Create New Calibration

Before creating a new calibration, remember to ensure that the required drawing plan is already available as a PDF file in the same project where you need to calibrate the federated model (Only PDF file format is supported for 2D calibration on 3D model files).

Once ready, open the model where you need to calibrate the PDF drawing plan available in your project folder.

While viewing a federated model is open in viewer, click on 'Calibrated Drawing' icon available at top right side.

It will open a layered screen with an option called 'Create Calibration'.

Click on 'Create Calibration' to start creating a new calibration on the federated model open in viewer.

On the next screen, you are able to see list of all PDF files available in selected project along-with folder tree at the left side. Select the PDF drawing plan based on which you need to create calibration by clicking on the corresponding radio button, then click on 'Calibrate' button at bottom right to continue. In the example screenshot below, we have selected a PDF plan for ground floor location.

It will open a screen where the selected PDF plan will show opposite the federated model for calibration.

Now, you need to select base and target point in 3D viewer to calibrate.

To continue, set a base point in the 3D model and do required calibration as shown in the example screenshot below. Click on the first point and drag the mouse to the target point for calibration. Scroll your mouse back and forth to zoom in or zoom out as required. A red arrow will appear for selected points.

In the example screenshot below, we have selected a portion of the ground floor in the 3D model (showing on left side).

Click 'Continue' to proceed further.

Now, you need to select base and target point in 2D plan to calibrate.

Similar to the earlier step for 3D model, set a base point in the 2D plan and do required calibration as shown in the example screenshot below. Click on the first point and drag the mouse to the target point for calibration. Scroll your mouse back and forth to zoom in or zoom out as required. A red arrow will appear for selected points.

In the example screenshot below, we have selected a portion of the ground floor in the 2D PDF plan (showing on right side).

Click 'Continue' to proceed further.

The 2D-3D hybrid view will open. Now, you need to select single object from the 3D model to continue. Depending on the base and target point selected in earlier steps and also the single model object selected in this step, the 3D model calibration will happen with the selected 2D PDF plan.

Select a single object from the 3D model to continue. In the example screenshot below, we have selected a door (highlighted in yellow) which can be visualized as an object on the ground floor in the selected 3D model. The system will set the drawing calibration of central depth of selected object.

Click 'Continue' to proceed further.

In the next step, you are able to confirm the calibration that is happening as an overlay view and see how the calibration is happening on the selected 3D model based on the 2D PDF plan selected for calibration, combined with your selections in the earlier steps.

The 2D drawing will appear in transparent mode over the 3D Model and it'd cut the model over that plane in the view. You will be able to click on the transparent layer showing at the top of the 3D model on screen and make adjustments if required.

Click 'Continue' to proceed further. System would calibrate the height of calibration over the center of each selected object.

In the next step, you are able to save your calibration by giving it a name or a label (can include a prefix and suffix). Prefix can be alphanumeric, while suffix can only include numeric values.

Click 'Continue' to proceed further.

A prompt will appear stating 'Calibration done successfully' which means your calibration is successfully saved. The calibration of a drawing will be done with Doc Ref irrespective of the revision of that Doc Ref so that you can use the same calibration with different revisions of the drawing.

View Existing Calibration

While viewing a federated model is open in viewer, click on 'Calibrated Drawing' icon available at top right side.

It will open a layered screen along-with a list of existing calibrations created on the model open in viewer. You can search for a saved calibration with its name, as well as sort the list based on calibration name, doc ref and date if required by clicking on respective column headers.

In the listing, click on 'Parallel View' icon corresponding to the name of calibration you want to view, to get a parallel view of the selected calibration.

In the 'Parallel View', you can continue navigating in 3D model or corresponding 2D drawing and the navigation pointer for both 3D model and 2D drawing would work in coordination with each other.

Accordingly, click on 'Overlay View' icon corresponding to the name of calibration you want to view, to get an overlay view of the selected calibration.

Click on 'More Options' menu icon with three dots to see relevant options for the corresponding calibration - 'Copy Calibration' and 'Delete Calibration'.

Copy Calibration

To copy selected calibration plan to another floor or level. For example, if the original calibration was for ground floor, and you need to use the same calibration for first floor, you can use the option to copy calibration to use the same PDF drawing plan. Clicking on the option, it will open selected calibration with its 2D-3D hybrid view.

Select the object to copy the calibration for.

Once the user select any objects from single or multiple floors (e.g. Wall, Door, Column, Window etc.), clicking on ‘Duplicate’, the system would:

  • Create duplicate calibrations by coping the current row’s two-axis calibration (X-Y coordination and orientation) and

  • Set the height of duplicated calibrations (Z-Axis calibration) over the center of each selected object

After selection 'Continue' button will be enabled, click on it.

Enter a name for copied calibration, then click 'Continue'.

A prompt will appear stating 'Calibration done successfully' which means your calibration is successfully saved.

Delete Calibration

To delete selected calibration if not required any longer.
