Well, I like the design of the chair. It looks like it would be comfortable and a fairly easy build.
The model has some issues, however. I suspect a number of them are due to the low precision setting and the fact that Length Snapping was enabled. Also, Profile edges shouldn't be turned on while you're drawing. Those thick lines along with the Units settings make it tough to draw accurately.
Going by scene, here are a few other things I've noticed.
Start Cutting With precision set higher (1/64"), the arm rest length is shown as 27 37/64". This dimension is actually not measuring the overall length of the arm rest. It dimensions out to 27 39/64". Seems like nit picking but I doubt you'd really cut the arm rest to that length on purpose. It might not matter in this model but sometimes being off just alittle on one component can throw off the rest of the model developing cumulative errors.
Also, the curve on the inside of the arm rests shows facets indicating the line segments dividing those faces have been hidden instead of softened. Although the curve will still be made of faces, softening will make that less apparent. If you drew the shape of the arm rest and then used Push/Pull, those edges would have been softened. I'm guessing something was done differently.
The two outer slats for the back rest have some reversed faces and in the same area, an additional curve line that is out of place. I'm curious about how you drew these parts.
Look closely at the ends of the angle legs. There are some unneeded faces at the back end. Again, I'm curious about how you drew these components.
Also, for some reason, these legs are not related components. They are, instead, groups. This means that to fix them, you'll either have to fix each one individually or fix one and then replace the others.
The piece that supports the backrest at arm rest level is missing a couple of faces.
Building Since the components are just copied over, the same problems are present.
Relax The texture you've applied is applied to the outside of the components and not to the faces themselves. This makes it impossible to correct alignment of the grain. If you edit that material and change it so the dimensions are 4" x 4", you'll see that most of the elements in the chair have the grain running the wrong way.
To fix the problem, you should delete the texture from the In model section so that everything is set back to default colors. Then start again with applying textures. Open each component for editing and then apply the texture. If the grain alihgnment is incorrect, select a single face, right click, choose Texture, Position. Rotate on the expanded view of the texture and choose Rotate, 90°.
All of this was meant as constructive. I hope you don't think otherwise. If you want more specific information about any of this, feel free to ask. Also take a little time to peruse the Design forum. I think you'll find some things that might help. Also check out Design. Click. Build. on the Fine Woodworking site. I've done a number of posts there most of which have demo videos linked to them.
Keep plugging away. You're getting the hang of it.
