Check that the following values are as requested:
  • COM port: Bluetooth-COM port name, e.g. "COM6".
  • Maximum deviation from surface (mm): Maximum allowed distance between a measured point and the wall. If the distance is exceeded.
  • Database library: The path to the library, in which documentation and drawings are saved.
  • Offset from wall (mm): Joint clearance between the wall and worktop.
  • Accuracy (mm): Maximum allowed deviation when calculating the set-up points.
  • Instrument: Instrument name. Choose from list.
  • Clean edges: Set the tolerance used for the automatic clean-up function.
  • Text height: Height of texts and dimensions in mm.
  • Language: Choose from the list.
Carry out this check before using the system for the first time and every time a new user is to operate the system and when making changes in the system.

Measuring

  • Start the L3Dprefab program and enter order ID:



  • If necessary place reflective marking on all the points to be measured. Place at least three control points. Place control points so they surround the area to be measured. Also place the control points at a reasonable distance from the instrument. On porous surfaces place masking tape beneath the reflective markings

    Place a minimum of two measuring points on each wall. If possible, place the measuring points at each end of the wall. Place the measuring points at the same height as that of the future worktop position. Place measuring points at a maximum distance of one meter.

    If the wall is not completely straight, place additional measuring points between the other points.
    When measuring to pipes, measure to the pipe centre (enter pipe dimensions during measuring).
    Avoid very acute angles, if possible. Never measure at angles below 15 degrees. If there are edges that cannot be measured directly, mount a lath flush with the wall and measure it to the positioned masking tape. The lath can be mounted using double sided adhesive tape. Only use this method on short edges below approx. 25cm.

  • Set up the instrument and switch on. Connect to the Bluetooth transmitter.
  • Adjust base screws to obtain a horizontal position. Check the tubular levels, which should be centred even if the instrument is turned 90 degrees. Place the instrument tripod on a stable base. In flats with soft flooring, the service operator should not move during measuring.

  • Click on Indstillinger -Measure:



  • -Follow the on-screen guide.

  • Measure a minimum of two control points. If you return to a control point, make sure to insert the right number:



  • Measure a height reference, this could be the floor or a socket. Select floor-level. If the reference is out of sight, off-set the point and insert the off-set distance. A minimum of 1 height reference is mandatory:



  • Measure the walls. Measure the walls in a natural sequence placing a minimum of two points on each wall. Be aware that seemingly straight walls can have huges fluctuations. To optimize precisionon long walls additional points should be measured along it. Be sure to measure at the right hight.
    Mutiple floors can be measured in the same sequence. To start a new sequence of walls click -Ny wall:



  • Measure profiles. First measure two basepoints to define a referencelinie. Select if the profile should be perpendicular to og parallel with the base-line. This can be changed by clicking on -New Profile. Select objedt-type in the list. Start new objects by
    -choosing a new object in the list.
    -clicking on -New Line
    -clicking on -Close polygon, that closes the active object
    You can draw multiple profiles from the same base-line, by clicking -New profile. You can draw profiles from a new base-line by clicking on -New wall:



  • Measure detailes. Choose between different object-types from the list. Depending on the type selected, you will measure
    -Points
    -Lines
    -pipes
    When measuring pipes, you should aim at the middle of the pipe. then enter the outer dimension of the pipe. The method is only sufficient on vertical pipes.



  • At the end of the wizard, you can either end measuring or continue to a -New set-up:



  • If -New set-up is choosen, you can continue measuring from a new position. Be aware that the first two fixpoints must be known points from previous positions.
    If you choose -End measurement you continue to: Validate fixpoints. Then measure at least one known fixpoint.
    In both opportunities the L3D wil validate, if the measurement still satisfies your demands on theaccuracy. If L3D encounters to huge errors, it will delete all data from the last accepted control of fixpoints.
    Hvis der er for store fejl, slettes alle mål siden sidste godkendte kontrol.



  • The measurement is now done. But you can return an continue at any time, as long as you start by measuring to known fixpoints.

    Postprocessing

    After measuring use the draw-panel to finish your template.
    The draw-panel contains a variety of tools:





    - Draw-tools to draw and edit templates, dimensions etc.:

















    - Suppport-tools, that ease the use of the draw-tools:






    - and -Layercontrol, that defines the object-type of the new drawing entities:

    In addition there is a number of special tools in the top panel, -offset of the back edge and front edge of your template, and -Clean edges, which will correct construction-errors like mismatching line-ends and overlapping lines. This function is born to make the template ready for use in CNC-tools etc.:

    12. Save the template:
    13. The template is now ready to go on to your workshop:

    Attention! You should always validate main dimensions and critical edges. Critical edges are:

    • Edges that was measured at a very narrow angle.
    • Edges that has been moved out (that was not visible from the instrument).
    • Edges designed based on dimension measurements.
    • Edges with a risk of reflection from glossy surfaces nearby.

    Be carefull to use correct layer when drawing.

    Maintenance

    If the total station has been exposed to damp conditions, wipe the instruments with a dry cloth and place in an OPEN instrument box.

    If the total station has been exposed to dust, dirt etc., wipe the instruments with a firmly wrung cloth. Keep the lenses clean at all time during operation.

    Always keep the total station and laptop in a dry and warm place. Always leave the instrument box open when storing.

    After use, leave the instrument batteries, laptop and Bluetooth to recharge.

    Home

    Test

    The system depends on the optimum function of the total station.
    Therefore always perform a self-check of the instrument six times per year. We also recommend that the instrument be sent for service at the supplier once a year.
    If the instrument has been exposed to bumps or other kinds of strain, a self-check should be carried out as a minimum.

    The self-check includes the following routines:

  • Set up the instrument on a tripod on a stable base. Carefully adjust the instrument horizontally. Turn the instrument through 200gon. Check that the levels are still horizontal.
  • Carefully adjust the sight to a control point placed at a distance of minimum 10m. Reset the horizontal axis (Hz=0) and note the vertical axis (V1). Turn the instrument through 200gon; and readjust the sight at the control point. Hz should now be 200.000gon and V should be = (400.000gon V1). Deviations of +/- 0.005gon are acceptable. Start the program and measure two known control points. Measure the distance between the control points using the dim-tool. Check that the distance is as expected. Variations of +/- 1mm are acceptable.
  • If one or more routines show errors, repeat the check. If it is not possible to achieve a satisfactory result, the instrument should be sent to the supplier for service.
