Constrained

 

 

 

 

This command allows you to create a surface constrained by boundary curves, constraining curves and constraining points.

 

Creation Stages / Use:

 

Click on the icon or choose the command Surface > Constrained... from the drop down menu.

 

  1. Check Initial surface if needed.

  2. Check the types of constraints that you wish to use.

  3. Select the profiles or points for each one of the constraints.

  4. Validate.

 

Available Options:

 

 

 

The initial surface allows to define a parametrization by projection of points on the surface.

 

 

 

Check the type(s) of constraints that you wish to use for your surface.

 

Constraining boundary curves:

All selected profiles must define a closed bound. These curves determine the outer bounds of the surface.

 

If the selected cruves don't define a close bound, the Close boundaries allows to automatically create line or a bspline curve between the origin of the first selected curve and the extremity of the selected curve. In case of bspline curve, the graphical handles allow you to set the tangency (direction and ratio) according to the extremities.

 

Constraining curves:

The resulting surface will pass through all of the curves displayed in this list.

 

Constraining points:

The resulting surface will pass through all of the points displayed in this list.

 

 

You can remove elements from the list by selecting them and then by using the "Delete" key on your keyboard.

 

To select several elements in the list and to delete them all at once:

"Ctrl + Left-click": Each click on an element in the list adds it to the selection.

"Alt + Right-click": selects all elements included between the element clicked and the previously current element in the list.

 

 

 

Advanced options:

 

 

 

The constrained surface calculation is optimized for the performance (at the expense of quality).

 

 

 

The constrained surface calculation is optimized to produce a better quality surface.

 

Modifications:

 

It is not necessary to use all of the types of constraints in order to build a surface. You can use only one of the three if you so wish.
