ASME DETC requires Type 1 fonts for the Postscript (PS) to Portable Document Format (PDF) conversion. The default LaTeX computer modern fonts are Type 3 fonts, which are bit-mapped. Bit-mapped fonts in PDF are grainy and hard to read. Therefore, the asme2e class uses Postscript Type 1 fonts. The times, mathptm, and pifont packages are part of LaTeX2e New Font Selection Scheme for PostScript fonts (PSNFSS). You can obtain PSFNSS and the Type 1 font descriptions and font metrics from CTAN: http://tug2.cs.umb.edu/ctan/tex-archive/macros/latex/packages/psnfss/ http://tug2.cs.umb.edu/ctan/tex-archive/fonts/psfonts/ If the PSFNSS distribution is too large, download just the http://tug2.cs.umb.edu/ctan/tex-archive/macros/latex/packages/psnfss/psfonts.ins http://tug2.cs.umb.edu/ctan/tex-archive/macros/latex/packages/psnfss/psfonts.dtx files and run % tex psfonts.ins to create the times, mathptm and pifont packages. The associated fonts you can download for these packages are in http://tug2.cs.umb.edu/ctan/tex-archive/fonts/psfonts/adobe/times/ http://tug2.cs.umb.edu/ctan/tex-archive/fonts/psfonts/adobe/helvetic/ http://tug2.cs.umb.edu/ctan/tex-archive/fonts/psfonts/adobe/courier/ http://tug2.cs.umb.edu/ctan/tex-archive/fonts/psfonts/adobe/zapfding/
