create a parametric CAD model
in 3D Modeling Design
held by sean
Contest Ended, Winner(s) have been selected.
Description:
I have a 3d model of an upright that was produced using topology optimisation software. The optimised model provided must be used as a guide to create a parametric CAD model.The optimised solution will be provided as a solid works file and
I will require the finished CAD model as a SolidWorks file.
I will also provide the original upright design so that you can use it as a reference when creating the new design
I will need the job done by the 15th of october
Wants:
The new design must follow the contours of the optimised solution so that the mechanical properties of the new design match those of the optimised design. They must be better than those of the original designThe dimensions of the bearing sleeve and the bosses must remain the same. The total mass of the new design must not be less than 3.79 kg.
The new design must be as two parts (bearing sleeve and main body)
It will be made from AISI 4142 steel (bearing sleeve) and 7075-T6 aluminium alloy
Software:
- SolidWorks

#3 Sleeve and mainbody
by CADmate
The Bearing sleeve is 100% done while the Body is 80% done. the outer shape was done you can check on the picture and only the holes is not yet but I can work on it. All parts were fully parametric. you can edit anytime you want. I hope you satisfied on my work. Looking forward to hear from you. Thanks

#4 solid main body
by Albertus Putra
At first, I tried to make a solid body from the original design.
I have to erase all the unnecessary holes, and wrap it in a new surface.

#5 parametric-surface-modelling
by Albertus Putra
I converted the .stl file to .jpg files, and inserted them as a sketch picture.
This way I can sketch lines and arcs according to the optimized design.
For such a complex part like optimized-upright, I can't use the basic-features in SolidWorks, so I decided to use surface-modelling.

#6 parametric-surface-modelling sequel
by Albertus Putra
To keep the file size as small as possible I had to divide the file to 4 parts, but it still can be changed easily (still parametric-design).

#7 parametric-optimized-upright
by Albertus Putra
If you want to open the file attached, you have to download all the "parametric-upright1" files.
The final product has the total mass 3.43 kg,

#8 optimized upright assembly
by Albertus Putra
I also attached .x_t format for light-size and easy transferable files on SW
Please let me know if there are any changes

#10 simple parametric upright_1
by Albertus Putra
This is a simplified version for parametric-upright. It is made by basic features in SW, such as extrude-cut, lofted-cut, and boundary-cut.
The mass is the same as previous one, but the shape is less in details.
If you want, I can give additional-fillets to this model.

Discussion
so, will you pick any-winner?
I'm only accepting entries up until the 15th of October.
Are you taking entries until 9 November as in the project info, or 15 October as in the description?
do you mean total mess is main body + bearing sleeve?
Hi
Nice work however your design is a lot heavier than the original. It should be a simiar weight to be considered optimised. Although it can't weigh any less.
Sean
I,ll submit dwgs within 12 hours
what about solidworks 2014
I need a new model created from the optimised design (not the original design). It must be the same mass and shape as the optimised design so that it has the same mechanical properties
again what about solidworks 2014
Hello. Do you accept the 3D model made in SolidWorks 2014?
As I understand,you have a model(R812 DA0483 A C )then you optimized it in optimized upright1 .And you want 3d model of that optimized design?
Will you upload the original .stl file of "optimized upright1"?
We can work to convert the original file, so it can be used by everyone

It would be useful to know under what kind of manufacturing (metal casting + CNC, CNC or only) the piece will be made
Actually uprights must be designed based on some loads that occur. can you explain Loads applied in each Mount/Stay?
perharps this link can help you provide a solid body for "optimized upright1"
https://grabcad.com/questions/how-do-i-convert-stl-graphics-to-a-solid-model
when it become solid body, it can be converted either .igs or .stp version

So you want to create same model with "R812 DA0483 A C" but new model created in SolidWorks 2013 and must have historical drawing mechanism or featuremanager design tree so we can edit more easily in SolidWorks, so it will be parametric?
Sorry they are the only files I have
Can you Provide .stp file for optimized upright1? My Solidworks is 2012 version so it can't open 2013 version. please convert your file to .stp

Low Cost dental Chair Softgoods Design
The task at hand is to find an economic low cost method to manufacture and upholster adult dental chair soft goods. Quality and life of covering must be robust, 10+ year life. The dental chair soft goods typically consist of three major components; underlying support structure, many times this is a vacuum formed plastic element, the seat foam, and the upholstery itself (see attached photos). Dental chairs are normally divided into two main components; 1) The back structure, 2) The seating structure. Key to this design initiative, should include an alternate way of securing the leather to the underside of the chair. Most chairs currently utilize hundreds of staples to secure the fabric, this poses to problems: 1) High direct labor, 2) No way to easily replace the upholstery covering. We are seeking a new innovative design ideas for new methods of manufacture without using staples or typical snap fittings.
