+1, and use the average of these two slopes as the slope of point at time T. If the vehicle speed is 45 mph (72 km/h), then the distance between each two points is 72/60/60*1000=20 meters. Unfortunately I would need to reference the attributes in rows above and below in field calculator and I am having a lot of trouble figuring out how to do that. Is it possible in the field calculator using either python or vb script? Thank you!
