Hi Roygee!!

I’m not sure why, but I did not get an email to tell me about your last post. If all went well, I have a screen capture from ScreenHunter attached to this post. I am perfectly clear on what you are saying. That is not what I was looking for. I am dealing with the distorted cylinder from your previous post. I think it is #3.

The screen capture here is the result of a mathematical approach to the problem. I created a spread sheet into which I place the X, Y, and Z numbers from the property sheet. I can start from the top or the bottom of the model, so let’s use the 0 Axis as my example. If one of my cylinder devisions is running across the cylinder and therefore 90 degrees to the cylinder length, I know that the X axis for the numbers in the X of the property sheet will all be 0 since the line is set there.

What can get messed up, are the Y and Z values. The whole cylinder is not a complete mess, but there will be points that are out of alignment on the Y and Z axis.

So, if I start at the bottom of the model, I know that my X is 0, and my Y and Z are on a reference drawing and therefore should be positioned where they should be. I enter the X,Y and Z from the property sheet into the “Bottom” line of my spreadsheet. I skip one horizontal line and therefore land on the third line from the bottom. I enter the X,Y and Z from this point into the “Top” line of my spreadsheet. I add the x’s to each other and divide by two to average them and then add this value to the bottom x value. I do the same for Y, and then for Z.

Once I have added the six numbers, my spreadsheet shows the values to enter into the property box for the point that I skipped. It takes a little time, but if I work my way through the point, I will have them all lined up into a clean skin on the fuselage.

(Added in edit) I have a

X Y Z

Top .58 2.846 -1.081

Bottom .58 2.739 -1.168

# to Enter .58 2.792 -1.124

Formula = ((Xtop-Xbottom)/2)+Xbottom, ((Ytop-Ybottom/2)+Ybottom, ((Ztop-Zbottom)/2)+Zbottom

I have a slope across and along the wings to deal with, so I will note the highest point, and then the lowest point. If I set equal measured distances for a grid that covers the wing, I can mathematically calculate what the values need to be to get an even slope in both directions.

I have some photos that I can mark up with grids to see what the actual slopes are and hopefully I can determine the true slope angles to use.

I am also not doing the model in one shot. I have restarted with just the fuselage, and then I will do the basic body, next the engines, then the wing extension, tail wing and verticals.

I think I have an answer to my question that I can work with. I thank everyone for their input, ideas and help.

Can functions be built for Hexagon? I’d love to be able to enclose three consecutive points and have a button to push that will then tell me the numbers for X, Y and Z that I need to enter for the point in the middle.

Please post if you have any questions or concerns with what I am doing here.

Thanks

Tim
