I have ~200 imported datum points, in the shape of an airfoil, that I would like to connect with a spline, and extrude to make a wing. Is there any way in sketcher to select all of these datum points as references without individually selecting on each one?
I believe this is dependant on how they were exported, copius data or just a point cloud. My past experiences have been such that I want to do each singular point to insure that they are connected in the proper lateral orientation I am desiring.
It is ok ifI have to select them all to connect the spline, but to make them references in sketcher, I would need to select them all one by one also. This would mean clicking on over 200 points once to select them as references, then selecting them all again, to connect the spline. It would seem to me that picking multiple points for reference would be easier that individually selecting them all.
if they are flat... z zero and you have them in a file with x y z format
you might ..might mind you .. is create a spline ...point at each end
sketch...co-ord sys ..at your xy zero .. right click the 2 point spline
select modify > coords tab.. pick the co-ord you inserted
then read should be available... read in the points and it will say different number of points... okay.. and that might get them.... you may run into trouble if there are too many points...200might be the limit... worth a shot, would beat picking them all
Funny older versions of ProE allowed for larger point files
For reference sake, got hold of a friend who does airfoils for a living and asked about point limits what's the take on file size, what does one really need He said;
If done correctly, 200+ points is good definition. The problem is, you
can start to introduce waves if you overdefine an airfoil.
So youhit it right on the money Ryan
I would think that would also apply to hull/PWC design as well , just low flying planes
Post might be a little old, but I have a problem with what wsylvester was suggesting.
The curve color blue (points are red) cannot be extruded. I have the following error message:
incomplete section: <a>Section must contain geometric entities for this feature.<br style="color: rgb(0, 0, 0);"><br style="color: rgb(0, 0, 0);">I find it pretty annoying, please find attached a screenshot.
if it is ...look at your point data..too bad that link is dead now
but it's based on the length being 0 to 1
so there is a top half and a bottom half..two splines
in sketcher..place a sketcher csys ,now draw a spline ,freehand some points so that you know which is top ...end it on your axis...do the same for the bottom spline end at the same point
modify your length from the csys to the endpoint of the splines to 1 then modify the top spline ..file..pick the csys..then open your top data..then the okays
you should have your top ..do same for bottom spline then if your want something other than 1 you modify that and it maintains the shape..or whatever your max value was in spline direction.
if you modify the length you can edit definition and output the point values of the new section if you like..hth
Ive now i wish i could apply this to something. Might read up on the joys of model plane design and then see if i can get sections laser cut to make a nice model
