‘fairi’-ing in not all 3 directions

[GLS]

Hello,

 

Recently, I did try to use the FAIR option in DelftShip Pro.

However, I did see that all 3 the direct6ions were influenced.

 

Is there a way to loch one or two directions so these will keep the original values?

 

e.g. when points are on the x-axe (cross-beam; Dutch: ‘spant’), I would like to keep this value, while the Y- and Z-value might change, but the result is that also the X-value is slightly modified, and not exactly on its original point anymore.

 

Can someone help me out?

Hi GLS,

Auto-fairing will always try to optimize the points in 3D. There is no way that I can think of that will allow you to restrict this.

Hi Maarten,

 

That’s a pity.

 

Let me try to explain my case:

I did design a hull, based on fixed x-values (position of ‘spanten’):

After fairing this hull, lots of positions have been changed, so it becomes difficult to place the ‘spanten’ in the right position:

As you can see some points have major different position (left or right side of the picture), while lot of point do have minor changes.

 

Also look at another topic of mine, to put points which are used in one layer, on a curve of another layer:
