# Track: Landscape and Site Design

Ya, we are seeing the same thing. Being logged into Campus returns errors. Very sorry.

For now, try watching without logging in at all. (You can simply close the pop-up window that will ask you to do so)

It should be fixed within a few hours, in the short term try to watch as anonymous.

TysonK, thanks for the tip. It worked great. Also, I just signed back in this morning, and the course is working fine now.

BTW - this is my first experience posting & response experience in the forum and itās pretty impressive.

Thanks again.

Hi there,

Is it possible to obtain all the precise height measurements to design the ramps?

Itās in inches and I donāt have a clue of what calculations you made to get those values.

@joao.p.arq Good question. This lesson was not intended to be a precise grading exercise. See attached for metric conversion. The goal is to have a consistent slope between each major zone. Of course in the real world we may need to include things like ADA (in the USA) landings, handrails, etc.

Here are the landings for you in Metric if helpful.

And donāt worry about specific dimensions. I was demonstrating how to draw vertical āspotā elevations in the event you needed your ramp to hit at specific points but like I said, for this demo, itās not important. Instead, try drawing a straight ramp from edge to edge and use the sandbox drape, or intersect with selection method (shown below) to get the exact curve/shape of each ramp.

1. example of flat ramp needing to get up to next level (0.9m above)

2. Draw flat plane representing slope connecting end points.

3. Group flat ramp and extrude up so it runs through sloped ramp.

4. Select both and āintersect with selectionā.

5. Delete extruded groupā¦group āextra bitsā and delete.

6. Finished result. Let me know if you run into any other issues.

Hey Eric-s

Much appreciated for taking the time give that information.

I donāt quite know why I havenāt changed to Metric yet. Must be cause the majority of youtube tutorials are North American.

Anyway, let me apologize for you going over that trouble, given that I eye-balled it and I think that I managed a fairly positive result. I was getting some weird twists and descents near the end of the slopes - particularly with the smaller walks - but a few measurement tweaks and it looked better.

Looks great. Thanks for the update. Keep up the good progress!

Iām following the course and got to the dwg import. Sketchup crashes every time I try to import the CC_DesignBase.dwg file. It crashes right after I close the import results window. Iāve tried several different times with different settings in the options dialog and it crashes every time. Any ideas to get this to work??

Sorry youāre having that problem. Iāve saw a similar crash recently myself. Let me look further into and see where the problem lies as it has been working fine up until now. Iāll report back.

Thanks! I also tried it in Sketchup 2019 - same result

Do you by chance have V-Ray NEXT Update 2 installed? Iām trying to narrow it down to an extension as Iām getting reports from others the file opens fineā¦and like I said, I know a few months ago it was perfect some something changed recently.

Edit - Feel free to use this file in the meantime to keep you moving forward.

I donāt have V-ray installed but I do have supodium.

Edit: Nevermind. I was trigger happy and paused the video and started doing it right away, failing to notice there wasnāt anything wrong.

Good to know. Its hard to watch and model at the same time. Glad youāre giving it a go!

FYI - I narrowed it down to the Skatter plugin that was causing Sketchup to crash when trying to import a dwg. Do you know how to notify them that their plugin is causing that issue?

Glad you got it working. I disabled all my plugins and my CAD import works now but hadnāt made the connection to which extension yet was the culprit. Iāll reach out to Skatter developer and see if they know what they problem is.

Back to Basics question:

Doing the modelling rocks step and I wish to know what and why this occurs. When youāre drawing free hand - on this specific purpose - the line fades away you end up with weird surfaces, or none at all.

But when I draw outside of the model, I get the drawing just fine.

Edit: Additionally, Iām having some trouble with Fredo6 round corner. I either cause a warning telling the 2" offset is too large or āAn error occurred in the Ruby codeā

Iām not sure why it works outside of the group instead of inside of it. Try drawing on the outsideā¦and then copy your rock outlines and āpaste-in-placeā inside the group to get them back in position.

For RoundCorner, have you tried Fredoās newer āFredoCornerā? That may work better than his previous extensions.

Re. Lesson 2, Walls and Curbs:

When trying to push / pull I get a message āCannot push/pull curved or smoothed surfaces.ā I did not expect this note. How do I solve it?

Maria

Hi @SunRay - Can you post a screenshot of the wall/curb that is giving you trouble? Some of the walls are made by using the Move tool as the intent is to slope the top of wall. If youāre getting that

message, itās likely that a non-coplaner surface has been introduced somehow. PushPull cannot work on surfaces that are not āflatā. Once I see specifically where your problem lies I can help further.

Here is the screenshot of the walls (dark green) I want to push:

Did you get it?
