Critical analysis of Architectural drawing-Introduction to Architectural technology This unit an introduction to Architectural technology enabled me to learn to develop my freehand drawing and technical detailing skill required to operate and apply skills for use with Auto Cad. The detailing technique are the core of this unit and are key in understanding the representation of data in plan, elevation, section and detail and their relationship in designing architecture, placing construction details into the hands of the architect and contractors to follow, an essential requirement of the construction industry. We learned how Using manual methods of freehand drawings to explore ideas and represent them in scale. The information to enable the techniques learned for detailing come from textbooks, lectures, manufacturers and the building regulations. Utilising manufacturer’s computer aided drawings from web sites, web site had to be English/Metric and had to be correct, some need to be altered to fit in a professional manner and correct scale. I felt I engaged in the sessions, I like independent studies where you rely on your own preparation and timescale, and representation of building construction methods and materials. We were given the right amount of flexible study time enough time to ensure that I could always catch up if I got behind. The amount of work I put in varied considerably from week to week. My engagement and attendance was always good and I never got behind on the scheduled time table. The feedback I got back from verity and John Meech each week was good, class feedback exercises were good and helpful and the conservations I had with verity and john let me know exactly how much work was required and the level of detail that would satisfy the brief. I don’t think at any time I thought I was falling behind with the work or finding things difficult or that the work wasn’t manageable. The key skills were based around an introduction to Auto cad other skills were managing your work by preparing free hand sketches that are the main information exchange mechanism alongside CAD. The inclusion of standard drawing conventions and symbols allow the content to be correctly interpreted. Individual drawing styles can be adopted, and improved on, showing the right sources of information in a clear representational style. Manufacturers specification were utilised to the correct sizes specified and the right materials selected this was the practical side, to prepare for the assessment. We were taught to use the correct line weights and explode the drawings to show Membranes and use Hatch patterns and batting lines for insulation, concrete, wood etc. Sections were prepared for using guide lines a layer you could switch on and off for when and where they would help. Building up layers to represent each element of the drawing in order to organise your work better giving each layer a title, was requested and also it was suggested that each layer (colour) could be set up so each colour represented a line weight. Annotations need to be set up so they appear the right size I chose to use city blue print as my font. The final layout had to be plotted on A1 paper scale making a print layer for the borders of the drawings that could be switched off in the layers menu so it won’t print. The part that was challenging was selecting sources that were creditable and apply with the correct building regulations, planning and designing. Using 2D CAD tools to edit and copy drawing content provides an easier way to present information. You should always and I always will, work on and keep an up to date research folder to gather and store information on each project you work on, providing you with basic information for future use. We engaged in using lots of tools like scale, trim, move, copy, hatch, Stretch, polylines and a whole lot more. PSLT SCALE then 0 then Regenall gets rid of any problems with scaling problems when plotting
your work! All my drawings showed areas of detail and the right amount of detail. I chose Rockwool for all the insulation in the building. They make insulation for Rafter level (Rockfall), separating floors(Rockwool flexi),Cavity wall insulation(Rockwall cavity) and they also do Rockfloor for ground floor insulation. I got details from Velux websites for the roof windows. I chose Bridgewater roman tiles from Sandtoft originally made for roofs in Dorset. Instead of timber beams from TRADA I used TJi joists and rafters to span the lean too with a 15o pitch and for joists in the roofs. To cope with the 15o pitch I chose a tile from Sandtoft.
