How to model a car in autodesk inventor
I want to design a car in autodesk inventor i tried lot of ways i know but i can not create...anyone please help me...!!
This is a very complex project to start with. I have a couple suggestions that might make this less complicated:
1) Begin by gathering information. At some point you are going to need reference info. to base your designs from. Examine pictures, illustrations, wikipedia, manufacturer's websites, even manuals (some show exploded views of complex assemblies.)
2) If possible, find exact or similar models that already exist of components that you want to use in your design. If it is the exact part, it is just a matter of locating it in the assembly; however, if the part is similar but perhaps a different size, you can examine it's modeling technique (if an Inventor model) or use a derive technique to scale the part.
3) Sketch the basic design any way you are comfortable with. I find it most convenient to do a side view of a car in AutoCAD or other 2D CAD with dimensioning, this way you can create appropriate proportions quickly. Once you have the this sketch looking good, you can reference it while modeling. If you already have parts you found, make 2D views of them and use them in the sketch for reference as well. (most cars are designed around chassis and engine components) *Note that you can import pictures into an Inventor sketch, so if the picture is not distorted, you could use that as basic guides for parts--especially if you know some information such as wheelbase or tire dimension, etc.
4) Break down the model into achievable goals. It is very hard to "model a car" from scratch unless you work up to that from base components. At this point you also need to decide how complex of a model you are trying to make. Is this going to be a crash test model where exact material thickness and attention to detail are mandatory, or just something to look good? If you are doing exact analysis on this model, you will probably be looking at drawing each component and fastening it together as the real car would be made (or an appropriate facsimile.) Most likely, you will want to simplify the model significantly for practical reasons (computing power becomes an issue on large assemblies.)
5) Decide what modeling technique is most practical for each component. From what I can see in general, surface modeling is the primary mode for creating most if not all car bodies in CAD. Yes, it can be done as a solid model, but form seems to be more limited to simpler shapes as well as time required to create the model. Mechanical components are usually done as solid models.
6) Start doing something...anything. Try to consider how the part is made and try to model it. If you get stuck, try to rethink other ways to model the part before giving up. Almost everyone has made several attempts at a model (at one time or another) before they were happy with the results. The most complex models have started out from a basic model, so don't be afraid to add detail as you have time/skill to do so. A component might be the basic shape with critical points defined before you go back and add ribs, bolt holes, fillets, etc. Detail is pretty, but it also bogs down the program. If you get the functionality down, then hone the details it will end up nice and not be as frustrating when working on other components.
7) Ask more questions! Once you have some background information and have attempted parts, you will inevitably have more questions, the key is to be specific. There are quite a few talented people around here that are excellent at modeling both surfaces and solids from a variety of source info. If you are having trouble with a specific item, ask how others would do it.
You can take a look to this tutorials, hope they help.
