Hello,
I have a cube primitive with multiple width/height edges to cretae a body of an object. I need to move the points and edges to shape the object.
In the point edit mode, Side view, I select some of the vertices of a given vertical edge and want to rotate only those selected vertices, with the rotation axe positionned on the first selected one at the bottom, which is in fact near to the middle of the edge, the other points below, not being selected.
But as I am in a Cube, the rotation axis is positionned by TS 7.6 in the left low corner of the Cube.
How can I position the axis exactly where I want ?
Probably in the manuals and courses but did not see it.
Thx

you need to use the axis tool. Its in the main workspace menu bar(within the window), second flyup along I believe(bit vague I changed my default settings ages ago)
IK
Anyway it looks like

Thanks Igor for your response.
Actually I did click on this button, but after nothing happens ; the axis symbol does not move. I have tried to drag it with the mouse, with CTRL or w/o, with shift or w/o ; it does not work. I also tried to just click in the view ; nothing.
Any idea what is the next step after we click this button ?
Thx

Got it, seems I was not clicking the right widget ; the axis was hidden behind a plane in my view. Now I just have to click on the arrows of the axis widget to position it as needed.
Thx

use a transparent wire setting for scene render or obj render setting so you can see the pivot(axis)
then select object you want axis to be active in then click the 'axis tool', you should have a widget show up that represents the pivot(axis). it can be used to move axis or you can now use object info panel by using down arrow key to access info for pivot(axis) values. |

Stan,
I finally managed to position the axis correctly using the axis tool. However, it does not work : the vertices of my object are selected, the axis is well positionned to do the rotation, but when I rotate the axis tool, my vertices do not move at all. I have tried in all the 4 views and with all the axis.
Do you know why this could happen ; is there a locking feature for an object which I would have inadvertently activated ?
Thx

I've only been using tS for six weeks, but I don't think the axis tool works this way. It works fine for whole objects but not for selections or individual vertices. What you want to do would be trivial in Blender but tS just doesn't work this way. Using the axis tool you can "spin duplicate" objects just like in Blender but it won't work for vertices. Hope I'm wrong. |

I've been having a poke at this problem, just trying to figure it out.
Once you move the Object's axis with the axis tool, (and why doesn't Grid Snap work on it, anyway?);
then you enter Point Edit via right click, select the vertices you want to rotate,
and finally, use either the widget or the Object Rotate icon to rotate the verts. ( not the Axis Tool)
The problem is, I can't figure out how tS is determining the axis of the selection... you can see it jumping around because the position of the widget changes as you add or subtract points to the selection.
Changing World/Object/Screen/Tangent modes seems to have no meaningful effect, either.
Does it even use the object's axis to determine the axis of a selection? I can't tell.
Is it 'averaging' out the selection axis depending on the position of each vertice? Maybe... !
Does it depend on which vertice you selected last? ... Possibly!
I sure do miss the old Cage style widgets, I can tell you that for sure! |

Grid Snapping works for me with the Workspace Axes tools. I may be wrong but it seems to me that the Workspace Axes tools work just like the Model's Axes tools. Only difference is the Workspace Axis widget sometimes does not show in Solid mode. You can either enter Point Editing for the object or change the Object's/Scene's Render Attributes. |

I respectfully beg to differ- Grid Snap has zero effect on the Axis Tool in Workspace, regardless if I use the Object manipulation tools or the Axis widget.
Model side works as expected.
Edit: Also, I noticed the 'Move axis to center of object' tool is missing from Workspace axis tools.
Re-Edit: Thanks to Steinie, I found out that 'Move Axis to center' is now titled 'Normalize Orientation'; which sounds like it adjusts the rotation, but actually centers the axis.
Was it too simple to just use the word 'center?' (See also: Encapsulate) |

I think this is exactly the problem. There is no user control over the widget location (unlike the world axis). If you could select one vertex and fix the location of the widget there it would solve problems like this post. |

I agree that being able to locate the widget to static location would make live easier in such scenarios. |

I am not sure if this will be helpful or not in your particular case but in the Manual - Chapter 3 page 222 within Point Edit Snapping there is some information about Axis Aligned. Note that this is reference to Inference Lines.
Axis Aligned – When this is checked, lines are drawn based on the axis of vertices and snapping occurs to those lines. When unchecked, these lines are not drawn. This is the same parameter as Axis Aligned on the Default aspect – changing this parameter in either aspect will change it in the other. |
