creating a coordinate system with weblink

Hi there,

 

is there a way to create a coordinate system with weblink?

I tried it with an UDF, but for some reason I have to select its reference everytime. Another disadvantage I see with UDFs is, that I have to administer two different data-sources for one function.

 

function create_csys_from_udf(reference_name, name_def, trans_x, trans_y, trans_z, rot_x, rot_y, rot_z){

 

var udf_instructions = pfcCreate ("pfcUDFCustomCreateInstructions").Create ("wl_add_cs_w_dtms");

udf_instructions.DimDisplayType = pfcCreate ("pfcUDFDimensionDisplayType").UDFDISPLAY_BLANK;

 

var origin_of_csys = CurModel.GetItemByName(pfcCreate("pfcModelItemType").ITEM_COORD_SYS, reference_name);

 

var selected_origin_of_csys = pfcCreate("MpfcSelect").CreateModelItemSelection(origin_of_csys, void null);

 

var origin_ref = pfcCreate("pfcUDFReference").Create("Ursprung", selected_origin_of_csys );

 

var udf_references = pfcCreate("pfcUDFReferences");

 

udf_references.Append(origin_ref);

 

 

udf_instructions.References = udf_references; --> this is ignored by creo

 

// move and rotate csys

 

var udf_dimensions = pfcCreate ("pfcUDFVariantValues");

 

var translation_x = pfcCreate ("pfcUDFVariantDimension").Create ("trans_x", trans_x);

udf_dimensions.Append(translation_x);

 

 

 

udf_instructions.VariantValues = udf_dimensions;

 

var udf_group = CurModel.CreateUDFGroup(udf_instructions);

 

 

// rename udf-components

 

var udf_csys = CurModel.GetItemByName(pfcCreate("pfcModelItemType").ITEM_COORD_SYS, "CS_UDF_TEMP");

udf_csys.SetName("CS_" + name_def);

 

 

return (udf_group);

 

 

}

 

Any idea?

 

Cheers

 

Mat

Hey Jun,

I solved this problem by using UDFs.

To my application:

I am using a raytrace program for creating and simulating of optical systems (www.zemax.com).

All positions of interesting optical surfaces are exported in a text file, which looks like this:

! 20.06.2013 automatically generated by Zemax

! Generated from Zemax-file: lens.zmx

SRF_0_object,0.0000000000,0.0000000000,0.0000000000,0.0000000000,0.0000000000,0.0000000000

SRF_1_lens1,0.0000000000,-6.2330778704,5.7267826174,30.0000000000,0.0000000000,0.0000000000

...

Creo reads this text file and creates named CS and datum planes for each element.

It is definitely faster than using UI with "create CS from file".

Here is the javascript, that creates the CS:

function create_csys_from_file(reference_name, name_def, trans_x, trans_y, trans_z, rot_x, rot_y, rot_z){


    


        


//    convert text to numbers


    


    trans_x = parseFloat(trans_x);


    trans_y = parseFloat(trans_y);


    trans_z = parseFloat(trans_z);


    


    rot_x = parseFloat(rot_x);


    rot_y = parseFloat(rot_y);


    rot_z = parseFloat(rot_z);


    


//    crop angles greater than 360 degrees




    rot_x = rot_x % 360;


    rot_y = rot_y % 360;


    rot_z = rot_z % 360;


    


//  crop long names  


    name_def = name_def.slice(0, 20);


    reference_name = reference_name.slice(0, 20);


    


// save user's current config setting 


    var udf_path_temp = oSession.GetConfigOptionValues("pro_group_dir");


    


    oSession.SetConfigOption("pro_group_dir", <path, where your UDFs are. Like "z:\\libraries\\UDFs\\"> );




    


    var udf_instructions = pfcCreate ("pfcUDFCustomCreateInstructions").Create ("wl_add_cs_w_dtms"); // name of UDF is wl_add_cs_w_dtms


    udf_instructions.DimDisplayType = pfcCreate ("pfcUDFDimensionDisplayType").UDFDISPLAY_BLANK;


