static void pio_set_irqn_source_enabled ( PIO pio, uint irq_index, enum pio_interrupt_source source, bool enabled) The level for point Q is established by pulling the line tight from L to Z and marking the pin at Q precisely where it touches, so that the line L-Z is what is referred to as a 'flat bone' - a single plane, not necessarily "flat level", ie: no fall in any direction but a consistent, steady fall in one direction.

All that remains now, is to drive in marker pins at regular intervals along the arcs. The separation between marker pins will depend upon the radius of the arc. The larger the arc, the greater can be the separation between two marker pins. For these two arcs with radii of less than 5 metres, we would typically use marker pins at 600-900mm separation. From these two fixed points, A and D, we now mark out two arcs. These can be scratches on the ground, sand lines, spray paint, crayon or anything that can make a mark. From Point A we mark out a 6m arc, ie, the '3' side of the 3-4-5 triangle, and from Point D we mark out a 10m arc, ie, the '5', the hypotenuse. Where these two arcs intersect, Point E, marks the apex of a 3-4-5 triangle.These Setting Out Pegs have been approved under our Project Kaiyo™ initiative, accomplishing one or more of our environmentally friendly objectives. In this case, this product is made with recycled materials. Putting this knowledge to practical use, we can see from the construction plan for the driveway that the shape of the drive is constructed from a series of rectangles and arcs. The most important line to be set-out is the left-hand edge of the driveway, line A-B marked in red on the drawing, which is perpendicular to the front of the house, and is aligned with the left-hand edge of the doorway. To establish this perpendicular, we use a 3-4-5 triangle. has been chosen as the length of the base line A-D because it is a multiple of 4, the largest side of the 3-4-5 triangle other than the hypotenuse. The base line is regarded as true (accurate - a genuinely straight line), and so the longest available edge, ie, the '4' always goes along the base line. On the plan below, the marker pins have been positioned at 750mm centre to centre (c/c) along the arcs. Once in position, a taut string line can be fastened to the pins to create a line guide for the laying of the arcs. We recommend the Setting Out Peg for marking out temporary fencing lines and for hanging small notice signs. This product has been manufactured from sustainable softwood timber and is FSC certified.

For our right angled triangle we need to be as exact as possible with our measurements to ensure we get a true right angle at 90°, and not at 88° or 91°, so a measure is made along the front of the house, from the LH edge of the doorway at 'A' and a distance of 8m is marked with crayon or chalk at point D, just to the right of the garage door.

Steel Rebar Setting Out Pins

For heavy-duty applications, we recommend the Heavy Duty Fencing Pin. This product consists of Heavy duty barrier fencing steel pins for supporting barrier fencing. It is advisable to use a minimum of 1 fencing pin for every 5 metres when installing barrier fencing mesh. Our Fencing Pins are made of quality steel and are ideal for marking temporary fencing lines. They have approximately 8mm in diameter and 1370mm in length and feature a lamp hook for easy fastening of temporary fencing.

Our Profile Boards have also been approved under our Project Kaiyo™ initiative as they have been manufactured from sustainable softwood timber. Using two tape measures, these can be used in place of arc marking, provided that you can anchor the tapes ends securely at points A and D. Pull the two tapes towards point E, and where the 6m mark on the tape from A meets the 10m mark on the tape from D, is exactly point E. Drive in a steel pin to mark the point. We know that the gully at K is 90mm below R, so Points L and M need to be 125 - 90 = 35mm higher than point R, which means it would be 150mm - 35mm = 115mm below DPC level.

static void sm_config_set_in_shift ( pio_sm_config *c, bool shift_right, bool autopush, uint push_threshold) Firstly, Point W can be established by levelling across from the top of the gully at point K and allowing this 1.2 metre wide path to slope towards the gully by approximately 20mm, which is well within the 1:80 tolerance specified. So, point W is 20mm higher than Point K. Pins and pegs are used in surveying to mark points on the ground for reference. They are usually made of metal or wood and are driven into the ground to make a visible mark. They are important as they serve to separate the boundaries. Insulated Fence Pin: Used with temporary fencing, our robust and highly visible non-conductive fencing pins are available in standard (plastic spike) or with a metal spike, more suitable for installation into tougher terrain. Supplied in lengths 600mm / 900mm

The brief is to create a drive 7 metres wide, which is to align with the left hand edge of the front door, with a curved sweep on the right hand side to accommodate the double width garage and a smaller curve on the left hand side to tie in with a 1.2m wide pathway along the front of the property. The dimensions on the drawing states that the distance from the left hand edge of the front doorway (A), to the right hand corner of the property (C) is 7m + 3m = 10m. However, most landscape plans are drawn at a scale of 1:100 or greater, and will usually have an accuracy of around ±50mm. We provide varying types of flags in different colours to out specific areas/objects and are a very cost effective way to help with general surveying tasks. For other type of marking out then wooden stakes work well and our road pins are perfect for concrete form work. Now we have R, J and K established, the next critical levels to set are the high points on the driveway, on the break line L-M. We can measure that from the centre point of the break line L-M to the furthest gully, K, is approximately 10 metres. Using the standard 1:80 fall, we can calculate that the midpoint on line L-M needs to be......void pio_sm_set_consecutive_pindirs ( PIO pio, uint sm, uint pin_base, uint pin_count, bool is_out) In the absence of an automatic or laser level, we can use a straight edged timber and a good spirit levelto transfer the level from point R to points L and M, and then add 35mm. Small boat levels, 200-300mm long are not usually accurate enough for this sort of work, and so we recommend a spirit level at least 1200mm in length to be accurate when transferring the level by means of a straight edged timber, 3 to 4 metres in length. However, it is obvious that even a 4m straight edge will not span the distance from R to L or M, and so we set up a temporary intermediate level. Using a straightedge and spirit level to transfer levels They are used to mark the location of boundary lines, survey lines or other landmarks. In surveying, they also help mark or locate the points on the ground. You can also use pegs for marking or fixing road alignments, separating the boundaries of the properties.
