Move multiple points in a polylines

[BaNoBi]

In response to this thread: http://www.cambam.co.uk/forum/index.php?topic=4855.msg36700#msg36700

It allows the user to select and move multiple points in a polyline when editing. Select one or more points with the mouse, select the starting point and the last the end point.

1. Install the dll into your CamBam 'plugins' folder, restart CamBam
2. Draw a polyline, or convert a circle etc. to polylines (it only works with polylines)
3. Select the object so it's highlighted (one object only)
4. In the context menu "Polyline" or the sub-menu "Polyline" in menu "Edit" a new item will appear, "Poly Move Point"
5. Click on "Poly Move Point" or press the shortcut (default F2, can be configured on menu Plugin > MovePoints Config) to run the plugin.
6. You now enter an edit mode "LeftClick to Select/Unselect a point, Ctrl + LeftClick to set the start point, Esc to end"
While in the edit mode you can zoom in or out.
Just click on the points for select or unselect, after press Ctrl + LeftClick for set the start point (reference point for the movement).
7. After setting the start point you move on to the next step of the edit mode "Start point set (X,Y) please select the end point, Esc to end"
8. Click on the view for set the end point of the movement.
9. Just click on the Esc key for done the editing.
10. Now you are back to CamBam

Try here, right click context menu, 'Poly Move Points'

[dh42]

Ah ah !!  Yes, I can search a long time in the plugin menu

I've found a bug ; look on the file, one point is not selectable ; if I moves slightly the shape, it works ..

Vasco, it is possible to do that the start point for moving can be anywhere and not necessary on a node ?

Sorry, my mistake. The new menu entry is on context menu Polyline and the menu edit.

EddyCurrent is correct.

Sorry, my mistake. The new menu entry is on context menu Polyline and the menu edit.

Ok   .. but for me it is only in the context menu, not in the main edit/polyline menu.

a second bug ; if I run the plugin on any existing file instead of a new file, CB crashes when running the plugin .. (even on a file where the plugin has never been used)

Hello,

Yes, better 

It do strange things if we click more that one time to place the second point ....
(I think that the offset is added to the last click position instead to the start point position)

Ex: point to move is at 0,0 ; start point clicked at 0,0 too

2nd click at 10,0 -> OK the point jump to 10,0
3rd click at 20,0 -> Wrong, the point jump to 30,0

New version 2.1 on the first topic.
