Not really telling us a lot there, though, are you? That sounds more like a difference in how it works rather than what the difference means to the user.

The main difference is that Sketchup is a tool meant for modeling structures for Google Earth program.

As SolidWorks and other mechanical CAD programs are professional tools for engineering. With these tools you can create structural frames, sheet metal parts, parts with very complex geometry, make drawings that are associative with the model from what the drawing is generated from. Then assemble those parts, run simulations for mechanical strengths, aerodynamics, thermal problems. Use CAD data for CNC manufacturing etc.

Some examples what I have done in SolidWorks:
Drawing of Roadsters base frame.
Drawing for my coworkers AC Cobra replica scuttle and firewall area
And those panels (flat patterns CNC punched and pressed then CNC bended) trial fitted Pic 1 Pic 2
Looking quite good, don't they? Can you do those things in Sketchup?

Can tomato sketchup create dxf files that can be read by cnc machines so your parts can be laser cut and or cnc machined? Because solidworks can...:)

This is getting a bit silly. OF COURSE SOLIDWORKS IS BETTER, no-one, least of all me, is denying that.


Please remind me how much Solidworks costs someone who is buying it, and then we can compare it with how much Sketchup costs.


Here is a list of what the professional version ($495) can do in terms of import and export. I believe that you can get 8 hours of demo use free, so you can create a model in the free version, then use 30 seconds of Pro time to export it in the chosen format.

The tinterweb is a wonderous machine, I got about 8 Siouxsie and the banshee albums in a matter of hours with as many if not more Cocteau twins albums say no more;)

Dubious moral ground though, isn't it. How would you feel if someone took moulds off stuff you've made?

I made a point of taking the piss at Stoneleigh a few years ago when I saw that Carbon Mods had copied my low side seat. If you look at the stuff they do it's all copies of Westy and caterham stuff.

Laws are made to be broken otherwise what is the point off having coppers:rolleyes:

Mr Henderson,

You started to compare SolidWorks with Sketchup.

For true mechanical CAD the cheapest option is Alibre Pro http://www.alibre.com/products/ad_compare.asp. It's not as mature as SolidWorks, Autodesk Inventor or SolidEdge, but it is also a lot cheaper than other mid range MCAD packages.
I will say again that Sketchup is not a mechanical engineering CAD software, although it can be used to make very neat models and schemes in PRO version.
For 2D CAD I sugest to check out fee DraftSight from Dassault Systèmes the mother company of SolidWorks.

What an extraordinary thing to say.

No, I didn't, I simply pointed out that it would be possible to draw up a chassis in Sketchup.

If it was legal to go as fast as you like then folk wouldn't bother, take CB's when they were illegal everyone and his hamster had one then they legalised them and no bugger wanted one.
:D :D

I was led to believe that the Roadster was done in sketchup but then i might be telling fibberoons again:D
