From Javafoil to Pro/E Wildfire

[Arxane]

Good day, everyone.

I'm having some trouble inserting some data into Pro/E. I need to use an online Java program called JavaFoil to create a 2D wing, and then use this 2D structure to create a 3D extrusion in Pro/E Wildfire.

The process has been done before, but the people who have done this before are a little busy to help me right now. Basically, Javafoil creates a wing represented by a set of table data. This data is then sent into a Microsoft Excel file, formatted a certain way, and then inserted into Pro/E somehow. In fact, I'm pretty sure that the method described by Jeff in this thread is the method I'm looking for. However, I'm still unsure of how to transform the 2D wing data into a 3D wing extrusion in Pro/E. I've tried following Jeff's instructions, but they're a little vague for me and I'm sure I just miss what he's trying to explain.

If anyone can help me out, I would be very grateful.

Arxane,

You need to create a sketch of the airfoil first. Before this though you need to format your data points. I use word pad...create separate data tables for the upper and lower splines. For example,

X Y Z
0 0 0
1 0.5 0

and

X Y Z
0 0 0
1 -0.5 0

When you save each of these tables separately save as "upper.pts" and "lower.pts" and include the quotations.

Now in pro/e create a new sketch, and insert a coordinate system and reference "construction" line at y=0. arbitrarily create a spline that has 3 points (usually 0,0 0.5,1 and 1,0). In the right hand tool bar, there is an icon to modify dimensions, click that and there will be an option to enter data points from file. open the "upper.pts" file and select YES. This should produce the upper half of the airfoil. Repeat for the lower half and save the sketch. Now you can create an extrusion, in the menu bar choose sketch from file, insert the sketch and extrude it.

Hope this helps,

Chris

By the way, the data points for the lower spline must start from 0,0,0 as the upper points do...I think JavaFoil's order is the other way around

I'm trying to do something very similar. I'm tying to revolve a modified sine wave to make a model that looks like a ripple. I've constructed the data set in Matlab and am trying to follow the above technique but have run up against a wall. Once I'm in the 'modify' option for the spline I can't pick the local coordinate system I've defined. I can't pick the global coordinate system either. Without this step the little folder icon remains grayed out and I can't import my data. Are there special considerations when defining the local coordinate system? Please help. Thanks

You need to create a sketcher coordinate system:

In the sketch toolbar, the sketcher csys option is in the flyout with the sketcher point.

Good luck

Awsome, thanks a lot!
