import points from xls files

[marcobrt]

hello to all guys and compliments for the forum.
My problem is very simple, I have a xls table where I tabled the profile of a cylindrical cam, the values of the first column are degrees and in the second are mm, how do I tell inventor that the data of the first column are degrees?
I can import the points though I have the flat profile, on the x mm axis and not degrees and on the axis y the various values of the diameter.
I noticed that from the 2009 line there is the option "crea spline" automatically, which instead 2008 does not have....sig Mr.
thanks in advance

to import points into inventor you need a table where the first column represents x the second la y the third la z. points, in fact, in the space are defined by three coordinates, of course a point can not rotate on itself according to a given degree... .

the points, in fact, in the space are defined by three coordinates

Allow me to complete the sentence: in the polar coordinates, a point is uniquely determined non x,y,z bensi' It's just... from a corner and a carrier.. .

I would like to recompose the profile of the cam with a polar coordinate and a vector, the first column expresses the degrees and the second distance from a single point, a bit like xls when you tell him to insert a chart "radar".
Does anyone know how to do it?
Thank you.

in a "polar" coordinate system, inventor like any other software uses a "chartesiane" coordinate system.

 

[AntonioV]

inventor come any other software uses a "cartesiane" coordinate system

this time not complete, but I must correct that "anything". . .

staying in the autodesk house, an autocad draws indifferently in:

• coordinates related cardssiane
• relative polar coordinates
• relative cylindrical coordinates
• coordinates relative spherical
• polar coordinates and topographic angles

I don't know inventor, but it seems strange to me that it only limits itself to the Cartesian. . .

Go be....:biggrin:
Anyway I understand....
I turn each point from polar coordinates to Cartesian and amount those!:finger:
Hi.

I mean a three-dimensional parametric modeling software (inventor, sw, catia etc.).
cmq if you stop for a few seconds on the key import points and press f1 the guide is very exhaustive
