AndyBard Posted August 28, 2007 Share Posted August 28, 2007 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. Quote Link to comment
Dieter @ DWorks Posted August 28, 2007 Share Posted August 28, 2007 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? Quote Link to comment
AndyBard Posted August 28, 2007 Author Share Posted August 28, 2007 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. Quote Link to comment
propstuff Posted August 28, 2007 Share Posted August 28, 2007 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? Quote Link to comment
propstuff at MJLA Posted August 29, 2007 Share Posted August 29, 2007 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. N.

AndyBard Posted August 29, 2007 Author Share Posted August 29, 2007 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. Quote Link to comment
propstuff Posted August 29, 2007 Share Posted August 29, 2007 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. N. Quote Link to comment
AndyBard Posted August 29, 2007 Author Share Posted August 29, 2007 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 Quote Link to comment
AndyBard Posted August 29, 2007 Author Share Posted August 29, 2007 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 Quote Link to comment
AndyBard Posted August 29, 2007 Author Share Posted August 29, 2007 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 Quote Link to comment
propstuff Posted August 29, 2007 Share Posted August 29, 2007 yep, one more thing, Model> Create Surface from Curves. then you should be right. N, Quote Link to comment
Dieter @ DWorks Posted August 29, 2007 Share Posted August 29, 2007 you can unlock it, it's in one of the menus Quote Link to comment
Thom Posted September 5, 2007 Share Posted September 5, 2007 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". Quote Link to comment
