Takeoff To The Next Level With Navisworks 2D And 3D Quantification

Takeoff to the Next Level with Navisworks Quantification Chapter 5: Formulas and Catalogs Catalogs Catalogs are the overall template structure for using Quantification. Catalogs can be saved and imported into Navisworks. Your catalog data can contain entries such as Items, Resources, and Formulas. There is also the ability to an Excel Catalog Template tool. This allows you to add data to an Excel spread sheet template, and then import the data directly into a Navisworks Quantification Item or Resource catalog. You can then recreate the relationship between your Items and Resources. The Excel Catalog Template can be downloaded from www.Autodesk.com/Navisworks. Formulas Formulas are created in Resources. You are able to add formulas for many measurements or quantity calculations that might exist within the industry. Formulas may consist of a mix of model derived data, such as Model Width or Length*Width*Thickness to create a Volume calculation, or individual calculations such as converting between units.

Takeoff to the Next Level with Navisworks Quantification Chapter 6: Model and Virtual Takeoff Model Takeoff Model Takeoff allows you to quantify your models form properties or selections directly in the model or Navisworks Canvas. To carry out model takeoff, objects must be a group, layer or model. If you try to takeoff a model object that is an instance, or if the object does not contain a GUID or properties, an error message is displayed. Ensure your workbook is in Item view before performing takeoff. Virtual Takeoff Virtual takeoff can be carried out when you want to add takeoff objects that are not linked to a model object or item, for example: Where an object has geometry, but has no properties Where an object does not have geometry, and has no properties This could be the case if you did not save the properties from the original design application with your file, or that the object you want to takeoff does not exist in the model. In both cases, you can associate a viewpoint with the virtual takeoff object so you can navigate your way back to it during the takeoff process. Once your virtual object is taken off, you can begin to add properties by using formulas, which provides quantities for the object. Exercise 6 – Model Based Quantification 1.

Takeoff to the Next Level with Navisworks Quantification Chapter 7: 2D Takeoff 2D Quantification 2D Takeoff allows you to measure lines, areas and counts on a 2D sheet that has been imported into your project. 2D Takeoff supports native and scanned DWF files. Non-native DWFs files such as PDF can easily be converted to DWF using print driver software for use in 2D Takeoff. The 2D Takeoff tools will only show up when a 2D sheet is selected in the Navisworks canvas. 2D Takeoff Tools 2D Tools Tool Name Select 2D Tools Tool Description Select a 2D Takeoff Markup on the sheet Polyline Use to draw a single line, or build up multiple line segments to make a linear polygon. Rectangle Polyline Drag a rectangle or square on the worksheet. Quick Line Select existing geometry in the model and use to create linear takeoffs such as walls or perimeters of a room. When selected, a popup menu appears from which you can select a geometry to highlight on the sheet (see options below). Area Record area measurements by tracing linear geometry. For more information, see Creating an Area Markup. Rectangle Area Record area measurements by dragging a rectangle or square on the worksheet. Backout Use to exclude a polygonal area of geometry from an existing area takeoff.

Takeoff to the Next Level with Navisworks Quantification Chapter 8: Taking Off with Sets Sets Defined Sets provide a powerful way to organize your objects inside a of model and can greatly speed and enhance the Quantification process. Search sets can be used from project to project as an import/export. Selection and Search Sets Selection sets are static groups of items, and are useful for saving a group of objects that you want to regularly perform some action on, such as hiding them, changing transparency and so on. They simply store a group of items for later retrieval. There is no intelligence behind this set - if the model changes at all, the same items are selected (assuming they are still available in the model) when recalling the selection set. Search sets are dynamic groups of items, and work in a similar way to selection sets, except that they save search criteria instead of the results of a selection, so that you can re-run the search at a later date as and when the model changes. Search sets are much more powerful and can save you time, especially if your CAD files are continuing to be updated and revised. It is also possible to export search sets, and share them with other users. Taking Off with Sets Once created, sets can be used to not only organize your model but used to quickly quantify groups of defined objects into the catalog. There are two methods for taking off with sets. First you can select the set from the Sets palette then locate the object in the Workbook, and complete your takeoff. Second your able to simply drag and drop you’re your set into the desired location in the workbook. Exercise 8 – Taking Off with Sets 1. Open Autodesk Navisworks Manage or Simulate 2016 and load the Autodesk Hospital Quantification.nwf file 2.

Takeoff to the Next Level with Navisworks Quantification Chapter 10: Change Analysis Change Analysis Change Analysis enables you to compare changes to properties between model versions. You can then review the changes to decide whether to give approval. If you make changes to your takeoff data in a project, you receive status notifications in Quantification that highlight what has been changed and what type of change has been made. Status Notification When an item or group is changed, a warning flag appears in the Navigation pane and a green or blue triangle appears in the cell. The overridden formula also appears in bold in the Item Catalog. Once Change Analysis is carried out, the following notifications appear in the Status column of the Quantification workbook.
