How to Create Tables and Generate Quantifications in Revit

Introduction to the Course

• The chapter focuses on creating tables and generating quantifications from a Revit model, allowing for extraction of quantities and costs.

• Previous content covered how to create sheets, import drawings, scale them, and export sheets to PDF. Viewers are encouraged to check class number 14 if they missed it.

Project Browser Overview

• In the Project Browser, there is a section called "sked quantities" (or planning quantities), which allows users to attach and collect all quantification tables related to their project.

• Predefined tables come with the project template; these can be reused in future projects without needing to recreate them each time.

Managing Existing Tables

• Users can delete existing tables that came with the template if they prefer starting fresh or if their template lacks any tables.

• To delete tables, select them using Shift + Click for multiple selections and then right-click to delete.

Creating New Tables

• There are various methods for creating new tables in Revit, each serving different objectives. The focus will be on creating quantity tables.

• Right-clicking on "sked quantities" reveals options for different types of tables including graphical column charts and material lists.

Understanding Table Categories

• When creating a table, users must specify the category of elements they want to quantify (e.g., windows or walls).

• Multi-category options allow for combining different element types into one table. Naming conventions can be established before or after table creation.

Working with Phases in Revit

• Revit allows projects to be organized by phases (e.g., existing conditions, demolition). Users can customize phase names according to their needs.

Understanding Project Phases in Modeling

Importance of Defining Phases

• When creating a project, it's crucial to configure phases before modeling. Without this, all elements are defaulted to a phase, which can lead to inaccuracies in quantification.

• If no phases are defined, the first step is to verify the phase of existing elements. For instance, if everything is created in phase one and you attempt to quantify phase two, it will yield no results.

Reviewing Element Properties

• To check the phase of an object in 3D modeling software (like Revit), select any object and review its properties; typically, they will indicate "phase one."

• It's essential to confirm that objects are assigned correctly since quantifying based on incorrect phases leads to empty results.

Creating Quantification Tables

• When creating a table for specific categories (e.g., doors), ensure you define what information you want to extract from those elements.

• Selecting a category like doors allows access to various parameters such as height, materiality, thickness, etc., which are critical for accurate data extraction.

Parameters and Data Extraction

• Each door has multiple parameters available for extraction including comments, cost, quantity, family type, fire resistance ratings among others.

• Understanding these parameters is vital because if certain values (like cost) are not filled out in the model beforehand, they won't appear when generating reports or tables.

Building Effective Tables

• When constructing a table for doors or other categories, clarity on relevant data points is necessary. For example: knowing both quantity and width may be important.

• The effectiveness of your model as a database relies on filling out all necessary information during the modeling process; otherwise it remains deficient when extracting data later.

Finalizing Table Creation

• After confirming desired parameters for your table (e.g., door types), ensure that all relevant attributes are selected and moved into the final table structure.

Understanding Door Parameters in Revit

Key Parameters for Doors

• The speaker emphasizes the importance of knowing door dimensions, specifically the width (ancho), which is referred to as "anchura" in Spanish.

• Additional parameters discussed include thickness (espesor), height (alto), and level (nivel) of doors, highlighting their relevance for project management.

• A table is created with five key parameters: name, width, height, level, and count (recuento), showcasing how these can be organized into a structured format.

Managing Door Tables

• The speaker notes that the number of doors in the project can be verified through filters; six doors are confirmed to exist within the model.

• The newly created door table appears under "scarel quantities," but it requires further customization to meet specific needs.

Customizing Table Information

• Options available in the properties panel allow users to edit fields after table creation. This flexibility enables adding or removing columns as needed.

• Users can filter data based on specific characteristics such as width or height. Filtering becomes essential when dealing with larger datasets.

Applying Filters and Sorting

• Filtering allows users to display only certain objects that meet specified conditions. For example, filtering by width could show only doors that are 70 cm wide while hiding others like those at 75 cm.

• Multiple filters can be applied simultaneously for more refined results. Users have control over what values are displayed based on their criteria.

Organizing Data Effectively

• Sorting options enable users to arrange tables by different parameters such as size or type. Ascending or descending order can be selected for better clarity.

• Adding footers or headers enhances large tables by summarizing information like totals per category, improving overall readability and organization.

