Lofting in autocad

harold

Is it possible to 'loft' in autocad?

depends on the version, but you can extrude along a path in the newer versions, which is basically the same thing.

Hi

What do you mean with "loft" ----- if you talk about taking out measures from a tradisional or a 3D plan , then yes this is what AutoCAD is made for ,but "lofting" is simply transfering scaled measures onto the materials that is then worked or calculating manualy from two planes onto a third that is then the shape of the workpiece --- well that's already there in the drawing.
Check these boat designs, they all are "lofted" on AutoCAD ;

3ds max uses the word lofting, which means making a 2d shape and then extruding it along a path. It comes indead from boating. For example, if you want to make a curving railing in 3 directions, and the section of the railling has a certain shape , then a lofting procedure works perfect, but i haven't found it is autocad 2005 yet.

Try the command 'extrude' you seem to be describing its function

extrude sounds right. Instead of specifying a height, type in p(ath), and select a line. Works best when the section you are extruding is aligned on the XY.

look up the "edgesurf" command. i only saw it once in some version 14 how-to book, but it has helped immensely with funky shapes in AutoCAD...

Hi

Edgesurf rulesurf and all other surfs don\t nessery produce a 3D Solid, maby with some you already get a swept Solid still Lofting sort of ask a reson, to loft the scaled plans objects, whatever you calculate manualy or digital, unto the materials to perform the object you loft.

True lofting can be selling the project doing it as a rendered promise, fact is that you know the exact limits but just using the renderings, is bad as then you don\t gain the savings and the progress in building methods, well you can render a totaly tradisional structure aswell as proving a brand new method ,and se how both will perform, but lofting remain a shipbuilding issue as long as you can find builders that master the process of bringing to live from projected drawings,
A 3D railing is proberly good for a rendering but to make things cheaper and stronger in a new digital building method, is somthing quite different. You Romans proberly is happy with 70 year old designs and methods rewritten into computer code, just doing things how they alway\s performed ,but even the method to bring shapes into 3D extruded objects , don\t make your thing 3D-HoneyComb can, ofcaurse if you want to break it down into somthing one third the strength at twice the cost, then call it modern architecture or design ,Cement was proberly interduced many times and even it was ideal for pyramides, bridges and houses er still forgot about it atleast tree times, so if you don\t reconise a spendid tool, that acturly make the computer work , well then the times just are not fit yet.
But Lofting you can\t take away from ships design.

Hi

When you se a fancy building or a nice design please don\t think that what is worth somthing, can be just what the attitude and surface reflect, --- real design have a core of innovation this make the structure not the surface.
To say AutoCAD sucks is alright when you know nothing about why AutoCAD sucks ,fact is that it work that it offer a number of tools but please don\t think new things have an easy time, that these day\s new technology is alway\s welcomed and is given a fair fight , if it was just that easy it proberly would be just as lame. Sure AutoCAD sucks about graphic presentations but you can still program a line to be drawn recursivly ,you can still draw with fractals if that\s what you want to play, I just wonder about profesional attitude < if AutoCAD sucks, then what about the ones that master it .

Hi
But you are right, there are software _much_ more efficient , AutoCAD I alway's had some cheap paint program as in terms of 2D graphic AutoCAD can't compare the simplest free-download program.
Also Solid modeling is done much smoother with other programs , I guess that when you first know the program, you just use it as -- well you then know a way to do it.
