Etabs Api-Python cEdit class

[Raqueeb]

Hello Everyone:
In the auto generated python file in the comtypes folder connected to Etabs.dll there are various classes like EditFrame, EditPoint etc.. I am trying to write a code for EditPoint.ChangeCoordinates and EditFrame.DivideAtDistance but i am not able to execute it. I am getting a return value of -99 instead of 0. And there is no document on these classes in .chm file. Can any one please give a sample of an executable code..

Hi Raqueeb

Sorry for not getting back sooner, just had a look and doesn't look like there is anything under EditPoint or EditGeneral. Let me have a better look tomorrow morning and see if I can come up with something. I think the SapModel.EditGeneral.Move() may work but will need a selected member. Are you selecting the point through the interface or are you working in the background just relying on knowing a Point Unuique number. Likewise, a user function could be written for Divide at distance. I wrote this one a few years back, think it works for columns

def subdivide_frame_insert_yloc(SapModel,frame_name,insert_y):
    """
    params frame_name,insert_y
    return None
    """
    (frame_pt0,frame_pt1,ret)=SapModel.FrameObj.GetPoints(frame_name);
    (x0,y0,z0,ret)=SapModel.PointObj.GetCoordCartesian(frame_pt0);
    (x1,y1,z1,ret)=SapModel.PointObj.GetCoordCartesian(frame_pt1);
    frame_ln=((x1-x0)**2+(y1-y0)**2+(z1-z0)**2)**0.5;
    insert_rat=(insert_y-y0)/(y1-y0);
    if(insert_rat>=1):
        print('Insert point outside member');
        return None;
    x2=round(insert_rat*(x1-x0)+x0,1);
    y2=round(insert_rat*(y1-y0)+y0,1);
    z2=round(insert_rat*(z1-z0)+z0,1);
    frame_section=SapModel.FrameObj.GetSection(frame_name)[0];
    frame_grps=SapModel.FrameObj.GetGroupAssign(frame_name);
    frame_mods=SapModel.FrameObj.GetModifiers(frame_name);
    frame_local=SapModel.FrameObj.GetLocalAxes(frame_name);
    SapModel.FrameObj.Delete(frame_name);
    new_point=SapModel.PointObj.AddCartesian(x2,y2,z2);
    new_frame_1=SapModel.FrameObj.AddByPoint(frame_pt0,new_point[0]);
    SapModel.FrameObj.SetSection(new_frame_1[0],frame_section);
    for i in range(len(frame_grps[1])):
        if(frame_grps[1][i]!='All'):
            SapModel.FrameObj.SetGroupAssign(new_frame_1[0],frame_grps[1][i]);
    SapModel.FrameObj.SetModifiers(new_frame_1[0],frame_mods[0]);
    SapModel.FrameObj.SetLocalAxes(new_frame_1[0],frame_local[0],frame_local[1]);
    new_frame_2=SapModel.FrameObj.AddByPoint(new_point[0],frame_pt1);
    SapModel.FrameObj.SetSection(new_frame_2[0],frame_section);
    for i in range(len(frame_grps[1])):
        if(frame_grps[1][i]!='All'):
            SapModel.FrameObj.SetGroupAssign(new_frame_2[0],frame_grps[1][i]);
    SapModel.FrameObj.SetModifiers(new_frame_2[0],frame_mods[0]);
    SapModel.FrameObj.SetLocalAxes(new_frame_2[0],frame_local[0],frame_local[1]);
    SapModel.View.RefreshView(True);
    return None

Hi Daniel,

Thanks for the reply, I do understand that you would be busy, sorry for troubling you. But thanks again.

I am selecting the points through the interface and using GetSelected function.

In the python generated ctypes file there is EditPoint class, which has few functions as given below, but there is no information in the .chm file, likewise there are many such functions in the generated python file for which we dont have any information in .chm file. like for example cSectionCut.

class cEditPoint(comtypes.gen._00020430_0000_0000_C000_000000000046_0_2_0.IDispatch):
_case_insensitive_ = True
_iid_ = GUID('{67761402-B408-4B43-A72E-4A434C5EAE78}')
_idlflags_ = ['dual', 'oleautomation']
cEditPoint._methods_ = [
COMMETHOD([dispid(1)], HRESULT, 'Align',
( ['in'], c_int, 'MyType' ),
( ['in'], c_double, 'Ordinate' ),
( ['in', 'out'], POINTER(c_int), 'NumberPoints' ),
( ['in', 'out'], POINTER(_midlSAFEARRAY(BSTR)), 'PointName' ),
( ['out', 'retval'], POINTER(c_int), 'pRetVal' )),
COMMETHOD([dispid(2)], HRESULT, 'ChangeCoordinates',
( ['in'], BSTR, 'Name' ),
( ['in'], c_double, 'X' ),
( ['in'], c_double, 'Y' ),
( ['in'], c_double, 'Z' ),
( ['out', 'retval'], POINTER(c_int), 'pRetVal' )),
COMMETHOD([dispid(3)], HRESULT, 'ChangeCoordinates_1',
( ['in'], BSTR, 'Name' ),
( ['in'], c_double, 'X' ),
( ['in'], c_double, 'Y' ),
( ['in'], c_double, 'Z' ),
( ['in', 'optional'], VARIANT_BOOL, 'NoRefresh', False ),
( ['out', 'retval'], POINTER(c_int), 'pRetVal' )),
COMMETHOD([dispid(4)], HRESULT, 'Connect',
( ['in', 'out'], POINTER(c_int), 'NumberPoints' ),
( ['in', 'out'], POINTER(_midlSAFEARRAY(BSTR)), 'PointName' ),
( ['out', 'retval'], POINTER(c_int), 'pRetVal' )),
COMMETHOD([dispid(5)], HRESULT, 'Disconnect',
( ['in', 'out'], POINTER(c_int), 'NumberPoints' ),
( ['in', 'out'], POINTER(_midlSAFEARRAY(BSTR)), 'PointName' ),
( ['out', 'retval'], POINTER(c_int), 'pRetVal' )),
COMMETHOD([dispid(6)], HRESULT, 'Merge',
( ['in'], c_double, 'MergeTol' ),
( ['in', 'out'], POINTER(c_int), 'NumberPoints' ),
( ['in', 'out'], POINTER(_midlSAFEARRAY(BSTR)), 'PointName' ),
( ['out', 'retval'], POINTER(c_int), 'pRetVal' )),
]

thanks for the code you have shared above.
