# Modeling help needed

## Recommended Posts

Hi All.

I'm trying to create a walkway through a garden that not only moves from left to right and back to left (like a 'C') but also starts at ground level, rises up in the middle before sloping back down to the ground at the end. Being a walkway the surface needs to be horizontal with the ground. Hope i've explained the shape.

To make do I have 'extruded up' the plan view shape and then rotated it along its length. This obviously doesn't sort out the problem of the walkway surface being horizontal with the floor.

I don't like making do and would like to know the correct way to achive this shape.

Can anyone help and either tell me how to achieve this or point me in the direction of a tutorial.

Thanks.

The walkway needs to rise 'and' be horizontal with the ground?

I do not think those two will happen.

Can you post a picture of what you want? or what you already have?

Hi.

The lenght of the path, the distance you travel from one end to the other rises then falls. whereas the width of the path needs to stay levelso not to feel as though you are being tipped off. I hope that makes sense.

If you start with a Polyline shape of the path in plan view and convert it to a 3D poly you can then move some of the verticies up in the Z direction to make a rise in the path.

Is this what you mean?

If you start with a Polyline shape of the path in plan view and convert it to a 3D poly you can then move some of the verticies up in the Z direction to make a rise in the path.

Come to think of it, converting to a 3D poly might make a Bazillion verticies if your path is curved.

Converting to NURBS should produce a shape that can be edited in 3D fairly easily.

Thanks!

I have just had a play and its so easy with them. I can get my desired curve and rise no problems. NURBS are the way forward.

My next problem is that i want to give the walkway a thickness, but I seem unable to extrude the NURB.

There are a couple of ways to do that.

First is the Shell tool which usually works,

the second is to duplicate the curve (or a different one) and use the Loft tool.

Hi.

I have had a quick read of the help for using the shell solid tool but i'm unable to select the nurb shape with this tool. Any ideas?

Thanks

The shape I have created is listed as a NURBs curve not a surface, is this the same thing or do i need to do something to it.

Thanks

Aplogies for all these little updates. Have have converted the curve to a surface using the 3d power pack menu. However no it says the surface is locked.

Thanks for the help so far

yep, one more thing,

Model> Create Surface from Curves.

then you should be right.

N,

you can unlock it, it's in one of the menus

Also, depending on what modules you have you can use a polyline for a center line, go to AEC, Roads, Station on a polyline, etc. and create a "mini-road".
