CS1 Posted June 30, 2008 Share Posted June 30, 2008 How would I make a cylinderical object with curves? (like a hydroslide) I tried converting a circle to NURBS then dropping a few at different angles and heights and using the Loft tol, but had no luck. Quote Link to comment
CS1 Posted June 30, 2008 Author Share Posted June 30, 2008 Another example would be how would I make half a donut? Quote Link to comment
mike m oz Posted June 30, 2008 Share Posted June 30, 2008 There are 3D primitive plug ins which can be added to your workspace. Included in these is a torus object. Quote Link to comment
CS1 Posted June 30, 2008 Author Share Posted June 30, 2008 Thanks Mike thats a cool little tool. Is there any kind of spring object that you know of? Ive had a look at the available tools in my workspace and cant see one. Or do you know a way of using that Torus tool to appear like a spring, even if only for 360?. Quote Link to comment
Charlie_P Posted June 30, 2008 Share Posted June 30, 2008 To create a spring / spiral hydroslide... Draw a vertical line the height you would like your spring to be. Go to - Model-3d power pack-create helix/spiral Set the intended pitch etc. A spiral is formed.. Draw a circle representing the cross section of the spring wire (or hydroslide tube) Select both the circle and the spiral Go to - Model-Extrude along path Use the spiral as the path Hope that is what you were after Quote Link to comment
CS1 Posted June 30, 2008 Author Share Posted June 30, 2008 Thanks Charlie that is exactly what I needed. Have not used the 3D Power Pack before. Will have to do some experimenting. Quote Link to comment
Jonathan Pickup Posted July 1, 2008 Share Posted July 1, 2008 you could also try loft with one rail, or extrude along a path, using a nurbs path... Quote Link to comment
M.CH Posted July 1, 2008 Share Posted July 1, 2008 What about using the sweep tool, using pitch and to make 1/2 donut just draw a circle and place a locus and choose 180degrees Quote Link to comment
CS1 Posted July 1, 2008 Author Share Posted July 1, 2008 This is great I wasnt aware of some of these tools. Using the methods above I have created a "donut" the path (radius) is around 5000mm and the profile (cross section) is a polygon with around 6 different curves (basically a blob). Can some look at my signature and give an idea as to why my machine would run extremely slow once I try to render in openGL. It seems at this rate I wouldnt be able to make a very detailed model as it would just run too slow. I thought my machine was reasonably specd. Can provide more specs if neccessary.

M.CH Posted July 2, 2008 Share Posted July 2, 2008 Should render instantaneously in open GL, also if you edit or make a spiral object. The reason sweeps are good is that they only have the 2 essential components object and locus. Not sure why it takes any time to render, I've got the same graphics card Quote Link to comment
