Modelling an IBM-5100


There is little shading issues but will fix that when the actual rough shape of the model finishes.

Also I have no idea about how to make the back ports because topology is not suitable for that but I’m sure I’ll figure it out : P

So far it’s going pretty good. I decided not to make the exact same model; mine will be slightly modified.

There is a big problem I made two separate pieces; Instrument panel and the Computer it self, idk how to combine them together also vertex snapping doesn’t work :frowning:


Also screen it self not fitting with the computers chase.

Hey, hi there!

Funny that there aren’t any responses to this yet…

So overall, I think you have a good start! Are you modelling this with the subsurf modifier? I use it on just about everything I model.

For the back ports, I’d add in loop cuts vertically and horizontally, (back of case view) of where those ports are giving you faces that you can then extrude inward. The details of those ports (the vents and the connectors) aren’t part of the case, so they can be separate mesh objects.

For the front of the case, your 2nd post shows you have an angled surface where the panel should be. I would have duplicated that area and separated it into its own mesh object. Then modeled the parts for it.

Looks like you modeled the face and all the parts with the face being straight vertically, not slanted like the case is. With what you have, you’ll need to rotate the front panel in the side view and align it the best you can to the case. When you do this, it will to too short, so it will need to be scaled. Rotate in object mode, set 3d manipulator to local and enable scaling should give you a handle to scale in the direction you want.

Next time around, post up a few wire views so we can see the topology. Basically, edit mode pictures.

Keep at it!

Hi! thank you for your awesome response : P

Nope I don’t have a big experience with subsurf modifier I generally use bevel.

Here’s my current topo:



I know it’s not awesome but trying to get a nice topology
Also here’s my screen topo:

My problem is that I decided to model with a flat plane because the topology on the cases own screen was a bit problematic : P modelling the screen with the plane allowed me to model the screen much more easily, but then when it came to how I would join the two pieces together, I was a bit stuck as you can see.

I need to figure this out, and thank you for your response make my morale to go up!

I think I solved the problem.

see?


Got weird (not very noticeable) shading issues near the screen tho.

For more clear topology view:

İdk how to fix them.

Came back here to mention how I would handle the faceplate. I see you’ve done some work and I should have returned sooner.

So you have a faceplate modeled vertically and a slanted computer case to match it up to.


First thing to do is make sure rotation and scale are applied (Object mode - Ctrl-A → Apply Rotation and Scale). Then with the manipulator set to Local, and working for Rotation & Scale, you can click on the red circle to rotate it to match the slant of the case. You can also hit the R-key to rotate it as well, doesn’t matter. Once the rotation is right, then if you need to scale it to fit the case, click on the blue square and drag it to scale the object. When moving/rotating/scaling holding down the Shift-key will give you more precise control over what you are doing.

Looking up this computer and looking at pictures of it, looks like the faceplate should be angled how the computer case is. Your model looks like the faceplate isn’t rotated enough and there is an indentation at the bottom.

A good habit to get into is saving files incrementally. Basically as you hit points in your project, you save it with an incremental file name. Model the basic computer case, save as ‘computer_1’. Add in the vents and refine the case, save as ‘computer_2’. Model faceplate, save as ‘computer_3’. and so on…

Look forward to seeing more!

Opinions on the first question

Take advantage of Latice. It’s easy to control when flattened.

Opinions on the second question
Clearly, there seems to be a problem, not sure where the problem is.

It seems to be solved using Smooth by Angle and Weighted Normal.

It actually solved the problem thanks! (second opinion of yours)

Thank you for your reply It doesn’t matters by the way, I appreciate your help.

For my fix I just inset the face and make a rectangular out of it;



I didn’t do it exactly like that btw I just took the value of the vertex point and entered it into the other vertex point so they became equalized (also this created bad shading issues :frowning: ). It’s a cheap fix but worked I will going to take care of shading issues when modelling stage done.

And thank you for your suggestion I will use this when I’m going to make a remake model of IBM-5100.

Also I just use one file and when I’m going to do a big change I just copy the object and hide it.

I’m going to model keyboard probably the harderst parts oh and model is looking like this at the point;

Thank you for your time and response <3

Well something very very bad happened…

I just broke one of the air gap lines on this side

It should be like this

I do have a backup for my models luckily but that means so much work has gone…

Lmao also that means I can try @revolt_randy’s fix life is funny.

I somehow fixed it without remaking the entire thing : D

There is nothing to do…

I made a stupid mistake at the very beginning of the model. The computer frame is crooked. I can’t fix it because that will break screen to that means I have to restart again…

( At least I can do it better this time there is no need to be sad about a model It’s about the experience you got. )

It’s actually looking better in your latest images, well all execept for it’s unevenness. You could probably fix this, but maybe starting over with the knowledge and experience you’ve gained will result in a better model.

Couple of tips, 1st looks like you are in perspective view, numpad-5 changes it to orthographic view. In orthographic view, when viewing front/top/side views, you’ll have the grid visible. Helps with alignment of parts. Of course, which view is better, is a matter of personal preference.

2nd thing is I just noticed you are not working with the mirror modifier and you need to be using it. With it, you only have to model half of the thing, the mirror modifier will create the other half for you. So in your case, start with a cube and from the front view add in a loop cut at the center. Delete all verts on one side of the cube and add the mirror modifier. Now proceed the create the case, modelling all parts that are symmetrical. Once that is done, (incrementally save the file :slight_smile: ), and apply the mirror modifier and that will make the other half real. Then you can do the non-symmetrical parts, like the indentation for the keyboard.

2 things on the mirror modifier - enable ‘clipping’ - this will make it so when you move verts to the center, they will stick there. Without it, you can overshoot the center point giving you overlapping faces. Other thing is to the right of the name of the modifier you’ll see 4 icons, 3 are enabled. Enable the upside down triangle icon and that will enable the modifier to work in edit mode displaying the verts on the ‘fake’ side of the model.

Hope these tips help,
Randy

I’m so much happy because I made mistakes and I have people willing to help me with my problems. Helping someone is a very kind gesture, Thank you both.

I could have cut my model in half and applied a mirror modifier. But I selected starting from over because I have much better understatement of topology. Thank you for your tips ohh also I’m now modelling it with real life dimensions