    


    try {




        var origin_of_csys = CurModel.GetItemByName(pfcCreate("pfcModelItemType").ITEM_COORD_SYS, reference_name);




        var selected_origin_of_csys = pfcCreate("MpfcSelect").CreateModelItemSelection(origin_of_csys, void null);




        var origin_ref = pfcCreate("pfcUDFReference").Create("UDF_REF_SYS", selected_origin_of_csys );


        


        var udf_references = pfcCreate("pfcUDFReferences");


        


        udf_references.Append(origin_ref);


        


        udf_instructions.References = udf_references;


    }


    catch(er)


    {


        alert("An error occured:\n" + "reference_name: " + reference_name + "\n" + er);


        return;


    }


    


    


    


//    move and rotate coordinate system


    


    var udf_dimensions = pfcCreate ("pfcUDFVariantValues");


    


    var translation_x = pfcCreate ("pfcUDFVariantDimension").Create ("trans_x", trans_x);


    udf_dimensions.Append(translation_x);


    


    var translation_y = pfcCreate ("pfcUDFVariantDimension").Create ("trans_y", trans_y);


    udf_dimensions.Append(translation_y);


    


    var translation_z = pfcCreate ("pfcUDFVariantDimension").Create ("trans_z", trans_z);


    udf_dimensions.Append(translation_z);


    


    var rotation_x = pfcCreate ("pfcUDFVariantDimension").Create ("rot_x", rot_x);


    udf_dimensions.Append(rotation_x);


    


    var rotation_y = pfcCreate ("pfcUDFVariantDimension").Create ("rot_y", rot_y);


    udf_dimensions.Append(rotation_y);




    var rotation_z = pfcCreate ("pfcUDFVariantDimension").Create ("rot_z", rot_z);


    udf_dimensions.Append(rotation_z);


    


    udf_instructions.VariantValues = udf_dimensions;


    


    


    var udf_group = CurModel.CreateUDFGroup(udf_instructions);


    


    


//    rename UDF - components


    try{


                var udf_csys = CurModel.GetItemByName(pfcCreate("pfcModelItemType").ITEM_COORD_SYS, "CS_UDF_TEMP");


                udf_csys.SetName("CS_" + name_def);


                


                var udf_dtm_xy = CurModel.GetItemByName(pfcCreate("pfcModelItemType").ITEM_FEATURE, "DTM_UDF_TEMP_XY");


                udf_dtm_xy.SetName("DTM_" + name_def + "_XY");

In the meantime, I tried to create that coordinate system directly.

But I did not come too far:

function create_csys(reference_name, name_def, trans_x, trans_y, trans_z, rot_x, rot_y, rot_z){
 
 var feat_type = pfcCreate("pfcFeatureType").FEATTYPE_COORD_SYS;
 
 var features = new pfcCreate("pfcFeatures");
 
// var new_feat = pfcCreate("pfcFeatureCreateInstructions").GetType(feat_type);
 
 var csys_dimensioncontraints = new pfcCreate("pfcDatumCsysDimensionConstraints");
 
 var csys_offset_type = new pfcCreate("pfcDatumCsysOffsetType").DTMCSYS_OFFSET_CARTESIAN;
 
 var csys_origin_contraints = new pfcCreate("pfcDatumCsysOriginConstraints");
 
 var csys_origin = CurModel.GetItemByName(pfcCreate("pfcModelItemType").ITEM_COORD_SYS, reference_name);
 var select_csys_origin = pfcCreate("MpfcSelect").CreateModelItemSelection(csys_origin, void null);
 var csys_origin_contraint = pfcCreate("pfcDatumCsysOriginConstraint").Create(select_csys_origin);
 
 csys_origin_contraints.Append(csys_origin_contraint);
}

Still looking for a method like solid.CreateFeature(instructions).

Hello, Mat again

Have you already solve this problem?

I applied the code you wrote to my Creo, then it works.

(dont have to select its reference)

which version of Creo/ProE do you use?

weblink can't insert feature directly.

API reference says "pfcSolid.CreateFeature is Not implemented in the current release".

and unfortunately, PTC won't enhance pfcAPI including weblink any more.

So the only way you can insert the feature is UDF(or using macro)
