[Feature Request] Add a way to align section views to regular views

[NewJoker]

Please test the macro. Is it worth to create an extension tool in TechDraw ? Pease tell me your opinion.

I tested it. Works just as expected. It would be great if you could turn this into a built-in functionality - would be very useful.

Here's a simple test example:

I also vote for a built-in functionality ... however I would suggest to not create a new command but rather enhache the existing "Position section view"
Cheers

Find attached my version of the macro (hopefully) doing the task:

Workflow:
- select one point in the base view
- select the corresponding point in a section view
- start the macro

The section view is positioned at the correct perpendicular position.

Attention: There is no test, whether the correct objects are selected.

Please test the macro. Is it worth to create an extension tool in TechDraw ? Pease tell me your opinion.

Tested, and it is extremely nice. I would love having it added by default as an Extension Tool.

Question, how tricky would it be to allow for one or both of the selected geometry elements to be a line segment, and then create a temporary vertex at [min x|max x], [min y|max y] (depending on what's more appropriate based on the position of the two views) that is finally used to align the views? If this functionality was added, I would not mind if the align function was split into AlignViewX and AlignViewY

Nice macro.
It would be very useful to obtain the two alignments, x and y, and even make the points coincide.

A short script to coincide two points of two different views in TechDraw.

Code: Select all

'''
Coincide two TechDraw views
Workflow:
- Select one vertex in first view
- Select one vertex in second view
- Start the script 
'''
sel0 = Gui.Selection.getSelectionEx()[0] 
vetrex0Name = sel0.SubElementNames[0]
view0  = sel0.Object
pnt0 = view0.getVertexBySelection(vetrex0Name).Point
scale0 = view0.Scale

sel1 = Gui.Selection.getSelectionEx()[1] 
vetrex1Name = sel1.SubElementNames[0]
view1  = sel1.Object
pnt1 = view1.getVertexBySelection(vetrex1Name).Point
scale1 = view1.Scale

c0 = FreeCAD.Vector(view0.X,view0.Y,0) # view0 center on page
p0 = c0+pnt0*scale0 # base point of view 0 on page
c1 = FreeCAD.Vector(view1.X,view1.Y,0) # view1 center on page
p1 = c1+pnt1*scale1 # base point of view 1 on page
delta = p1.sub(p0) # the moving vector

view1.X = view1.X.Value-delta.x
view1.Y = view1.Y.Value-delta.y

Wonderful !!! Thank you!
I need to learn FreeCAD scripting and macros ...

@edi Would you be able to implement this macro as a built-in feature ? I think that it could be very useful. Manual view alignment is quite tedious.

Find a reworked version of the PositionSectionView tool in the next weekly release.

The tool has been extended by the possibility to align inclined section views and section views which have a different height/width than the source view.

Explanation see in Wiki, Usage 2: https://wiki.freecad.org/TechDraw_Exten ... ectionView

An example how to align a section view having a different width than the source view:

Thanks to all who helped, merged and tested the tool.

Thank you very much for implementing this. It's super useful.
