Hi,
I am trying to draw an isometric version of this part from first angle orthographic projections. But I just can't do it

2. Save yourself the headache and create a 3D model then derive the 2D isometric from the model. So much easier.

However, if you insist on doing it in 2D remember you'll need to use the ELLLIPSE command's Isocircle option.

OK...here is my rough approximation, given that no dimensions were provided, of what the object would look like as a 3D model using a standard SE isometric view.

And these 2D views, derived via the FLATSHOT command, basically support my premise.

Hope this helps. Good luck.

3. Thought these two images might be of use. One with and one without hidden lines.

No response? Did you decide to drop the course instead?

I'm terribly sorry for my uber late response but yeah thanks a lot for helping out,
also I managed to pass that course but now Im now taking its prerequisite and our dick of an instructor never really teach us anything, just hands out plates after plates
we're now at making cross sectional views and have a new plate that I need some help on lol

6. So what is the problem? Should be easy to create a cross section using the SECTIONPLANE command. Or, if you want to, you can create the 3D model and cut the section(s) yourself using the Object or the Surface option of the SLICE command. You should learn/practice all options so you have a good understanding of which works best for any given situation.

8. also we have to rotate the figure so the x becomes a vertical cross

You should know how to rotate a 3D model already.
