[Music] if we select an object we can view and change its properties in the properties grid let's look at something simpler than a conveyor to start with by going to right click new basic and choosing a cylinder which is a basic shape primitive currently coming in as a white object on a white background but it's okay we can customize this parametric component by looking at the color property and changing this to be something bolder like say red all of these properties have a description underneath which allows us to identify what they do so for example my radius property allows me to change how wide this cylinder is going to be and i can type in a value here that could be numeric like this 0.4 or it could be in a different unit than the standard i have set up which is meters so for example one foot or a certain number of inches whatever i put in there if i put a unit qualifier it will convert that for me some of these other properties are less explanatory let's have a look at what they do this angle property is going to dictate how much of the cylinder is drawn so i could change this to be 180 degrees and we're only going to get half of our cylinder now and our cone ratio determines if we're drawing a cylinder or a cone or something in between for example a value of 0.5 will have a slight tapering towards that end one end the properties we can see here are the simple properties they're only a small set of the total available properties i can toggle to show all properties with this advanced button just here and i'm met with a huge quantity of different parameters which we can change on our system and these vary from dimensions or physics properties or simple things like does this cast a shadow or not often there's some of these advanced properties which we'll use quite frequently we could search for them in this bar at the top or we could add them to our simple properties list with this add simple properties button now when we go back to our simple properties we can very quickly turn our shadows on and off often we'll want to put in numerical values to set these properties but some objects have these small black control points on them that allow you to click and drag and change certain properties directly with your mouse so a conveyor has a very similar control point at the end and at the start which allows you to change the width and length much more convenient than typing out a value directly the properties on a conveyor will differ from that on the properties on a cylinder with a conveyor we have things like a motor which is driving the belt as it moves and we have different properties for its incline its belt material its side profiles which all can be changed within our properties grid just here if we play the model and we see that loads are being created by this load creator this green box again accessible by going new basic load creator then we can also change properties on on loads as they're moving through our model let's have a look at some of the properties on this box if i want to search for some of the physics properties i could type in things which may exist like mass for example or i could type in a colon that's shift and the semicolon key on your keyboard and search for a category of properties i can now see all accessible physics properties and there's some interesting ones here like gravity enabled let's turn the gravity off and play the model and see that this box just keeps floating in air until it bumps into something else like it's in space or perhaps we could select a box just here and look at its friction material and change this to be frictionless to see it slide off other boxes and off into the distance like it's on ice we can also click on our load creator object and see that we can change how frequently loads are released or double left-hand click to bring up a more convenient menu for changing load generation we can even click on the scene itself so the floor to change properties on the scene for example are loads deleted when they touch the floor for a certain amount of time or what's the ambient lighting which is shown so what's the message here all of the objects within emulate 3d are heavily configurable we can change vast numbers of different properties to make it behave and look however we want in fact the number of properties may we well seem overwhelming we don't expect you to learn all of them off by heart instead by actively searching for property names which you think may exist and reading the descriptions of properties you can work out how to configure different objects to whatever specification you design there's also detailed documentation on different objects and the properties they contain which you can read and search through we hope that by configuring these different objects you can build up a whole model and when you configure an object that you particularly like we can reuse them in the future by generating catalogues which will be our next topic
