Templates in HTML format give you more possibilities for different layout, fonts, and images. Templates that generate output in HTML format are graphical and have the file name extension *.html.rpt.
The Select Attribute dialog box appears prompting you to select an attribute for the value field.
Include the extension *.html.rpt in the file name. For example, Part_list.html.rpt.
If you add images in your HTML template, the images should be located in ..\Program Files\Tekla Structures\<version>\nt\TplEd\bitmaps folder, otherwise they are not shown in the HTML output.
