As promised, another boxier one with multiple simplified projections. Eyeballing the details, keeping it reduced and not adding every tiny detail yet. Also: Blender to the rescue! :D Since I don't have much stuff, I used the cassette player 3d model from Polyhaven and extracted the orthographic views from that (easy with orthographic view in Blender), then drawing and not checking the perspective until finished. Great practise. And yes, I angled the front button too much (wrongly followed the other line back and the thick edge actually doesn't go all around. I need to stop being so damn impatient ...).

Take the orthos of your chosen object and experiment using plan projection! Try placing your object in different spots relative to the picture plane, and then watch my demos to see a step-by-step walkthrough.
Deadline - submit by Aug 04, 2025 for a chance to be in the critique video!
I realized that there would be too many lines from the corners all over, so I started with the base and then started going up, and the handle was last.
Hi. This is my planned projection assignment. I tried to draw a boot. This was hard because the angles go to a lot of different vanishing points. So, I found two and ran the rest of the lines parallel to the viewer. Not sure if that was the right thing to do lol. But I attached pictures of the boot I drew and page where the boot overlaps with the plan, is the one I did before I watched all the demos. The second one includes the orthos and the planned projection after I followed along with all the demos. This was very interesting and something I never knew existed. I haven't seen anything like this before, but it was challenging and fun!
The right-most box confused me.
In the plan view, the front corner of the box “comes out” of the picture plane. I understand that we project that corner back to the picture plane from the station point so we can get an accurate height line. But does that mean that that projected point is also where the actual front corner of the box will be in the elevation view? It doesn’t seem right to me.
The red set of lines looks more correct to me, but they don’t line up with the back corner of the box. The blue set of lines doesn’t look that correct to me, but they line up with the back corner (see shaded blue). But with the red set of lines it does look like I would be getting that “coming out” effect (see shaded green).
So, does it look wrong to me because there is distortion happening or have I messed up somehow?
Cottage plan projections. I was pretty happy with both. Crossing the picture plane and horizon line creates some fun challenges.
Third attempt using one of the buildings from the Zolly app. This one looks really weird and distorted around the top of the building, and I'm pretty sure its because I put the viewers eye too close to the plan, thus making the vanishing points too close. Still, it was fun to do it traditionally, almost easier than digital honestly.
I think this my be final submission, it took me all day to make this one view. I don't know if it my set-up or the complexity of the subject, but what I do know is that using normal table instead of those artist ones hurt my back.
I'm assuming the reason we use the ortho sticking out the picture plane is to make a wrapped view like this one? It didn't come out as quite imaging it would. I assume this is because I didn't due the Eye-level assignment properly and I should go back to it. Any advice?
Also, I just realize that the deadline was for the 4th and not the 8th. These kind of stuff makes me worry I'm becoming retarded.
I think the reason we draw our ortho sticking right out of the picture plane is so that we have a nice reference point that we can line up our heights from (the part of the object that touches the PP - don't giggle!).
Also, I feel the reason why the image may appear to warp a bit is because the viewer needs to have quite a wide view to fit the entire object within their vision. Take a look at the lines that you draw through the picture plane, and the point where you're having them converge (the location of the viewer) if you look at the angle between the furthest line from this point to the left of the object, and the furthest line from this point to the right of the object, you'll have the angle of your viewers field of view. I recall Marshal saying that if this view approaches or goes past 60 degrees some fun distortion and warping will occur! so you could get less warping by moving this viewers position further back (down on the page) and this will change the marks on the PP such that when you plot them again you'll have less distortion.
and finally, if you wanted your drawing to look more like the ref image you attached, I think your spot on with your assumption that its to do with eye level (or horizon line)! in the reference image the top front part of your vehicle seems to be just below the horizon line, whereas in your projection you've plotted the top front of your vehicle to be just above the horizon line. perhaps if you put the vehicle in a box (both in the reference and the plan-projection) it would help to vizualise how you want to position your vehicle. hope this helps you!
I took notes during the lessons, and made some experiments on simple shapes. I conducted the experiments to further understand how the Plan projection works on simple shapes before moving on to actual objects. However, I got a bit stuck on the experiments, could I have some help please?
Experiment #1: I know that the viewer is where that little stick figure is. However, how would we know how tall the figure is? I tried to draw two projections. However only the top one seem to work. The bottom one couldn't converge to VP properly... Is there some sort of limit to where I can draw the object on the pink line?
Experiment #2: My projections always seem to end up distorted, and then I have to redo almost everything to fix/un-distort it. Are there other limits besides the 60 deg limit to make it not look distorted?
Experiment #3: For the drawing objects off the Picture Plane, is the purpose of the 'extension line' as though we are trying to move the object PLUS the viewer to make the object touch the picture plane?
Thanks!
@Li Ming Lin if I understand your question on experiment #1 correctly, then your viewer should be thought of as being ‘zero’ tall…for one projection the viewer is just a point. Your ‘two viewer ‘heights’ with one projection’ will not work because you are actually just moving the viewer position around on the horizontal plane with respect to the plan view ortho ….in your experiment #1 pic, you have moved the viewer further back not made them shorter/lower down. Every different placement of the viewer position then needs a new projection onto the picture plane including new vanishing points which is why your lower image does not converge.
It is where you choose to place the horizon line with respect to your 3D projection that will determine the vertical angle of the viewer ie looking up vs looking down and everything in between.
Trying to think of a simpler way to explain this but it’s not easy…basically, throw out the idea of viewer height/tallness, instead think of viewer position as a point then how close vs how far and looking up vs looking down….check out @Jhamb post just below, they have some horizon line position experiments.
Hope that helps and apologies if I misunderstood your question

