0:01 In our final lesson, we’re going to address one last major hurdle that is often cited when I ask what are the challenges to building complex landscapes in 3D…
0:12 What I’m referring here to making changes.
0:17 I’ve often heard and personally experienced the sentiment that it’s easier to start over from scratch when working with landscape and terrain models than it is to make revisions to them.
0:27 And that’s probably true if the model was set up without proper groups and layers.
0:32 Luckily for us, changes should not be a problem as we’ve built this model knowing that it’s not IF revisions are needed, but WHEN.
0:40 That said, let’s make some revisions together now.
0:45 As you can see we’re back in our completed park model with the ‘Working’ scene showing.
0:51 Let’s focus in on the stairs and make the assumption that this extra stadium seating area on the right needs to be removed.
0:59 So that impacts several things: The seating itself that needs to be removed…the cheekwalls extended...and the planting slope will now have a missing piece that needs to be filled in.
1:12 Let’s take it one step at a time and first remove the elements that we no longer want.
1:19 Before deleting anything, it’s probably a good idea to have a back-up saved in the event we need to retrieve anything later.
1:28 So now let’s go into the walls group and select the part, or parts of the wall that we don’t want anymore.
1:38 It’s important to group anything before deleting as it may have shared edges and just deleting it without grouping may remove adjacent those faces along with it.
1:48 Also, instead of deleting, let’s assign this to a new frozen layer as, even with a backup, it may be faster to grab some linework from this frozen layer if needed.
2:01 We can always delete this layer later once we know for sure the revisions are approved and that we won’t need it again.
2:08 And now since our seating was on in the walks group, we’ll have to jump into there in order to repeat the process.
2:16 First select…then group…and again, assign them to the frozen layer.
2:28 Let’s also not forget to delete, or freeze, this top handrail as well
2:36 Now we have a nice big hole in our planting area.
2:39 Let’s patch the cheekwalls next.
2:42 To do the walkway cheekwall, we can use the ‘FollowMe’ tool.
2:48 Draw and arc as our guide…
2:58 ...then select and use the ‘FollowMe’ tool on the edge of curb to extend it.
3:05 Next, we can exit the wall group and jump into the planting area group.
3:10 We have to make a choice here given that this planting area was created using the ‘Soap Skin Bubble’ extension.
3:17 We can either see if ‘Sandbox’ can patch it by using the ‘From Contours’ tool or just delete and re-do the whole planting area again with ‘Soap Skin’.
3:28 Let’s try ‘Sandbox’ first and see how that goes as I’m assuming it’ll be a little bit faster.
3:34 We need to draw a bottom arc first for the bottom of the slope.
3:40 Then select the top, bottom and one part of a side edge and then run ‘From Contours.
3:49 We can then explode it and match the material.
3:54 The 'Fom Contours' patched it pretty easily but since it didn’t bulge out like ‘Soap Skin’ does, it may stand out too much from the other planting areas.
4:04 It’s also clear where the sharp wall corner was originally.
4:08 Since that only took us a minute to do, let’s try it again with some help from the extension.
4:15 Let’s delete the entire surface leaving just the edges.
4:22 Since we’re re-doing the whole thing, let’s also take the time to round out the top edge where the slope and flat parts of the wall originally were.
4:38 Now we can select all the bounding edges and apply a skin to it.
4:48 nd then enter ’30’ for the divisions.
4:57 Let’s try ’25’ for the pressure.
4:60 And remember if the faces are reversed to enter your ‘pressure’ in as a negative number.
5:07 And then we can enter the new planting group and smooth it out.
5:15 Lastly, we can sample and apply the planting material again.
5:22 And that’s it. Pretty painless after all.
5:26 I know that wasn’t a big change to have to make but the principles behind the process stay the same even as the size or complexity of the revisions increase.
5:36 As long as the geometry is grouped and layered separately from other parts of the model...
5:41 ...then going in and isolating, freezing, deleting, assigning to different layers, or even redrawing pieces from scratch shouldn’t take too take too much time or effort.
5:54 And don’t forget that we have our CAD linework above our site as well in the event we need to re-import the CAD base and either drape or use the ‘swap and drop’ technique to revise other parts of the design.
6:09 So that’s it for ‘SketchUp for Landscape Architecture and Site Design’.
6:15 We hope that you enjoyed both structure and depth of these courses and hopefully feel confident that after completing all the lessons, that there is very little left to hold you back from becoming an expert site designer and modeler.
