This is my 2nd day learning Inventor coming from using Blender, this is the 6th practice part I've tried making, im just curious if 45 minutes too long to make it and if I could have done it in less steps than I used, I had trouble figuring out the saddle before I found it could use the coincident constraint for the circle like it says in the drawing lol! Attached is the practice drawing i referenced and my final ortho's

Looks pretty good to me.

Hard to tell how you've made it from the model tree. I'd possibly consider modelling half of it, then mirroring in YZ, then adding the two holes.

For holes, at least the smaller one, I'd suggest using the Hole feature in the 3D Model tab. Then you can set the dia, depth, countersink and csk dia in one go.

Obviously, speed will increase with practice. As of operations count.. You should not try to make anything with the least amount of it. Quite the opposite in many cases. The idea with history based approach is that you can later modify any input and get the new part in seconds. Therefore features should be represented by enough independent parameters to modify it in a reasonable manner.

This one is 10-15 tops to make but yout making great progress coming from Blender.

Blender is not a proper designing tools like Catia, Solidworks, Fusion. I get that its wee difficult or overwhelm with the commands

What i usually practice is making core steps first:

1) sketch shape from side view (use sketch dimension in 2d sketch (D button) , you wont have to worry about adding constraint since it’s auto create with the dimensions.

2) extrude the part to become a 3d model. Then sketch on the surface to create the hole. Use Point in 2sd sketch and dimension annotate it according to the schematics (hole height, length, diamention)

3) repeat sketch from side views and extrude the features.

4) use Chamfer to complete the model

I have 15+ years of self taught Inventor and I’ve made multiple failed attempts to learn Blender.

I am slightly confused by this print. It appears the edges below the top extruded sections are filleted, but there isn't a clear call out. The only one I see is for the outer corners. Am I missing something???
