Hi,
I have a spline ( front plane ) which I need to move entirely without deform; I move it by its 2 extremities coincident to a perpendicular plane ( plane1 // right plane )
When I move the plane1 the point of the spline dont move so how to make them unlocked to there coordinate ?
I've tried to lock the handles but without success ...
Thanks by advance
Eric, if you know how much you want to move the spline, you should be able to do it from within the sketch using the "Move" command. (Tools > Sketch Tools > Move). Mine shows up on my Sketch tab of the CommandManager, below the Linear Sketch Pattern button.

Sketch Block
Good thinking, also derived sketches are pretty useful
Sketching should be controlled by dimensions and made for ease of change...
It sounds like you want to edit the Plane, and have the spline move with it without deforming? If yes, you have two choices that I see.
1. Make it a Block, as J. Mather suggested. (If you do that you may need to re-establish the ends coincident with the plane after turning it into a Block.)
2. Completely define it's position with dimensions, as John Stoltzfus suggested. However, keep in mind that you'll have to be careful that you dimension to the plane that will be edited.
Thanks guys,
a picture is better :
as you see I've made a "nurbs tube" ( this is a cutaway view ;-) ) and as the dome function don't works great as the section on plane00 is not a cylinder I've decided to create my own dome ( this dome is not what I want - it is just an example )
The block solution works for the spline on plane1 but the blue 3Dsketch spline is not allowed to become a block so the dome become deformed ( the mid point on the 3D spline does not move ) if I move the plane00 in order to change the rear size of my nurbs tube
At the end I make an intersect to create the dome volume : is it possible to creat a block ?
I guess no as it is the intersect's sketches to be "blocked"

but the blue 3Dsketch spline
Appears to be planar to me.
If so, why did you create as a 3D sketch rather than as a 2D sketch?
Can you attach your *.slprt file here?
looks planar but its two extremities are not on the same plan
Maybe I can create a plan with the good angle ? I'm going to check
here is finaly a "good" solution : creating an inclinate plan in order to get the 2D spline and made 2 blocks for creating the loft dome
now I can move the plane00 without deforming the "dome"
Thanks guys
here is a solution but not very simple : using a second plan parallel to the plane0 and made coincident the mid point of 3D spline ...
NOT USEFUL
my solution was limited as if I modify the nurbs tube the splines's dome loose their anchors ...
So I change my nurbs tube modeling : instead of Surface-Loft I use Boundary-Surface and now I 've a single tube with the rear dome included
but now I can't create a "merged solids" when I mirror the half nurbs tube ???
I can mirror it ( in 444 file ) but not with the "merged solids" option so if I try a new intersect with additionnal new part there is an intersect bug
With 111 file with Surface-Loft it is possible
The half nurbs is made by intercept two solids : one a little bigger than the other one and both on the same PLAN DE FACE
More crasy : I can mirror each solid with the "merged solids" option but then intersecting them to create the "hollow nurbs tube " refuse to work : REBUILD ERRORS " during geometry integrity checking this feature is found to create invalid geometry"
It is annoying because in the intersect window I see exactly the internal part I want to eliminate BUT when I clic OK REBUILD ERRORS message...
more crasy : in the intersect window if I select to keep the internal part I want to eliminate I can merge ......
