I teach my student engineers that the front plane should always be the most detailed face of the part. Hence, I would be in agreement with 'everyone else here'. Sorry...
Would you not make any distinction between a part and a vehicle? How about an assembly of parts?
Can you advise any literature that talks about drafting and modeling conventions?
thank you for your response.
Sitting on the seat should determine which hand... Same as a car..
Did some more research and it looks like the SAE convention states that the forward direction of the vehicle is the x axis and downward is the z axis. Which when translated to solidworks would actually put the vehicle (or a bicycle...) on the Solidworks Top plane.
Either way, i cannot win.....
We all learn that there are 3 ways to do things in the workplace. The right way, the wrong way and the boss's way (Are you really that dumb look is optional)
FWIW, I would model the driver's side of a car or (when sitting on the seat) the left side of the bike as the front view. If I were drawing a CNC mill or lathe, the doors would be the front view.
I would also agree, yet disagree with John above. When ordering parts for a car (U.S.) the right headlight is on the passenger side of the car, but I would not translate that to a 3rd angle projected view...
Anal engineers love this topic.. so, this conversation could go on forever...
To each his own... otherwise.. working with many programs/projects myself,.. each 3D program has different screen orientations per XYZ defaults (and some allow for those to change)...so,...
Per/Part or Assembly,.. each products XYZ's are different per program managment and user preference,..
Some users set a default screen orientation for internal company rules/acceptatnce and export per vendor agreement/cooperation.
For the auto/airplane industry, the default position is per a global assembly coordinate system with the front/nose being the XY and Z being the length of the vehicle. ... and, a secondary orientation of each component can be set localized/oriented per the manufacturing/vendor.
The housing/building industry is more specific to our real world/global coordinates,.. with XY (floor plan) and Z (elevation).
Drawing views/orientations are so easy to change in programs,... so, the XY or YZ or whatever are not a factor imho.
For the bike orientation,.. again, it depends on preference.., for me personally, using SolidWorks defaults, I would place the tires of the bike on the XZ (ground/top) and have the frame on the YZ (right).. and the crank/pedels along the XY (front).. that is, the front tire facing the top/right corner of the screen,.. as if I were getting on the bike.... but/maybe, the front tire facing the top/left corner of the screen.. (horse sadding side)?
Just to throw my two cents in on this topic.
My company designs parts that we sell in halves and give 1 to Customer A and 2nd part to Customer B which they then later place together when the modules meet. The way we always set up our planes is based on feature interaction between the two halves so that the Front Plane is set as the primary mating surface. Just another way of making things work. It honestly is more up to company preference how you do things.
Honestly I'd find uniformity to be the thing to strive for here so regardless of decision the "easiest" although not best way of fixing the planes on existing parts would be to
A. Rename the Planes to match
B. Go into the view orientation in the model and Update the standard views to make a view looking normal to the "newly named front view" as the front view.
This will at least solve the issue during collaboration as everyones models will be oriented the same way regardless of how it was initially made
Just as an additional note on the way I set up my models. The way I set everything up means that all parts only require mate constraints of either Plane coincident to Plane or 2 Surfaces Symmetric about a Plane. All parts are oriented the same direction and the Datum Planes on our drawings directly correlate to the Planes in SolidWorks.
We think of them as separate customers: (assuming you are manufacturing from 3D)
- Our Shop as the customer: For example, our machinists have asked that Datum A be the face of the 3D model that will sit on the milling machine's table. This requires the designer to know which machine the part will be made on - which is a good thing.
- Drawing's consumer as the customer: Drawings can be made to look to whatever you would like to give to the customer.
Learning drafting with pencil & straight edge and teaching myself SolidWorks, I'm unsure if there are proper modeling techniques that make assembly & detailing easier. So after we've all agreed which face of the (car, bike, whatever) should be the front, is it common practice to model all other components of the assembly in the correct orientation that they are assembled? For example, if it is decided that the nose of the car is the front, should the side wall of the tires then be on the right/left plane when modeling the tires? Will modeling in this manner allow parts to be inserted into the assembly in the correct orientation to eliminate the need to rotate before mating? And will this have any effect on creating drawings?
"But everyone else here models with the Front plane being the right side of the bicycle." It really doesn't matter which plane they use in the models. When you create a drawing it matters. If your co-horts are not creating drawings with the front view looking at the front forks-tire? something is wrong. See image. Note: I think my choice would be to select the right plane "logical right plane" if I were laying out the frame. The front wheel would be on the left side. Second when bringing in standard views Top-Front-Right side you would not have to select the left view as your front view. Anton stick to your guns!
I orient parts in the same way I would envision them to be oriented in an assembly. For example, if I am designing a lawnmower engine assembly and I want to design a crankshaft, I will choose the sketch planes on the crankshaft part to allow the crankshaft to be oriented in the way that it would be inserted into the engine crankshaft housing bearings in the assembly - if that makes sense. This of course requires you to determine how you want to orient your assembly first. The reason is when I import parts into an assembly, the parts pop in with the desired orientation already and I don't have to waste time re-orienting the parts for easier mating. Hope this helps.
