Creating a Drawing for Sheetmetal parts
Once your part is complete, create a drawing for your part (.idw).
Drawing Requirements: (use the FIRST/Robotics drawing template under the English tab on the template menu).
Fill in the Title Block
- Title - this should be exactly the same as the filename
- Current Date - this needs to be updated everytime a drawing is submitted to get parts made (this acts as the revision control)
- Name of student who created the drawing
- Material Requirements: material and thickness
- Quantity required
Drawing/Dimensioning
- Show main views of the part (front, side, top, iso view)
- Dimension the part with the following:
-> overall length, width, and height
-> threaded hole sizes and quantities
-> diameter of holes
-> dimensions of major features
-> if there are multiple features with the same dimension use the conotation 4 X to indicate 4 places.
-> *** if the part is a sheetmetal part that is bent, then the dimensions must also include the dimension to the bends and the radius used to bend the part
(should be .032)
- Indicate if any hardware needs to be installed and on which surface (such as standoffs or inserts - PEMS)
- Indicate any weldments
Saving the Drawing:
1. Once the drawing is complete, go to Save a Copy ---> Save a Copy As "AutoCAD DWG Files.dwg"
2. To the left of the "Save" button click "Options"
3. Once in the "Options" menu click the drop down menu called "File Verson"
4. Select AutoCAD 2000/LT2000 Drawing
5. Without changing any other settings click "Next" then "Finish" and you are all set
Also create a .pdf of the drawing.
Things to Rememeber:
If the part will be welded, then care must be taken to design with the proper dimensioning scheme leaving room for the weldments.
