Making decorative element for interior by Mateusz Pietruszka

In this tutorial I would like to show you process of making decorative element for interior. Effect, I think, is pretty good and this technique combined with another can be used to model more complicated elements. Level of difficulty depends mostly on your knowledge about 3ds Max (you don't have to be pro to be able to achieve final result fast).


At first we have to find reference image. In this case I needed to model object I have had physically in my hands, so using scanner was an obvious choice. After few minutes image was ready. It was too bright to use it, so I had to darken it a little bit in photoshop to get better contrast. Here is a final result: download B-9.jpg image. So after this introduction it is time to open max.


I will be using Generic units, so I prefer you use it as well to avoid mistakes. Just roll out Customize from toolbar, click on Units Setup and check Generic Units. We get to the Top view, as we have view from the top of element (you can use either of viewports but it will be harder to operate camera in perspective then)


Pressing Alt + B opens window called Viewport Background . If you think we will choose file now, you are right. Press Files... and choose B-9.jpg in this case. Then tick Match Bitmap, Display Background, Lock Zoom/Pan - it will allow us to use image as a blueprint.

Press OK. It should look like this:


As you can see in the viewport in this situation grid is rather annoying, so I prefer turning it off (just press G as the Top view selected). Now we get into modeling. First step is to create Cylinder with parameters - radius 7.5 and height 164 with eg. 12 height segments. Place it like shown on the image below. Clone it 3 times. Just hold Shift and move it like shown in picture. It is important to have Gizmo correctly in this place (just create Cylinder from Left view).


Now bending it. Convert one Cylinder to Editable Poly and then use Attach button to attach all these objects in one.


We have them attached. It is time to add Bend modifier from Modifier List. Angle parameter allows us to control value of bending it. As you can see -70.5 does its job. It will disturb somehow our placement, so move it again into correct position (even turn it a little bit to match the reference).


Now, also from Modifier List, choose FDD 3x3x3. Roll it out and click on Control Points. Select middle points and put it higher than others. After doing it, select the others two on the one edge, and put it lower, like on the screenshot. It is necessary to avoid bad collisions in future.


We are ready to clone our model. Like before, hold shift and move it like on the picture. Now we just clone it 5 times just for training (if you want you can clone it 1Â000Â000 times - amount does not matters). Remember to be even though a little bit precise to match the reference. Check Instance - if you would like to change shape or bending value, changing it just in one random element will cause changes in every object.

And as a result of our work, we should get something similar to this:


We have done just one side. It is time to do the second one - very easy and fast method. Select all of the elements and click on the Mirror icon on the command panel.

New windows appeard - just make everything look like on the screenshot below.


We get a little bit confused element, so it is time to put it in some order. Just move it to match the reference. This is what we should get after it:


Main thing is finished. Now we will model something to put in on. I have chosen rather simple shape. Just use Line from Splines section. And try to achive for example this shape:


I use mostly Fillet to get little bends. Just select vertex where you would like to have smooth corner, click on Fillet and insert some value (the higher the smoother corner is) or just simply move arrow pointer on vertex and slide it with left mouse button pressed.

Bigger bends are easier to control with bezier and bezier corner.

After some tweakings with line, we should end up with something similar to this:


Now we have just a spline so it is time to make it real object. It is very simple - just add Extrude modifier from list and enter value as big as you like. It just controls length of element. So we are done with it. It is time to make it fully tillable.


Select all elements in the scene, clone and move it on the right to match excatly the ends of last element. Convert last 2 elements (with red crosses on the screenshot) to editable poly and attach them to themselves. We will use Quick slice (Edit geometry) to cut it fast and without pain. Maximaze the Top view and cut it somewhere where the line on the picture appears (it is end of last element we have created with line). Try to be precise to cut it perpendicular as it is possible.

It will add new vertixes along the cut line.


Now delete everything what is on the right side of the cut (crossed with red lines). Delete also elements from the right - they were there just to help us with matching correct position.

We ended up with open cylinders, so we have to close them. Use Border to select edges and then click on Cap. It will fill the ends.

Done on the one side and for the other side is 99% the same. Copy, cut and cap. This is what we should get:

We have nice, fully tillable decorative element for our interior. It has many polys but you can easy change it just by lowering down segments or sides, thanks to instance copying. Final result after rendering is right here:

Very good, tutorial, nice explanation step by step. But, have you an idea how much polygons use to 1 meter of this molding??? You may use bevel profile in a circle shape joined 4 times instead a cylinder, por example, There are too many things to keep in mind when modelling. Perhaps a simple displacement map may be enough to the real need of detail required. Sorry, I'm a teacher of 3D, and I teach my pupils about save and optimize your models. Your work es terrific, and your explanation very understable. Just a comment, Greets from Argentina

Yeah - displace map is a good idea. But my job was to make model from exact shape I was holding in my hand. Making displace in my case was harder thing than just to model it (I'm not that good in photoshop yet:) ) These tutorials are to show beginners some complicated constructions, how to use simple shapes as cylinder or line to create something a little bit more outstanding. You don't have to use this element in your interior. From this lesson you should get the essence that 3ds max is very powerful tool and you can achive some really nice effects without too much effort. And yes - I know, it has too many polys ;) But if you want to use this element to decorate your interior and you're really running out of polys on your computer you can always make disp map from this model quite easily. Maybe next tutorial from me will be 'how to bake displace map' from this model :)

so good , but is so easy , can you have more model ?