Hopefully this helps you better visualize the 60 degree guideline. You can get very technical with 'lenses,' not necessary for the purpose of learning plan projections in 2 point perspective. I'm sure this stuff will be covered later so don't worry about it too much right now. But yes, if you move your projections outside of the 60 degree cone of vision the result will be more distorted the further it moves towards the outside of the cone.
I had drawn an ortho of IPhone charger brick so tried plan projection of that. I was able to do 3d version where I did not measure or used the plan projection but when I started doing the PP I was stumped. I could not understand how to do the prongs.. I did do PP along with Mr. Marshal. Hope I can get some help.

Hey @Shefali Garg, I attempted this and color-coded the lines I used to help me figure out the prongs. It's the same process as how you projected the boxes, but you may want to use another sheet of transparency paper because the projection lines get confusing. Hope this helps!
I tried several times to get this exercise done correctly and of course admire the polish and nice finished work from some of you, where the paper looks so neat and well presented. This is my best effort so far.
I still don’t understand conceptually where to place the viewer, as well as the point of the right inferior corner of the cast shadow of the roof that touches the picture plane. Marshall did mentioned on the videos that this is related to the 60 degree field of vision, but still I cannot grasp the concept and fully understand it.
Thanks for the challenge and this was quite the lesson on perspective!
Struggled to find interesting objects without curves…but tried this beautiful Quran holder on holiday in Morocco. (Though I seem to have forgotten to take a photo of the holder itself…image is an example from internet).
Main ‘epiphany’ was suddenly understanding and being able to visualize what would happen if I moved the viewer position around and /or the horizon line vertically without having to actually draw it first i.e. the ability to plan ahead depending on what side or angle of view I would want to emphasise. My mind’s eye is finally awake….🧠👁️
I left in the unused horizon line - the picture plane is actually the horizon for the projection….if I’d used this and shifted down the vanishing points then it would be a ‘looking-up, lines go down’ situation
So I did my sharpener, table and brush again. The sharpener I did twice with the viewer at different distances. I also did several boxes stacked on top of each other in different angles. You really have to be careful to not mix up witch vp to use.
I have wanted to know how to do things more accurate and how to know where to put different vps when you have several objects in different angles, so the lessons were great. It made me understand perspective better. Now I actually understand why the perspective change depending on how close you are. But you get limited to quite small drawing since you need to be able to fit everything on the paper as well as the angles you can do without getting a vp way to far away to fit in.
Make a orthos of a building on a paper apart. In my Sketchbook i make the picture plane & lines. I did the floor plan, using vanishing points. i build up using the orthos.
It was great see it become a 2d to 3d drawing.
I did it 2 times, 1 on a piece of paper & later in my Sketchbook.
They are both the same shapes with different dimensions .
I use color pencils on finish 3d shape. Pencil on 2d drawing
I did 2 floor plans, the 1st is on the left. I did not think i did it right.
The right side is my 2nd try, i think i did it right.
The 3d drawing begin with floor plan, using the line on the window as starting point, the line go to vanishing point. Then i build up, use the Height plan.
Inspired by one of Marshall's examples, of a little ortho with a sloped plane, I decided to do my own. I like the orthos on this one because the top and front views are identical. The half cube on the middle of the sloped plane made me think carefully.
The first two times I tried (the ones on the right in my image), the 3D result looked very distorted to me. So, I had to think how to make it less distorted, and what I figured out was that I needed the vanishing points further apart. So to manage this I moved the viewer back. The result of that is the drawing on the left.
This might be a very simple shape, but it helped me experiment a bit more with how this picture plane works. I am really enjoying this.
Hi. This is the subject I plan to use for my final take on this assignment, but before that. Can anybody give me some feedback on the ortho views? Do they seen acceptable? Do I need to start over?
Anything you see can be helpful.
