This is something that has proved extremely difficult for me to figure out, I have the side of the frame drawn and extruded into tubes which was surprisingly the easy part. I need to be able to angle the one side of the frame so that when I mirror it using a plane I have centered in the assembly the front of the frame is 23 inches apart in the front and 24 inches apart in the back while also having a vertical taper or angle of 0.88 degrees. I attached drawings that explains what I'm trying to do a lot better. Should i try going about this process in 3d sketch entirely or should i try doing this in assembly? And then how would I do it in either of those, I've tried my luck in both and couldn't seem to figure it out. Here is my little drawing explanation
How should i create a sprint car frame correctly in inventor?
I can't say this is the correct way to model a whole sprint car, but to your specific problem of a frame you wish to align to multiple constraints, you can leverage some clever angles between work and origin features (see below pictures and Inv. 2022.2 example attached). You should also use the third option for angle constraint, where you get to select a reference vector when things get this specific.
Then all you need after that is to mirror using the XY plane of the assembly, in this example below.
Figure 1: Low points of the frame (you could have other points if needed) constrained (mated) to half the total frame distance/span in relation to the assembly's XY plane.
Figure 2: Axis of the frame PART constrained to similar axis on the ASSEMBLY, using a reference vector that suits us for the angle.
P.S.: I used a part but you could do something similar between subassembly and assembly.
