How to Create Technical Drawings for Legacy Parts

Despite the prevalence of 3D CAD as manufacturing blueprints, many companies still have thousands of older parts, also known as “legacy parts” which still need to be fabricated for use in maintenance or repair operations and for which they only have 2D drawings. This ebook will walk you through 10 steps to make a technical drawing, with clear instructions for your manufacturer. This ebook also includes a SOLIDWORKS technical drawing template.
