Automotive form generation: wheel arches

Automotive form generation: wheel arches


at the end of this lesson you will be able to extrude sketches edit form in certain bridge edges generate a car’s body starting from the wheel arches and we were geometry in order to create the body of the vehicle let’s enter the sculpt environment and turn on the sketches you use for the wheel reference imagery click create extrude and select both sketches pull to create two small cylinders eight faces and one front face is a good configuration then use edit form to bring it to the edge of the canvas the next step is to scale them so that they do not represent the wheels but the outer edge of the wheel arch lip select the edge farthest away from the center of the vehicle and use edit form to scale it down press alt while doing it to create new faces do the same with the rear wheel if you want to add definition to the edge of that wheel arch lip use insert edge and place it close to the edge where you want to highlight after that scale the edge closest to the center of the vehicle to get the fall-off where the wheel arch will meet the rest of the body repeat for the rear wheel after that delete the sets of two faces at the bottom of both of your cylinders use edit form to adjust edges using your canvas as reference you now use bridge to generate geometry to join both of your wheel arches select the edges from the bottom of the wheel arch to the top then use edit form to adjust to your design select the outer edge of the geometry and select edit form use all to scale the edge out while creating new faces and then move the edge closer to the center of your vehicle in order to generate some shoulder in your car body after that adjust the edges to match your design in the campus then again using alt move and scale the outer edge build the window up and adjust again try and make the lines in the topology follow the aesthetic features of your vehicle this will help downstream now that you have the main silhouette of the side of the vehicle use edit for mode pressing alt to create new geometry and bring it to the center of the vehicle beginning with the front then adjust to fit your canvas this workflow helps to keep a topology that follows the aesthetic features of the vehicle do the same with the rear it does not have to be exact at the moment but the more you get it close to the desired outcome the better then repeat the operation with the top of the car pull the points towards the center of your vehicle close to the plane where your side of your canvases then click modify flatten and select direction select plane choose the plane and then select all the vertices and click OK now all of them are aligned on the plane notice how the geometry is not complete use modify weld vertices to fix notice how the form got more round than what the canvas shows don’t worry this happens the form can be refined later however feel free to adjust so that even in this low resolution your vehicle is as close as possible to what you want to get now let’s get the other half of that car body to do this click symmetry mirror duplicate select the t’s plane body the mirror plane and then click ok now let’s work on the top view to continue refining our shape by selecting a face edge or point and using edit form you can use a sub modification option notice how the points graded from red to white as they get further away from your selection you can adjust the gradient to affect more or less area continue refining until you are happy with the result don’t forget to adjust the bottom edges of your vehicle to fit your canvas we just generated the basic form of the vehicle in a very quick way in this case we try to be as faithful as possible with the canvas but feel free to continue generating iterations to explore more options until you find the winner
