![]() This instrument is fixed to the drawing board at one edge with the help of screw provided for the drafter. The scale set contains two scales connected perpendicular to each which cannot be separated. It contains two arms which is adjustable to required angle and at the end of the lower arm a scale set is attached. Mini drafter is an instrument which can be used for multiple functions in drawing. Different types of drawing boards and their sizes according to IS classification are listed below #13. At the edge of board, straight ebony edge is provided for the T-square usage. The wood portions are joined by tongue and grove type joint to prevent cracks. It is used to support drawing sheet, so, the size of board is made according to the size of the drawing sheet. It is generally made of soft wood and it is in rectangular in shape. The surface of sheet must be smooth.ĭrawing sheets are categorized into different types commonly started with ”A” Drawing sheetĭrawing board is another one of the top 15 drawing instruments we have discussed in this article and their uses. ![]() It should be white in color with uniform thickness with must resist the easy torn of paper. The sheet used for engineering should be of good quality. Drawing sheetĭrawing sheet is a white paper on which an object is drawn which is available in various sizes. Hence, it can be termed as adjustable set square. It contains one adjustable wing or strip which can be adjusted to required angle. It is used to draw parallel lines to the inclined lines. ClinographĬlinograph is an instrument among top 16 technical drawing instruments and their uses that we have discussed in this article. 45 set square has a side of 25 cm while 30-60 set square has 25 cm length on one side. One is 45 degree set square and another one is called as 30 – 60 degree set square. So, set squares make the work easier for this type of drawings.
