surface through points
hi there,
i have 30 land surveyed points (x,y,z) in solidworks that i would like to create a surface through.  the points came from a land surveyor and i now need to calculate the volume of the surveyed land.  i am sure sw can do the trick?
any assistance would be appreciated.
regards
check out our whitepaper library.
point cloud macros;
corblimeylimey,
thanks for the helpful macros.  once the points are in solidworks, do you have a tip to create a surface or volume from these points?  i can manualy (2 hours of work) create 3dsketch lines between the points but how does one create a surface from this?
regards
corblimeylimey,
thanks for the macros.  just a question, once the points are in sw, how does one easily create a surface?  i can if required create 3d sketch lines in triangular format between all points.  from these lines can one then create a surface?
regards
after importing the points, create a suitably shaped sketch surrounding them and at an elevation/altitude to suit the upper level of the volume required (surrounding terrain ?). the filled surface tool. the edges of the surfaces will be the patch boundary and the 3d sketch points will be the constraint curves. you may have to tweak the 'tangency' options to arrive at the correct surface shape.
create a surface over the resultant shape and form a solid. the volume of the solid can then be obtained with the measure tool.
  

corblimeylimey,
thanks alot for the help, it work perfectly.
