Creating slope on driveway ramp

The ramps on this driveway slope in two directions, from the left and right edges to follow the slope of the curb and also from the back edge of the ramp down to the curb. I am looking for advice on how to draw this.

Hi Rick,

Do you want the top of the slope to start at the outboard corner? Maybe like this?

Yes. That’s what I had in mind.

Well, here’s how I did it.

First I opened the low-cut curb component for editing and selected the edges that meet the apron components. I used Edit>Copy (Ctrl+C) to copy the selection to the clipboard.

Then I opened one of the apron components for editing and used Paste in place to paste the curve onto the front edge. I drew edges on the top and side to connect the curve with the top back edge of the apron.

I erased the top front edge and the one at the centerline of the apron, selected the edges around the hole and used Curviloft to generate the surface.

Completing the surface, check for correct face orientation and explode the group.

Repeat for the other component.

By the way, you could also use Extrude Edges by Rails from the Extrude Tools by TIG and available from Sketchucation. Or you can manually stitch the surface with the Line tool.

I see that the OP is using SU Make Desktop, so no plugins are possible.

That’s not true at all.

… and just to show that it can be done without extensions, here is a possible workflow using From Contours and manual stitching.

That’s why this forum is so great. Three different methods to accomplish the same result. Thanks to all of you.

Sorry for the confusion I confused SU Make with Web base SU.

Well, the file may help newbies with using the basic tools before plunging in plugins.
