What hatch to use for decking?

[sammo]

Hello all, I have a project to do where I have to design a bungalow, and I would like to have decking on the outside near the garden.

The problem is the drawing has to conform to bs8888 and bs1192 standards, and I am not sure what type of hatching to use to show decking to make it conform.

 

Thanks in advance for any help which I may receive.

Not sure but why not ansi31 its at 45deg as default but you can reset angle play with scale factor and you will end up with parralel lines at the decking width

Hi,

Do you have a copy of or knowledge of BS8888 and BS1192?

 

My understanding is BS8888 (not very much) appears to be relating to Mechanical / components etc.

 

BS1192 used to have 5 sections, relating to drafting principles, dimension styles, hatch patterns etc. It has been superceded recently (2007) and has omitted all of the above, and only provides guidance on "... the methodology for managing the production, distribution and quality of construction information, including that generated by CAD systems, using a disciplined process for collaboration and a specified naming policy..."

 

To answer your question, I do not think there is a correct / recognised pattern for decking, but good practice would be to provide lines to identify the direction you wish the decking to be laid.

 

I would suggest a User Defined Pattern, typically 100mm wide.

 

Hope this helps.

I don't think either standard addresses hatch patterns used for wood decking. My advice is to do a search for wood type hatch patterns on the Internet and try a couple out. One source for hatch patterns would be cadalyst magazine. One prolific hatch pattern maker is Watson Kilbourne. The guy is just amazing.

Just popped over to google and put in BS8888.

THESE are the results i got, let me know if they help

skipso: You know I did not see one mention of hatch patterns in the first three links I clicked on re: BS8888. Dimensioning, lettering and tolerances, etc. but no hatching.

i know what you're saying. from what i can tell there's no specific

hatch pattern.

 

It looks like as long as a key is provided and the drawin is clear

then the op should be ok.

 

I work in the building industry over here and i've yet to come

accross this standard as it's technical specifications but I

thought just in case pop the link up so the op could check it just

in case it does have the info.

With the exception of steel detailing I can't see where designing a bungalow would require the degree of technicality the standard calls for as regards hatching. That would be like asking the CAD drafter to differentiate between oak flooring versus bamboo. Would it really make a difference to the person looking at the drawing or the contractor how the decking was depicted? I thought that's why call outs and notes are used in drawings.

[skipsophrenic]

That's generally my understanding of it. when i'm depicting wood i

just use the generic hatch ANSI135 and pop in a leader with the note

"Refer to Note xx" and then detail description in the notes column on

the drawing.

the only detailing i use specifically for timber is using a light grey X (from corner to corner) on the sectional views of timber members. dont know if this is standard practice or just something drummed into me
