Hi, you have some basic tools in IMA R19, some better tools you find in R21, and more advanced stuff from R28-R30. Catia V7 (3Dexperience) has a better version of IMA, which comes with a new user interface and tools.

hi, there is tons of way to do that. the simplest one is: you prepare your car SubD + the cutting element (also subD or anything else) and trim them together or better fillet them. as I said, there is many ways, you could also intersect, get curves, generate sweep and the trim/fillets. It depends on the quality/precision and flexibility you want to get.

@@antoniopezzella2174 Wow. Thanks for help. Will surely try it out :)

Hi. While I was making the separation lines, I encountered one problem. I want to perform a cut (for door) but it isn't in one plane. The separation line is both in side view and top view. (For example, the doors of sls amg) What I planned was drawing out the line in side view and using split and computing the intersection surface. Then draw another curve in top view using the intersection and perform another split. (Not sure whether this would work) Is there any better way to do this? Thanks!

​@@risheekaiyar4920 i do not reccomend that way. you better create the cutout surface in 3D instead of curves and then intersect it with the car volume. You can also do this by doing a second Sub-D which has the shape of the cutout you need and intersect it to get the curves you are looking for.

@@antoniopezzella2174 Ohh okay. Will try that. Thanks. I had one more query. All the subdivision surfaces I use symmetry feature on develop the symmetrical surface on the mirror side with the original subdivision surface on the opposite side. But for my car body, when I used symmetry, I got a full body (symmetry on both sides) along with my subdivision surface. Nevertheless I carried on with the full symmetric body and performed splits. But when I try to perform spilt on only one side of a plane (say a duct that is present only on one side of the car) , catia gets confused as to which elements to keep. Should have I gone with the original subdivision surface and performed splits on that or am I making some error? Thanks!

Hi, for this video I was using R26

Hi! XV5 and IMA have both the "visual symmetry" function which visually simmetrize everything you model in realtime along a selected plane.

Hello there, Catia V5 >>> Start menu >>> Shape >>> ICEM Shape Design >>> Visual Symmetry Part Level The Visual Symmetry Part feature offers real-time symmetry. A similar feature is Shape >>> Imagine & Shape >>> IMA-Symmetry This works similarly. If you use Visual Sym Part, Catia automatically adds a new part like "Sym Part ....". To use this, you must be in the assembly section. IMA-Sym automatically adds an element like "Subdivision Symmetry.1" into the same batch. There is no obligation to be in the assembly when using this.

Thank you! this was Catia R26, now I am on R28

Thank you! the version is Catia V5 R28

XV5 is way more advanced than ISD, it is constantly upgraded with new tools from VW group, also is it does not belongs to Dassault, this means there is much more flexibility into development process. Also, its interface is similar to Autodesk alias for better performance, ISD is an old robot.

Any information about the cost of the V5 along with XV5? Awesome stuff by the way :)

Hi Alex, I was for many years a Blender modeler, until I discovered Catia, which is in my opinion the fastest software for sketch modelling. if you export from blender OBJ files, you can import them in Imagine&shape. Icem is good to crete bezier surfaces, unfortunately with it, you cannot create any subdivision surfaces like you would do in blender. Try to learn Imagine&shape and afterwards combine it with GSD and so on.

Thanks for quick response! I have to look into Imagine and shape. I'm currently working on modeling a full car hull for CFD simulations to study different aerodynamic parts like different splitter shapes and I want to be sure to get the shape of the car exactly right. I was having a bit hard time in GSD because in Catia I mostly have experience in making smaller parts and assemblies. I&S looks a lot easier way to go so thank you! Also really nice modelling work in this video!

Hey Dude, check out T-spline for Rhinoceros3D mesh to solid. Also Power Sub-D for The foundry Modo. These plug-in's convert **Closed** mesh based models into CAD models that can then be imported into Inventor, Solidworks and so on. Good luck!!
