Hi,

This pycode does not work,can you help me?

import rhinoscriptsyntax as rs

srf = rs.GetObject("select Extrude surface",rs.filter.surface)
if srf:
    cmd = "_ExtrudeSrf _Pause S=_Yes "
    rc = rs.command(cmd + chr(34) + srf + chr(34), True)
    rs.HideObject(srf)
else:
    print "not select surface"

It does not work,please help me.

This is one way:

import rhinoscriptsyntax as rs

srf = rs.GetObject("Select surface to extrude",rs.filter.surface,select=True)
if srf:
    rc = rs.Command("_ExtrudeSrf _Solid=_Yes ", True)
    rs.HideObject(srf)
else:
    print "No surface selected"

Preselect the surface before calling rs.Command()
Pay attention to both indentation as well as capitalization with Python (rs.Command(), not rs.command(), etc.)

Hi Helvetosaur,

It must preselect the surface, can you make to select the surface to extrude at once? Do not select it twice.

Thank you.

4 
srf = rs.GetObject("Select surface to extrude",rs.filter.surface,preselect=True,select=True)

Thank you. It works well.

Hi Helvetosaur,

If I select the surface of the joined solid, could it done?
Now I can only select the single surface,no the surface of joined solid object selected.

You want the extrusion to be selected at the end, is that it? Otherwise, I don’t quite get your question. --Mitch

thanks

Something like the following will allow you to select either a single surface or a polysurface and extrude it, deleting the original.

import rhinoscriptsyntax as rs

msg="Select a surface or polysurface face"
obj_ref=rs.GetObject(msg,8,preselect=True,select=True,subobjects=True)
rs.Command("_ExtrudeSrf _Solid=_Yes _DeleteInput=_Yes", True)

I am very sincerely grateful to you for help me.

If I want to select a curve and a surface, How can I do?

Thanks,
Have a good day!

This gets more sophisticated, as first, there are two separate Rhino commands for extruding curves and surfaces, plus in order to extrude a curve solid, it has to be closed and planar. So you need to separate the two cases curves/surfaces and also filter for closed planar curves.

Two basic ways to do this, one is to accept all curves and then filter after the selection - refusing to do anything if the curve is not closed and planar - or using a more sophisticated technique, prevent the user from picking curves that are not closed and planar with a custom filter in rs.GetObject().

import rhinoscriptsyntax as rs

msg="Select a closed planar curve, surface or polysurface face"
obj_ref=rs.GetObject(msg,4+8,True,True,subobjects=True)
#separate curves and surfaces
obj_ID=obj_ref.ObjectId
if rs.IsCurve(obj_ID):
    if rs.IsCurveClosed(obj_ID) and rs.IsCurvePlanar(obj_ID):
        rs.Command("_ExtrudeCrv _Solid=_Yes", True)
    else:
        print "Unable to extrude, curve is not closed and planar!"
else:
    rs.Command("_ExtrudeSrf _Solid=_Yes _DeleteInput=_Yes", True)

import rhinoscriptsyntax as rs

def cp_crv_filt(rhino_object, geometry, component_index):
    #filter for closed planar curves
    return rs.IsCurvePlanar(geometry) and rs.IsCurveClosed(geometry)

msg="Select a closed planar curve, surface or polysurface face"
obj_ref=rs.GetObject(msg,4+8,True,True,custom_filter=cp_crv_filt,subobjects=True)
#separate curves and surfaces
if rs.IsCurve(obj_ref.ObjectId):
    rs.Command("_ExtrudeCrv _Solid=_Yes", True)
else:
    rs.Command("_ExtrudeSrf _Solid=_Yes _DeleteInput=_Yes", True)

Very Nice!
Thank you very much. I’m going to study hard.This is a good idea.
