    Software For Automobile Modelling

    You really need G2 continuity with stylized surfaces on Auto interiors and exteriors. What you really require is more control over curves and surfaces. Y=X^3 type curve math available in Solidworks and even older versions of Pro/ENGINEER have to fake (so to speak) G2 or approaching G3 does not allow the control in the light refelections required by the seasoned auto designers. http://jobs.designengine.com/jobs/cad-specialist-2 < these guys use Alias for the difficult surfaces and use Solidworks for engineering. http://jobs.designengine.com/jobs/gmengineer < GM seating Designers can use Alias however UG is capable of higher order math y=x^7 or in Alias speak 7 degree curves.

    Solidworks Boundary Blend

    Okay... first question, what happened to my login. Did the site get hacked and corrupt the database or something. I've had an account here for years and now it's gone. I have a boundary blend that finishes off a solid helical feature in solidworks 2011. Im having a hard time getting the surface to adhere tangentially to the surface and I'ts quite frustrating. I guess I should post a picture but I am not giving up and doing it in Alias or Pro/E! Typing out my problem forces me to think about the problem and come up with a workaround.... I created the blend between the solid face of the helical thread and a sketch curve that is rests on a plane. So one work around is to use convert entities and force a 3d curve tangent to that new curve...

    Clay Bake Challenge

    I am not sure if this part of the forum is closed to one or a few for posting form challenges. if so please promptly delete my post. on another forum I was discussing problem solving techniques and used one software or another as requiring more problem solving workarounds over another and got into more of a bench mark explanation... long story short I explained that when I learn a new tool I force myself to create a forum using specific model practice or techniques in push myself at the tools harder. Right now in our office we are pushing the Rhino tool very hard and struggling some. But for this challenge I suggest the interesting part is to leave it open for any tool. Pro/E, SW, Maya, Rhino, Alias, Catia, Unigraphics.... That way we might get more participation from those who might not have thought to participate. I think this screen shot image is good but maybe an iges file is better? I made a 30 minute list of challenges with respect to Pro/E, Alias, Rhino and Solidworks.... problems workarounds and techniques. ABBREVIATED BENCHMARK COMPLAINTS FOR THESE FOUR TOOLS Pro/E: users utilize the add on package ISDX to use COS to trip back the melted glass. 2 uses parametric combined with free form curves to parametrically control (not calculate) the bake and melt sag. parent child relations aid engineers calculate the bake process parametrically. WF 4.0 allows user to tug and pull on internal CV's of the surface yet while maintaining parent child relations to the original curves. End point constraints can accomplished with the Curve thru Points tool in stock Pro/E however upon redefine of the curve thru points on surface requires loosing the tweak mods before redefining. No Isoparm display on the surface offers no density feedback to designer therefore compared to light geometry that might be created in Alias Studio no isoparm display may create unnecessarily more dense geometry. Warp tool in Pro/E is hard to localize manipulation and might be difficult to manage the hot clay scenario. Alais: - since Curve on Surface cant force tangency on end points in Alias Studio or Auto Studio experts might reach for the common work around alternate technique of using a 3 degree curve not sketched on surface and project instead as a work around. Alias experts like to tug and pull on the internal control verticies of the surface to obtain the weighted hot glass look instead of managing thru curves. Hi end users often brake construction history so they get to rebuild the curves and surfaces instead of making slight mods to make before and after bake or melting games. When modifying and pulling on internal CV of surface user is forced to brake construction history. Full tangency and isparm display. Rhino: user has to constantly rebuild curves and surfaces ... designers are still struggling with the model in our office this week and I have not seen if they can force tangency on COS endpoints. Rhino parent child is maturing and users remodel to obtain the various modes of melted glass. When modifying and pulling on internal CV of surface user is forced to brake construction history. Full tangency and ispparm display. SW: model technique works similar as Pro/E without the add on expense of ISDX but lacks realtime update feedback. SW can't project a 3d curve onto surface so the Alias technique is not possible in SW (2007) but this curve on surface technique works great since in SW users can control end point conditions with curve on surface. As user flexes for modifying the weight of the hot clay scenario before it cures the parent child relations might fail or require a repair. Users can not modify internal CV (maybe they can?) of a surface. 'Fill surface' tool offers unique tools for managing the weight of the hot clay exercise. No tangency line nor isoparm display might cause more complexity when creating cross or internal curves due to not being able to snap directly to the tangency edge. 'Flex input' tool works here for a work around to managing the weight of the clay mods but the tool is difficult to localize and control the tool (2007)

    Lock Dims In Skether

    What's the best way to lock a sketch in a solidworks sketch? I want to flex geometry upwards with a mouse drag whilst keeping all the other dimensions locked too a specific value.
  5. All the big players use Pro/ENGINEER except Ryobi... they use SW .. I guess they are not big players. It is hard to beat the Curve tools of ISDX
  6. When I create a surface boundary with as series of curves forming a four part boundary two of which are the same 3d curve, how can I get solidworks to refrain from consuming those curves once the surface is bundled into Boundary-Surface.

