Danke ihr beiden.
@Tiles
ich brauche es nur auf eine Kommastelle genau im Millimeter Bereich.
Wenn ein Holzprop von Hand geschnitzt wird, siehe hier:
http://www.aerodyndesign.com/PROP_10/PROP_10.htmdann geht das warscheinlich eher im Millimeterbereich ohne Kommastellen
Versuche gerade die Jungs von Freecad im deutschen Forum dazu zu bringen dass sie mir eine stichwortartige Anleitung basteln
Ich komme sonst nie zum Ziel...
Bei meinem Propeller Programm hat das ja auch super geklappt...soweit eben die Anleitung da war...
" For use of the text *.txt files with the Rhino3D program Rhinoceros® You need to make and save the files, it is made my just pressing the "Create .txt files" button and save it to a convenient place on your computer, this creates the 7 files needed to make a propeller blade. Then go to Rhinoceros®.
1) Start a new part file.
2) File / Import / chose Points file type (.txt .xyz).
3) Now go to the file folder where you have the first .txt file stored. Double click on it.
In The Points File Import Options, check ”tab” then click OK
4) Curve / Polyline / Through Points: select points to build curve through. (Start at trailing edge point and go around the nose and back to last point at the trailing edge opposite from the start point) Press Enter when done:
Draw a straight line between the 2 trailing edge points or draw a tangent arc (Arc: Tangent, Tangent, Radius) Then Ctrl + j and join the two curves.
Next do the same for the following 6 station text files entering them sequentially from the first station to the last. The first station is being closest to the hub.
5) Once all the station profile is in, you can then loft a surface using the station profiles you have now entered. Surface / loft do this.
6) Select each Station profile in the order that you brought them in to Rhinoceros®.
7) Now you maybe want to make a three-blade prop, to do this all you need to do is Transform / rotate / select object to rotate / Copy =Yes / set center of rotation / angle of rotation
(2 blade is180deg and 4 blade is 90deg) "
