Once a model has been created, it is possible to relocate foundation positions en-masse with the use of Linear Draft's 'En-Masse Move' feature.
Firstly, you will need data determining the actual 'as-built' foundation easting and northing positions along with the top of foundation information for each structure (if different from the information in your model).
Once you have the information, you will be required to format the data into an excel document in the following way:
Each line represents a different structure. Column 'A' is the easting positions, column 'B' is the northing positions and column 'C' is the top of foundation height.
You now need to save the excel document to a location of your choice and in a .csv format.
Return to your model to import the data by selecting the 'En-Masse Move' button from the Linear Draft toolbar.
The 'En-Masse Move' form will be displayed.
The tolerance range of which foundations will be moved can be edited by typing in new values or using the up/down numeric controls located next to each field.
To import the .csv file, click 'Browse' and select the file from the saved location.
The information from the file will populate the form and all foundations that have new positions within the tolerance range will be displayed in the top box.
All foundations with a movement that is outside the minimum or maximum tolerance range will not be moved and will be displayed in the lower box 'Unused Coordinates'. Adjust the minimum and maximum tolerance to include any structures that are displayed in the lower box.
The 'Total Delta' column will display the total movement distance of the foundations in relation to the old and new foundation positions.
Click 'Move' to confirm. Linear Draft will rebuild your model with the new foundation positions.
Close the form to exit.
