Like a few people have said there are a few missing dimensions also I’m presuming that the aperture in the right item is central.
If you have the missing Dimensions feel free to PM me or reply here and I can send you a DXF File.
Just a little bit about cutting. Is this going to be cut out of steel I see you "Stock Plate" on your drawing. Water cutting gives a nice smooth edge but a big powerful water jet is required for cutting steel of that thickness. Lasers are more common and cheaper but you may not get a very smooth edge be prepared to do a little filing. Also consider other materials high grade aluminium is cheaper and providing on the grade still have very good strength properties and wont rust.

I'd guess that the company you want to do the work don't want to do the cad drawings for you because it is going to cost them more than the fabrication of the parts you want is worth to them - when you consider all of the back and forth for design confirmation and adding missing dimms etc.
I will say that drawings with missing dimensions are courting dangerously with the previously mentioned 'fag packet sketches'

They probably want a drawing so they can produce a part to customer drawing, ether that or they have to draw and then ask the customer to approve. If they draw they have to charge for it...
Jobs without drawings are a total pain to be honest, you produce them and the customer says they wanted it a little this and that different and basically you have to start again but they won't pay. I totally understand why they would want a proper drawing.
From a 3d step file I could knock most of those out of H30 machined quite quickly.
I understand the position from experts but were not engineers . We are just a couple of old guys tinkering in our shed making stuff and asking for a little bit of help .
Without some of the great guys on Ocuk stuff the little man would like to do would never get done .
I do appreciate the help and advice and i understand its annoying to see incomplete drawings .
Anyway the drawings are now amended as per previous posts and in the dropbox

no worries chap - I'm only yanking yer chain
Tbh I've seen far, far worse from qualified building surveyors, contracts managers, site supervisors, electricians, all with handwriting worse than my GP. You get the idea hehe. **** markups are a long-standing and deeply offensive insult to my drafting skills, especially when some ******** turns around and complains about why I'm asking for more information, or 'why is it taking so long, all you do is push a few buttons...'
'Yes mate, just a few buttons; like your job is just wrapping a bit of insulation tape round some bare wires innit?'

^ This haha, my worst one is when I am given an incorrect survey done by an architect and the erros in dimensions are only found out when the contractos are building the structure, I then have to change all my calculations and drawings which can take days to complete, holding up work on site. just gotta put loads of disclaimers on drawings so someone else takes the blame
measure twice, cut once
This is what lives on all of our drawings:
"All dimensions to be checked on site and NOT scaled from this drawing."
Along with the usual copyright/reproduction prohibition.
The worst case of 'crap survey dimensions' I ever encountered was in an old job when I was a fresh and optimistic cadmonkey. One of our steelwork subcontractors were tasked with sizing up a roof plant installation for some refrigeration condensers - Existing steels had to be married to a new condenser plant frame.
The new frame was duly fabricated and installed and job completion only required the delivery and installation of the new condensing units so the store could be re-opened for business to the public.
The big day arrived, complete with articulated lorry, mobile crane and various wigs from the companies involved. Police, fire service, ambulance and council representatives all standing about ensuring that the public stayed out of the town centre road which had to be closed during the moning traffic.
Everything proceeded like clockwork, with a minimum of blokes in hi-vis jackets, gesticulating and whispering into radios, whilst we all craned (haha) our necks skyward.
The new condensing unit arced its way gracefully into the air, until it eventually disappeared out of sight over the top of the building. With the fun over we began to move away anticipating a dull afternoon back in the office.
We were called back by the crane driver who reported a problem from the guys on the roof. Looking back up, all we could see were a couple of blokes in hard hats, peering down and waving their arms about.
This went on for some minutes until the crane lifted the unit back down on to the lorry.
From that point on the wigs did quite a bit of shouting, mostly at each other, until it emerged that the new frame had been built to the wrong dimensions! It was too wide on all sides for the new plant to sit on
What a day!
We learned a few weeks later that the guy at the steelwork contractors who ran the job was fired the next day. Poor bloke. I felt kind of bad for him, but it was an outrageously incompetent thing to do.
