AutoCAD Map 3D

[#1]

Is there any way to multiply the value of Z coordinate for many points selected, in the same time? For example, I selected many points, and need to double their Z value, but on an easier way, not one by one? Thanks

One way is to export those points to a shapefile, then perform the calculation in the .DBF (in Excel or similar), and _MAPIMPORT the edited shapefile back to Autocad.

Thanks a lot. I'll try, and hope it will work, cause I'm beginner in Map 3D. Thanks again.

Please pay attention to this point: if you manually edit a .DBF file belonging to a shape-set, you can add or erase columns in the spreadsheet, but it's NOT allowed to add or erase rows.

If you only need the calculation, export the pint with the z value as a property, put  the sdf into a map and open the data table, calculate z*2.

Do you need to move the points or create a new set of points at the new z value?

Thank you

Actually, I attended to move plenty of points along the Z axe. To duplicate Z value for all the points in the same time, but as I'm a beginner, didn't know how. I tought, it must be that it is easy. Maybe it actually is, but when you are not familiar with Map 3D, it seems dificult. Now I have some inputs and ideas, so I'll try. Of course, it needs much more time for me. Thanks a lot

I believe that a recent problem with the suggestion of editing a .dbf is that MS Excel 2010 no longer allows you to save back in the DBase IV format.  However, a work-around I found was a gentleman in Australia selling a "add-on" re-enabling this feature for $30 US.

Just want folks to be aware before investing too much labor.

OpenOffice will allow a save back to .dbf also.(and it's free and will handle the native .xls files as well)

True, thanks for bringing it up - I use it on my personal machine & forgot to mention....
