... on a new modeling program ... what would be your first choice...
if you need exact, feature-based NURBS volume and surface modeling incl. history and support of all common cad interfaces, the only capable choice below 1,000 bucks is Shark LT, nothing else... SU import and OSX version too.
check the vids and get a 14 day trial.. and drop the rest

Ich frage mich nur wieso es auf diesem Rechner nicht schneller lÀuft als auf einem normalen System. Liegt es an der Programmierung der Software?
ja, wie mehr oder minder alle 3D Modellier-Kernel werden die Modellieroperationen nur single-threaded, also nur auf einem Kernel, ausgefĂŒhrt. Rendering ist was anderes, ein Rasterbild in Streifen zu zerlegen und auf verschiedenen CPU Kerneln zu rendern können viele.
hier hilft viel eben nicht viel, d.h. viele Kerne bringen fĂŒr SU nichts, sinnvoll ist also eine moderne = leistungsfĂ€hige und dabei möglichst hoch getaktete CPU anstatt mutipler, niedriger getakteter CPU Kerne welche wĂ€hrend der Benutzung von SU mehr oder minder nur DĂ€umchen drehen...
... vorbehaltlich anderer Applikationen (z.B. Virenscanner) und des Betriebssystem selbst welche aber zumeist mit dem 2. Kern eines Dual Core bereits bestens bedient sind.
Ein hoch getaktetet PIV mit einer schnellen GeForce ist daher um lÀngen billiger und vermutlich nicht viel langsamer als dein System... aber das weisst du inzwischen ja selbst.
ein (1) schneller intel Core 2 Duo dĂŒrfte also, zumindest vom PLV, die beste CPU fĂŒr SU/CAx sein.

Maybe Sketchup need to be less a visualization tool and more a CAD tool
surely not, the strength of SU is just not to be a typical and complex CAD but an intuitive 3D sketcher, nothing less, nothing more.
if you need a CAD, use a CAD
e.g. ViaCAD:

360 sides does not make a polygon a circle...
using real, analytic circles for creating 3D stuff based on them is much more complex than the handling of facetted polygons resp. wire frames only and would require to use another 3D kernel as e.g. the commercial products ACIS or Parasolids (= royalties!) or something programmed by Google itstelf.
and CAD is not only the geometric entities but also some further stuff as e.g. associative dimensions and advanced dimension configuring, GD&T, welding symbols, precise printing in scale, high entity support etc.

...model all those nice special shapes.
if you would like to model organic freeform shapes based on exact NURB splines with much less effort you may want check the Punch! ViaCAD series f. OSX/Win.
3D version starts from U$ 99.- (street price lower) and can import SU files too.
have fun,

...how it performed on the long run?
it's a netbook, not a workstation; the Atom CPU is not very fast by design, surely nothing for big models...
...and a 'mirror screen' too.

- The eye candy can be turned off.
yes, for looking similar like good ol' XP

- I find there to be less message in Vista than in XP.
the 'User Account Control' was a new feature of Vista... and intended to 'annoy the user', at least according to David Cross, a product unit manager at M$.
@thomthom said:
- Have you tested the drivers lately?
must admit that we did not have tested the latest revisions from end of Feb. resp. beginning of March, they are surely getting better and better... but testing should obviously not be done in a productive environment.
@thomthom said:
And Windows 7 use pretty much the same driver system.
sure, it's simply a revamped Vista 2.0, the way it should have been for the inital release.
@thomthom said:
I really disagrees that XP is automatically an more productive environment to work with.
Vista may surely work too... or not, XP does work.
just my 2 cents,

The Dells are way out on budget for my needs, and don't have HDMI output.
you may want check the Dell XPS or Inspiron series too, probably not as cheap as an Acer.

... outside in the garden
avoid the 'mirror' screens (Dell calls them 'True Life') if working outside or in a bright surrounding is ever an option.

... watching the occassional Blu-Ray disc on the TV without having the need for a stand alone Blu-ray player.
I would prefer a dedicated player, the BDPs from Sony are fine and pretty silent and affordable in the meantime.
@peweuk said:
I am not sure which of the processor/video card combinations would be best to go for???
the speed of one (1) kernel of the CPU is most important for SU, a recent intel Dual Core (e.g. T8xxx series or higher) is a good choice, 4GB work memory is no fuss/cheap, a bigger nVidia GeForce (not ATI Radeon) with dedicated memory (512mb is 'nough) should provide a decent OpenGL 3D output too.

XP? Why? Dog old OS.
since when does maturity disqualify?
not really, but instead:
our experiences and tests in the past w/ Vista video drivers in connection w/ the CAD systems we are distributing are pretty disappointing, just google for e.g. 'disable desktop composition' for getting further information on these issues.
in short, if you wanna be productive or if you maybe make a living from the results of your work, stay in general with the old dogs. If you wanna be top-notch or an early adopter, use the latest-greatest OS... preferably before the first SP is avail

if you plan to use SU not only for private or 'fiddling-around' purposes, avoid video sub-systems with video memory shared (slowly) from the working memory, i.e. the euphemistic nVidia 'Turbo Cache' or ATI 'HyperMemory' stuff...
...but buy a Dell Precision w/ Quadro FX video sub-system instead, at least if you can afford 
think of service and maintenance (e.g. new video drivers for upcoming OS as e.g. Windows 7) too.
hth,
Norbert
P.S.: try to get hold of a Vista with XP Pro 'downgrade' as e.g. Dell and HP are offering, at least for their business lines. Which will be available, if I remind correct, until mid of this year only.

...es muss ja auch keine Spirale sein. ... Es soll ein Rohr sein mit einer gewellten OberflÀche.
grob:
1.) einen "Gewindegang" der Spriale erzeugen
2.) m. Sandbox-Tools FlÀchen "wellig" verzupfen: "Fenster > Voreinstellungen > Erweiterungen > Sandkistenfunktionen"
3.) finalen "Gewindegang" axial zum Rohr vervielfÀltigen

@higgins99 said:
Ich möchte gerne ein Rippenrohr erstellen...
wenn man das Teil auf dem Endergebnis kaum, d.h. nur stark verkleinert sieht, könnte man natĂŒrlich auf die Spirale verzichten und einfach ein paar Scheiben auf ein Rohr setzen...
... SketchUp ist 3D Entwurf, kein CAD.

jo: fehlende Rechte
mach dich mal Admin und trage dann die Lic. Infos ein... danach sollte es auch ohne gehen.

I am also a sucker for well designed products- which the macbook is...
I would check if all of my apps are available for OSX before evaluating the design, it's still a tool.. but priorities may vary.
