Request for the text style to be created automatically during the import when importing .LIN custom linestyles that use a text stylewithin the definition.
Set the following capabilities:CAPABILITY_LINESTYLE_CREATE_STDTXT, (enabled by default)Allows the creation of text style Standard.When importing linestyles from a .LIN file, if the "standard" linestyleis needed, it will be created.CAPAB ILITY_LINESTYLE_CREATE_TEXTSTYLE, (disabled by default)Allows the creation of a text style of any name.When importing line styles, if a named text style is needed, it will becreated.Note:-During the import process, the DWG seed file (not the transeed) will besearched for a text style with the correct name, then use it in thecurrent file as the text style definition. If a matching text stylename is not found, it will create one using fairly common text stylesettings.-When the text style is created this way, the style created for"Standard" will most likely be correct. However other styles createdthis way will most likely not be correct.
