Well, let’s put it this way, would you understand an idea that was presented with a text description only? Remember a picture is worth a thousand words. Videos, photos, CAD drawings, presentations or if you have no skills, draw it the best you can on paper then scan it and upload it to us. We can except jpg, png, gif, pdf, mp3, mp4, mpg, wmv. The total size of all attachment uploads can’t exceed 10MB.

Are drawings necessary?
