Drafting Cosmetic Edges II - Fantastic Plastic 17 - SOLIDWORKS Tutorial

Claus, Thanks for the response. We are glad that these have been helpful to you. By "a straight line", you have to visualize that before the draft all of those edges are on a single plane perpendicular to the draft plane. Those edges could be coincident to an adjacent part, but are most likely a consistent gaps distance away from adjacent parts. Using "parting line draft", the edges won't move. The draft starts at those edges. Any coincidence or gap between this part and an adjacent part is maintained. When viewed from the side, those edges will still be in line with one another exactly as they were before the draft was applied. Had a "Neutral plane" draft been applied instead, the edge closest to the neutral plane would translate a little, with edges further and further from the neutral plane translate more and more. The edges are now on a plane at an angle to the draft plane (not perpendicular), making them appear to jog when viewed from the side. Any coincidence or gap relative to an adjacent part grows as part geometry gets further from the neutral plane. Great question! I hope that the above makes things clearer for you. If things still aren't clear, we suggest making a quick model and testing out the difference between drafting from a "parting line" and "neutral plane" for yourself. In your tests, use a higher draft angle to exaggerate the effect to make it really clear what the difference is.

Ah! I understand :) Thanks for the explanation. I think the comparison to that "regular" method would have made the video clearer, for me at least.

I absolutely love all the videos in this series. They are very helpful and raised my knowledge on SW a lot. But I couldn't quite understand what the intent was in this one. I can't really see a difference or what you meant by maintaining a straight line. So I have no idea why you drafted those edges, even though you tried explaining in the video.
