From the "DTM" dialog shown below: Select... LOAD > DTM FEATURE
The Load DTM Features dialog will appear as shown below:
Select TIN from the Load File options, and browse to the TIN file using the Select Files button. Select the TIN file.
Single click on Triangles, and set the appropriate element symbology for the triangles to be drawn.
