hi guys 
does any1 know how to reduce an obj file size 

Ford Cortina MK3 by Dape - Thingiverse

i wanted to print the above file 
but it is 157mb in size 
Tinkercad limits imports to 25mb size files 

i have googled it .... but its way over my head
any help would be gratefully received  

thanks in advance

It looks like it's been modelled for rendering purposes primarily, so I'm guessing you'd need to disassemble the model into parts to make the file size smaller.

By which I mean separate out the body, wheels, interior, windows, wing mirrors, bumpers etc into different files.

I should stress that although I do quite a lot of 3d modelling, all of it is for rendering rather than printing, so I'm no expert.

Click the link on that page that takes you to partcommunity.com and you can download the .stl which is much smaller.

...it's only the fact I'm a 3D 'maker' myself I presumed 'file size' was referring to 3D printing, it would be much easier to find in a 3D sub forum like HRW & SCI.  I don't see 3DP as scratch building as it's a manufacturing process, you're not making it from raw materials your putting materials into a machine and it's making the thing for you.

I'd say that there is a scratchbuilding element to 3DP, though I think that mostly resides with the talented people that make the original files.

But it's an expanding area of our hobby, which covers many different areas.

Is it time we had a proper 3D forum?

It was 12 months ago, do it now or 3D posts will be all over the shop.

A 3D forum would be a great idea. 
 It would allow those who understand the 3D printing process to help each other with problems and would also help those of us who don't fully understand the process to know what is available and where we can purchase printed bodies, chassis etc and we might even get to understand a bit more of the process along the way.
 3D chassis and bodies are accepted by CSCRA (although some of the more traditional scratchbuilders may mark the car down in concours) because CSCRA recognise that building a car using a 3D chassis or fettling a 3D body still involves a considerable amount of work so although creating the files and printing parts is a bit of a niche section of the hobby it can benefit everyone who wants a bit more than just running cars straight out of the box.

A 3DP forum is easy to set up in a couple of minutes and may well be a good idea but some questions first:

Would it be strictly for the theory and practice of the printing itself or would it include what people do with the stuff after it is printed?

What about cars made from a 3DP body and parts - in the forum or put in scratch-building?

It would need a pinned introduction to the subject - a basic run down of what it is and how to get started. Any of you advocates of a separate forum prepared to do this?

[Kevan]

A 3D printing forum needs a whole different setup, I'll send you a pm

Reference starting a 3D forum, I suggest referencing it as "3D Design" rather than "3D Printing". If nothing else, printers now come in different flavours.
The design aspect is more skilled than the printing.
