I'm fairly new to this whole drawing up a site survey (on 3 yrs on CAD)

Any suggestions how to do it?

It really depends on what kind of data you have. If the survey was done with GPS and you have a datalogger, you can integrate the GPS points into a new CAD drawing (I'm assuming you have AutoCAD) and use them as references to complete the drawing.



If you're working from traverse data or a field book, then if you're in AutoCAD and have the Survey module it can be relatively straightforward. If you start by defining a benchmark point (some kind of 3D control) you can use the survey tools to run lines in the drawing just like they were surveyed, such as by bearing and distance, azimuth and distance, etc. This lets you cut down on doing coordinate geometry and the like.



If you're working in a basic CAD package that doesn't have surveying tools, then you might have to digest the field notes/survey data into some kind of form that YOU are able to work with them. You should start by drawing in things that have fixed, known locations (baselines, property lines, section corners, property corners, benchmarks, etc.) and fill in the missing information based on the survey data you have. It's kind of like a jigsaw puzzle in that sense -- the "fixed" things are like your outside pieces and it's easier to fill in the inside pieces once they are in place.



If you need more help or advice or anything don't hesitate to contact me.

I am an Electrical Engineer and to me a site survey would produce a report of the equipment condition and drawings of the system. This might produce an electrical schematic and perhaps a 2d layout of any equipment that requires it, and a2d site layout if required.



I am assuming that you mean a site survey to give you a plan of the site? In which case you need to consider the data you are getting. Some surveying instruments will do this automatically for you and all you do is import it and check it over.



If you are doing it manually, draw a sketch of the overall site, then do more detailed sketches of areas giving dimensions, length, widths and heights of the important details (for example, unless you want to there is no need to record where door handles are). Also get the dimensions of any important pieces of kit, or at least the outline of it





If you are new though the best thing you can do is to do a couple with a more experienced surveyor or CAD operator to get the experience - loads of things you can miss otherwise.

Well

A very good site that teaches how to draw realistic pencil portraits is http://pencilportraits.toptips.org



I have searched so many sites on the internet for so many years (wasting my time really) to try and better my drawing/sketching style but have never succeeded getting pasted the flat 2D outcome; that is until I tried using some special methods I found on http://pencilportraits.toptips.org. This is exactly what I have been searching for and with time on my hands I have the outcome I have always wanted. I bought this online course. I strongly recommend it.
