Push pull on curves and angles

I am designing a garden on a large slope.

I am struggling to push and pull on the slant, I’ve attached screenshots. Does anyone have any tips or know any extensions that means I can push pull directly up on the slope? I want the retaining wall to be sitting on the 90 degree angle.

Any tips would be so so so appreciated!


Look for JointPushPull plugins from Fredo. Multiple options depending on what you are trying to achieve.

Take a look at this https://youtu.be/2RYaWpJ3puc?si=e2uq4qVdsmHB-8Bj
Artisan 2 is super useful

You can also model them flat on the ground plane, push pull them up and either intersect with the terrain and manually subtract geometry or use the solid tools depending on how your model is built - both would work.

Sort of depends on how you want them to look when they are finished. Will they step down with blocks or will they flow smoothly like the terrain below?

I want the retaining wall to push straight up along the blue axis and the curve to also smoothly push up 600mm. Does that make sense?

I’ve tried the Fredo extension but cannot get it to work for me!

With joint push pull, use the vector function (the icon with a v) that can pull along blue axis
You can also look for eneroth upright extruder plugin in the extension warehouse

I’ve tried a few times but cant get the curves to work!

I’ve popped my plans and slope into your file hoping you could try to see where I am going wrong? I am going to be working with slopes a lot in the upcoming projects so would love to nail this one & understand it!

I’m unsure of what you are trying to do / the result you are looking for but a couple more ways you could do this:

Use Push-Pull and Solid Tools. The footprint of your wall needs to be a Solid Component, Push-Pulled to a height that works for you:

Make the slope into a solid by adding a flat bottom:

Then use Solid Tools to Subtract the slope from the bottom of the wall (which removes the bottom part of the wall along with it).

Make a ‘reverse’ solid of your slope. Then use Solid Tools, subtract, to remove the top of the wall:

The remaining wall has the slope on the top and base:

Most block retaining walls are stepped. You can draw lines where the steps would be and push pull:

Place on slope and use Solid Tools if needed:

Good workflow. It would also be convenient to think about how it is going to be built. It would not be the first wall I saw that once designed there is no one to build it. It will need a foundation and it is not advisable that it be inclined but with steps.

Not to get too far afield from the Op’s question on Push-Pulling the wall, but to follow on @rtches comment:

‘Typical’ retaining walls not only ‘step’ on top, they also ‘step’ into the grade. In addition to that, they usually have batter and stagger… meaning each row is set back and the blocks in each row are staggered over the ‘seam’ of the blocks beneath.

These walls are made of individual block components that were placed and rotated along the curve. The second row was staggered halfway. Then I just copied both rows, moved them up and back an inch.

It’s important to know that and it is something that is almost always omitted in 2D paper plans. If each wall has 8 rows and each row sets back one inch the base and the top are 8 inches apart, so a total of 2ft for the 3 walls. It makes a big difference, so you want to convey that to the installers.

Here’s parallel projection:

Most designers don’t specify that they are showing the top or the bottom of the wall, and the scale of their plans doesn’t allow them to show enough detail to figure it out… So, I’m just mentioning this in case you are going to design for crews to install. It’s a stumbling point that you can avoid by including this info in your plans.

And for good measure, the side view stepping into the grade:

So, this is a much more manual way of drawing the walls. But it’s closer to how they are actually built. Hopefully that’s useful.

Without taking into account foundations. tHis is an example with artisan & sandbox

My contribution of constructive solution…

Both walls, the light gray and the yellow one would be executed as one, I have only put different colors to differentiate them
