Creating 3D Scenes and basic 3D editing in ArcGIS Pro

in this video we're going to look at creating a 3d scene and doing some 3d editing in arcgis pro now a big driver for the development of arcgis pro was to have the capability to do things in 2d and 3d in our projects whereas previously in arc desktop that capability had been spread across different applications so now in pro we can do 2d and 3d uh in one application so if we look at this 2d map we've got a single layer called buildings um it's got one polygon if we have a look at the attributes um an additional attribute has been uh created and we're going to use this attribute in a minute it could be called anything we've called it height and it's got a numeric value in there so how would we view things in 3d well we could create a new 3d map or we can convert this 2d map to 3d from the view ribbon so either to a global scene so place it on a globe or to a local scene which is what we're going to do here now when the 3d map opens we've now got a 3d layers and 2d layers groups and we can actually drag layers between those two groups so the map has open and our polygon has now disappeared and that's because it's below the elevation surface we're now doing things in 3d so how would we look at this building layer in 3d well we open the properties and we've got an elevation setting here and if we go to that we've got a drop down and we've got some options so the first option is we can view the layer on the ground so that's on this elevation surface when we're using the default elevation surface we could also have a cartographic offset setting near the bottom here and that's as the name suggests just to make it a bit more prominent in relation to the layers around it alternatively we can look at it relative to the ground so that's relative to this elevation surface and we could either use an attribute an expression or we could base it on the geometry z values so that's basing it on the vertices or we could have these layers at an absolute height so regardless of the elevation surface so that's based on the datum so think of something like um an airplane so uh let's select that one at an absolute height now which value we're going to base it on well we we're going to base it on our height attributes and then if we just okay that so if we just go to the full control option down here in the corner we can actually get the 3d ring and we can actually look at the map in 3d and rotate it and we can see our polygon is now just displayed at our height so we're now operating um in 3d so let's go back to that and let's just put our polygon um back on the ground and just give it a cartographic offset so there it is it's now back on the ground so as we can see so what would we do if we wanted to create a 3d object from this well we could extrude it so we would need to go to the appearance ribbon at the top and here there is an extrusion option and we've got some different options from the drop down all options will give a flat top except base height which is based on each individual vertex so let's select max height for this example and then we've got to decide uh what value we're going to base the extrusion on so we could either enter an expression through the expression builder or we can select an attribute so we can select our height attribute and the object is now extruded based on our height and we get this a building effect and if the data type had been aligned and was extruded we'd get this wall effect or if it was a point you'd get a pole effect with extrusion if we want more options to display our polygon in 3d we'd need to use a multi-patch feature class or a 3d object feature class so to do that we would create a new feature clash just in the normal way through the catalog pane we'd give it a name and then uh once we've done that we've got the data types and as well as the normal data types we've got this multi-patch and 3d object feature class so in this example we're going to use multi-patch and then we'll go on to the next window and we could create attributes but in this case we're just going to select the defaults once that feature class has been created it is then added to our content pane just as you would normally create a feature class so uh i'm just going to change the symbology and just make it orange so just so it's a little bit more prominent before we start editing so to edit we would then go to the edit ribbon go to create as we normally would um if i want to show measurements when we are editing we make sure the dynamic constraints are turned on from this option down here and then we can go to create geometry 3d geometry and then just using mouse clicks we begin to create our polygon so then back to the beginning and a final mouse click and we now have a 2d polygon shape we can now place the cursor over the polygon and we get a green circle and when it turns to red if we hold down the mouse button we can actually just lift the face and create a 3d object and in this way we can actually place the cursor over any surface of the object and move it now we can also go on to the edge we can actually cut an edge so when we go to the middle of the edge it'll actually we'll get a across and we place one mouse click on one edge and one other mouse click on the other edge and now that actually splits the edge into two and once again we can move those surfaces in this case we're just going to go on to the green circle and we're going to lift both surfaces and if we look at that now we've created a ridge we can also even cut out a new surface just by placing mouse clicks in a rectangle here and now we've created another separate surface and we can lift that surface independently so in this way it's very easy to create a 3d shape so having created our 3d shape we want to really probably want to render that to make it look a bit more realistic and so we can we're going to do that so let's just remove the the orange symbology and now we're going to if we want to render it we would go to modify feature and then we've got this multi-patch texture and with this we're able to um we can load a texture and we can use image files and in this case we've got a couple of jpegs which are images of buildings so if we take this building front with all these windows and then we can open that and then it comes into our modify features and we can now just um place a mouse click on one of the faces and it will place that image there and if we go back into the modify features pane we can just use the pan uh and zoom and rotate and actually scale it to get it right for our building and just zoom in and out until it till it looks right so we've done one face there um we can also uh we could use a color and again we just click on one of the faces and we we've just colored that pink so let's take this roof image and again we just mouse click on that face to to place that image there and again now we'll scale it by i'm just using the mouse wheel to scale it to get it realistic click on the back face to put it there so again we're building up this picture you can see how you can symbolize each face individually to create a realistic looking 3d object so we need to save our edits from this edit session now if we want to look at this project in both 2d and 3d let's go to the view ribbon and we can actually move this 3d map and just drag it so that the 2d and 3d maps are alongside each other so we can view both at the same time however both of these maps are independent of each other at the moment although they do share a layer in common but we can actually link both views and we've got this link views option and we can either link them just by location or we can do it include scale as well which is what i've just done so whichever map i'm in the other map is synchronized so they are linked together so again this comes back to the point i made at the start of this video that it's very easy to move between 2d and 3d in your project in arcgis pro so that's a a quick view on creating 3d scenes and some basic 3d editing and i hope you found that useful you
