How to Submit Parts

    In order to get parts made a drawing must be completed and the appropriate files must be submitted (see below for drawing and file requirements).  Please create a new line in the table FILES TO BE MADE for each part request and email the proper drawing and required files to aaverill@harris.com.  Any questions, please ask Amy Averill.

SAMPLE DRAWING

'Additional' File 'Requirements:'  Besides the drawing there are additional files that need to be created in order to store the actual data of the part.  Determine if your part is a machined part or cut part and then create the necessary file as listed below. 

                  - If the part is a machined part (think parts made from blocks of aluminum with intricate surfaces) then a .stp file needs to be created

                             To create a .stp

                             - Have the part model open (.ipt), go to Save a Copy ---> Save a Copy As ---> Choose file format .stp 

                 - If the part is a cut part (think flat parts with holes, bar stock to be cut to length, sheetmetal that gets bent) then a .dxf  file needs to be created.  The .dxf

                   is basically a stripped down version of the drawing.

                             To create a .dxf

                             *  If the part is bent start by changing the model (.ipt) to the flat pattern (unbent version) before creating the new drawing (.idw).  When the top

                              view is shown it should be in the unbent state

                             - Create a new drawing (.idw) for the part.  Show the top view of the part (with all the cutouts, holes, if there are any)

                             - There should be NO borders or templates

                             - There should be no dimensions

                             - Scale the part 1:1

                             - Then use Save a Copy---> Save a Copy As and save as a .dxf Autocad LT.

Here's an example of how a SHEET METAL should be sent. It needs two views (folded and flat). The flat view should be clear of everything (template, text, deimensions) while the folded view has all the dimensions needed.

This includes:

• Overall Dimensions (L, W, H)
• (For bends) the inner radius and degrees of the bend
• the length of bends (from the center of the bend to the outer edge of the bent section)
• properly annotated holes (the example doesn't have a thread and cuts all the way through, so is expressed as a diameter)
• Thickness and type of metal used (as a note)
• To keep the drawing clear, write notes on repeated parts (example has 4 of the same bends, and therefore has a note)