    How To Model This!

    cool stuff. four part boundaries and a texture map. Might tone down the specular highlight some.

    3d Fur Surface

    Maya. Use maya paint effects. Its so cool how you can paint on nurbs surfaces and basicly paint on fur, grass, rust, water, or what ever else you have the mind to paint.
  9. if you want to work at a major manufacture then research what tools they use. Nike Motorola and Bissell all use Pro/ENGINEER. some of the industrial designer might use either alias or Rhino but they all convert at some point to Pro/ENGINEER. I suggest learning Pro/ENGINEER first then one of the inexpensive tools like Rhino later. Your primary mission is to get a job and leverage your strengths to get that job.
  10. in assembly mode... click on the part. Right hold down and release on the 'Activate' option. Now your in the part thru the assembly. Dimensions come up and use regenerate like always.

    Rhino Modeling Help :((

    One fundamental problem with designers and engineers when modeling above the crown of a bottle.... the product cap does not fit the prototype. You develop a concept and go for a prototype. In the presentation meeting you want the production cap to screw onto your SLA right? Don't use a machinery handbook to obtain details about the thread. Go directly to the manufacture and ask them to email you a PDF showing the precise dimensions. Then when you recreate to that drawing you get the production cap to screw on. once 6 years back I developed 20 or so of 100+ bottles. My twenty bottles were the only bottles that caps actually screwed on. Now i teach that type of stuff in my two day plastics part design class... check it out: http://www.proetools.com/courses/plastics/plastics.htm good luck

    Rhino Help Please

    in surface modeling we call that the globing effect. Divergent surfaces all come together into a point like a globe.

    Nissan 350z

    that proe 350z model was built by one of design-engine's four week comprehensive students in a fifth week of working on his own. That is the kind of training design-engine offers designers during a recession. He had a degree from the polytechnic in Milan IT and knew Alias Studio already. http://www.proetools.com/courses/pro_engin...nsive_wkshp.htm

    Nurbs Import To Proe

    I live drink eat and sleep that sh*t. BTW I just got back from boston from a week of WF5.0 beta testing. Pro/E now gots mental ray render engine. IKES..... And some new dope surfacing tools. You can now download that off of ptc.com

    Surfacing: Bike Seat

    By the way ... Pro/ENGINEER now uses Mental Ray with the new Wildfire 5.0 release
  20. I have administered this plastics class maybe five times per year but this week I created these die cast part design workshop and a forging forged part design class. I wonder what it would take to make industrial designers more interested in taking classes such as these... any feedback would be awesome! http://www.proetools.com/courses/plastics/plastics.htm plastic part design workshop http://www.proetools.com/courses/plastics/diecast.htm die cast part design class http://www.proetools.com/courses/plastics/forging.htm forging forged part design class

    Nurbs Import To Proe

    thats funny... I found that if you take some time to explain to an engineer why you are trying to do something that they will go out of their way to learn surfacing. My Why from a design engine perspective: 1. because you make more money 2. because you can't model the form with out surfacing 3. becasue you need to manage light reflections better 4. to make a more robust model using bounding boxes and lattice structure

    Nurbs Import To Proe

    When I teach that class its not about taking IGES or STEP data into Pro/ENGINEER but helping those engineers understand the integrity the id'ers gave the form and (they remodel anyway) helping those teams remodel so they can manage that data. Its not enough now days to just import (punt over) geometry to Engineers. They need to be trained to understand form so they may capture form at a higher level. Once that dumb data is imported I offer multiple technique for capturing that form so the geometry can be managed parametrically. For the surfacing track i teach it starts with the week long surfacing then ends up with the http://www.proetools.com/courses/pro_surfa...nced_import.htm < The numbers are not chronological since this is our level 5 class and should be level 8.

    Solidworks On A Macbook Pro

    If your serious about your work I really doubt you would use a MAC Book Pro for doing your work. Everyone I know who is a mac enthusiast and does Solidworks or Pro/ENGINEER has two machines.
  24. There are different needs with imported data as well. Often with large assemblies I will export the OBJ format because the geometry it produces is lighter. Some parts may need to export as IGES. The mix and match may be necessary. As long as every part imports into the right spot and no scaling is necessary.
