surface model of motorcycle fairing

[Averie]

Help!! I am a student studying surface modeling.My project is to create a surface model of a motorcycle fairing with a windshield and then create an assembly drawing of the two parts. Can anyone suggestwhat approach would best create these models for a beginner - boundary blend, sweep, etc.??

ha. We do this all the time in our one week surfacing class. my faverite thing to do! since we part road racers in the office for the winter.

Basic advice... don't use 3 part boundaries. those are for novice folks. Secondly think over build then trim back to get the shape you want. Thirdly use top down design to split the two parts (at the plastic screws) fourthly, focus your attention onto light reflections.

we have a tutorial called the hood scoop that illustrates this building technique for the faring. I should also state that it is so easy to get bad habits with respect to surfacing techniques. At the same time however it is the best way to add $10 USD to your hourly rate.

Thanks for the reply! I am new to Pro/E and the forum, so bare with me.As a technical college student this is part of my curriculum, so I have only been introduced to the basicsof Pro/E, but I am very interested to learn more. Iam considering pursuing more intense training, like surface modeling classes. Do you or anyone else have a similar model that I could look at to see how thissurface modelwould be created? If you would not use three part boundaries, what would you use? I could use all the help I can get!!!


Thanks - Av

Averie, I do a lot of detailed surfacing. The best advice I can give you for this piece is firstly to picture the piece with the surface meshed, that is with curves that would give you the general sections of the piece. see image below. (forgive my shaky hands, i've been rock climbing all day and it hurts even to type!!!)

Aim on getting as close to the main surfaces as possible, dont mind the outter profile too much just yet as this can come later however try and make sure that your inital surfaces are a bit bigger than needed for now. I dont know how accurate you are trying to be on this, have you some dimensional details on the fairing or is it just purely a surfacing excerise?? Thats up to you, if it has to be as accurate as you can get then be aware of the size now and make sure that your curves do overlap slightly.


Don't be too worried about localised features, like the slight bulge for the light opening, these features will come later. For now just get the feel of creating your sections and then getting some boundary blends in there. We could give you a starting part on how to start off but its important for you to have a go yourself and work from there. Even the lip between the glass part and the lower panel can be omitted now, those details can be added further down the line, or the modeling strategy can be changed later.


At this point just get used to creating the section curves (the mesh of the surface). Work on using the spline feature, how a spline operates itself is key to understaing surfaces, moving a point on a spline affects the curvature further down the line than you might think sometimes.


Its important though not to get too overwhelmed, just take it step by step.


When you feel that you have either hit the wall and cant get any further of have completed as best you can the main surfaces then uplaod the part and we can all advise on where to go from there, and offer some tips that you will at least understand at that point.

Four part boundaries. Then trim trim trim.

Notice that the model is more square at the bottom and more round at the top. I tried to do this w/o the interactive surfacing extension.

I thought this would be a good one for our surfacing class so I took the hour to bust this one out.

ok here is a better picture and the zip file for you. I added this model to our proe training for surfacing section but thought you guys would like the model.
