Select/Pick object in a detail from within a layout view


(Willem Derks) #1

Hi,

I’m looking for a way to pick/select an object within a detail while working in a Layout view.
Specifically I’d like to pick a single object visible in the detail to use for annotating usertext with a leader.

Can anyone point me in the right direction how to do this with python/rhinocommon?

Thanks

Picking objects from Layout space
#2

Hi @Willem,

not sure if this is helpful, but if multiple details are on the layout page, you’ll need to enable one of the details to pick something from it. So what about first picking detail, enabling it, then pick the object and once you’ve added your leader just disabling the detail to get back to the page view ?

import Rhino
import rhinoscriptsyntax as rs

def DoSomething():
    
    # get the detail
    detail_id = rs.GetObject("Select Detail", 32768, True, False)
    if not detail_id: return
    
    # enable detail
    detail_obj = rs.coercerhinoobject(detail_id, True, True)
    detail_obj.IsActive = True
    
    # pick object in detail
    id = rs.GetObject("Pick object", 0, False, False)
    if not id: return
    
    # TODO / read user data or do something with picked object
    
    # disable detail
    detail_obj.IsActive = False
    
DoSomething()

Or do you want to pick object inside the detail without having it activated ?

just to answer my own question, i guess this would do it to get the object without activated detail:

import Rhino
import rhinoscriptsyntax as rs
    
def DoSomething():
    
    gp = Rhino.Input.Custom.GetPoint()
    gp.SetCommandPrompt("Pick point on object")
    get_rc = gp.Get()
    if gp.CommandResult() != Rhino.Commands.Result.Success:
        return
    
    objref = gp.PointOnObject()
    if objref: 
        rs.SelectObject(objref.ObjectId)
    
DoSomething()

c.

Hi Clement,

Thanks for the examples, the last got me on another track:
There is an attribute InactiveDetailPickEnabled for Cutom.GetObject.

Still there is an issue that when picking this way, the objects in the detail will not highlight when the selection menu comes up.
@dale is that something you can help with.

Issue is that a Cutom.GetObject with InactiveDetailPickEnabled set to true, will allow object in a detail to be picked. However when the menu for multiple possible objects comes up, there is no high-lite in the detail:

Yet for objects in s detail there is no high-lite:

-Willem

import Rhino
import rhinoscriptsyntax as rs
import scriptcontext as sc
    

def GetObjectInDetail(message=None):

    sc.doc.Objects.UnselectAll()
    sc.doc.Views.Redraw()

    go = Rhino.Input.Custom.GetObject()
    go.SetCommandPrompt(message)
    
    go.InactiveDetailPickEnabled = True
    
    go.EnableHighlight(True)
    
    
    go.AcceptNothing(True) 
    
    if go.Get()!=Rhino.Input.GetResult.Object: return None
    objref = go.Object(0)
    obj = objref.Object()
    go.Dispose()
    
    obj.Select(True)
    return obj.Id
    

    
GetObjectInDetail('pick object')

Hi @Willem, good find :wink: on my side it seems to show the selection highlight with your script, but it uses the feedback color for it:

…and when i hover over a dimension in the Selection Menu, it is not highlighted at all.

This seems to work in the WIP. Have you tried?


(Willem Derks) #7

Hi Dale,

I did not try in the WIP.

But I just did and there is still no highlighting of objects when the multi-selection box pops up…

Actually it seems there is more to it. The Video below is a regular pick on in layout page (after the move command) I do get a highlite in an active detail, but not in the layout picking the 2 details…odd

Is there anything I can test or do to track this down?

Thanks
-Willem