Understanding Table Customization in Data Management

Overview of Table Features

• The speaker discusses the classification of items into categories, highlighting a scenario where five items belong to one type and one item to another.

• Introduction of the "Grand Total" feature, which aggregates totals at the bottom of the table for better clarity on overall counts.

• The option to group similar items into a single row is presented, allowing for a cleaner presentation without repetitive listings.

Customizing Item Display

• The speaker explains how to configure item display settings to avoid listing identical items individually, opting instead for grouped information.

• Emphasis on the distinction between creating a table and presenting information effectively; customization enhances usability.

Working with Larger Datasets

• Transitioning to larger datasets such as walls and windows, demonstrating how to quantify these elements similarly.

• A new table is created focusing on wall categories, specifying desired columns like type, material, thickness, and height.

Understanding Parameters in Walls

• Discussion about relevant parameters for walls including structural material and dimensions; highlights differences from door parameters.

• Clarification that certain parameters (e.g., height) may be labeled differently or not exist in the same form across different object types.

Advanced Quantification Techniques

• Importance of understanding wall heights based on levels; introduces concepts like "disconnected height" for accurate measurements.

• Suggestion to include additional values such as area and cost when quantifying walls; emphasizes relevance based on project needs.

Organizing Table Data Effectively

• The ability to organize data during table creation is highlighted; users can define order without needing separate steps.

• Explanation of how column titles dictate data organization within tables; users can rearrange columns easily using provided tools.

Finalizing Wall Data Tables

• Creation of an extensive wall data table showcasing various types and materials along with their respective quantities and costs.

Configuring Wall Parameters in Construction Software

Setting Initial Costs for Walls

• The speaker discusses setting a uniform cost for masonry walls, proposing a value of $45 per wall. This cost can be quantified in dollars and adjusted later as needed.

• After adding the cost parameter, the table reflects updated values. The speaker expresses a desire to filter out curtain walls from the display.

Organizing Wall Data

• The speaker notes that the current data is not well organized, with multiple entries for 20 walls and curtain walls appearing together. They plan to add a base level parameter to improve organization.

• A search for the "base level" parameter reveals challenges in locating it by name; precise naming conventions are emphasized when creating wall parameters.

Filtering and Sorting Walls

• Once all walls are associated with their respective levels, filtering options allow users to exclude specific types like curtain walls from view.

• The speaker demonstrates how to apply filters effectively, ensuring only desired wall types are displayed while maintaining an organized list.

Advanced Table Configuration

• The discussion shifts to sorting tables by various parameters such as level and thickness. Users can classify data hierarchically (e.g., first by level, then by thickness).

• Utilizing footers helps separate data visually by levels and provides totals for each category, enhancing clarity in project management.

Customizing Column Formats

• The total number of walls across the project is noted at 885. Further sorting options allow additional classifications based on user preferences.

• The speaker explains how to edit column names and formats within the software interface, allowing customization of terms like height or material type.

Displaying Values in Desired Units

• Adjustments can be made so that height displays in meters instead of centimeters without altering project settings. Users can specify decimal places and unit symbols.

• Customization extends to other columns such as cost or thickness, enabling users to maintain consistency across measurements while improving readability.

Final Steps: Presenting Tables on Sheets

• As a concluding step, the speaker mentions transferring created tables onto presentation sheets for better visibility during discussions or reviews.

How to Manage Tables in Revit

Positioning and Editing Tables

• To position a table on a sheet, it must be dragged from the views and placed appropriately. Adjustments can be made based on the size of the table.

• When dealing with large tables, column widths may need adjustment. For instance, if a column is too narrow, text may wrap onto multiple lines, affecting overall table size.

• Users can resize columns by selecting the table; arrows will appear to facilitate adjustments. This helps maintain readability and proper formatting within the table.

• An alternative solution for managing large tables is to split them into two parts using an icon that appears when selecting the table. This allows for better organization on the sheet.

Real-Time Updates in Revit

• One significant advantage of using tables in Revit is their automatic updates. Any changes made to the model (e.g., deleting walls) will reflect immediately in the associated tables.

• The ability to create and modify tables at any project stage ensures that information remains current when exporting or printing documents.
