I am teaching myself solidworks and decided to build (on solidworks) the chassis of the +442.
I started off by building the bottom rail individual pieces and finally started the assembly mating the pieces together.
Apart from minor discrepancies within ~1mm, the F1 and F2 are off big time.
For E.g. according to the PDF page10 the F's are apart 155mm from the front. On my assembly they are a drastic 181.7mm

Now it’s either me or the pdf is wrong although I checked my work over and over. 
Comments please.
Thanks
I think E is too far forward.

Vheck your sizes again as not all of the tubes are measured from the same datum. From memory, one of the sizes is to the rear of a tube, and the next size is from the front of a tube, leaving a 25mm discrepancy. I'm sure I had the same bother drawing it in autocad BUT it does all fit together.
As stated you have got "e" too far forward (edit: I'll get it right yet!), which is causing F1 and F2 to be splayed out wider than they
should be.

"BUT it does all fit together" sure does

The drawing is full of rounding errors, also the inch to mm conversion is slightly off.
You would be better off starting again without using the angle dimensions and the lengths of C and E. The angles and C & E lengths will generate
themselves.
I drew mine in inches and scaled up (x25.4) so I got less missing fractions.

Can you read AutoCAD drawings?

No need I have posted a screen dump.
I used all the lengths given along the length of the car, the max width of the car, the 25" length and the 6.1" width between the F1 and F2,
the rest will generate when you add the box widths.
C and E are not exactly as McSorley but 34.4 x 25.4 does not equal 875 anyway.

Ok I understood. Thanks for the image.
I will contruct it using the base dimensions and the rest will fall into place accordingly.
I am working on another image showing the same dimensions as swown on Page10 on PDF but with different measurements.
Watch out for the front suspension pick ups, they definately are wrong.
Check out omega 24 v6's photo archive and you will see.
