Re: How to create Sketch Feature

Hello Friends,

I write a function to create sketch feature , Feature created in feature navigator but 2D Line does not get added in sketch feature , I am sharing the function for your reference . Please resolve the issue.

Your PRO_E_STD_SECTION element of the feature tree is missing the PRO_E_STD_SEC_PLANE_ORIENT_REF element.

Next, in your UserCreateLine function you don't create any reference to the existing geometry. that means that your 0,0 coordinates are not defined and your sketched lines may not be placed in the desired location.

Check your documentation, especially the section called "Element Trees: Sketched Features" in the user guide.

Also there are some good examples in <creo_toolkit_loadpoint>/protk_appls/pt_userguide/ptu_featcreat. Have a look at UgSketchedCurveCreate.c and Ug3DSection.c. Those two file are showing an example of creating a sketched curve.

One last thing. The way you posted the code example makes it really hard to read. For the future I strongly suggest to use indentations to make it more easy to read.

Something like:

if (status != PRO_TK_NO_ERROR)
{
	status = ProSecerrorCount(&section_errors1, &n_sec);
	for (i = 0; i < n_sec; i++)
	{
		status = ProSecerrorMsgGet(section_errors1, i, error_message);
		ProWstringToString(error_message_s, error_message);
		status = ProSecerrorItemGet(section_errors1, i, &error_id);
	}
}

compared to:

status = ProSectionAutodim(*section, &section_errors1);
if (status != PRO_TK_NO_ERROR)
{
status = ProSecerrorCount(&section_errors1, &n_sec);
for (i = 0; i < n_sec; i++)
{
status = ProSecerrorMsgGet(section_errors1, i, error_message);
ProWstringToString(error_message_s, error_message);
status = ProSecerrorItemGet(section_errors1, i, &error_id);
}
}
