Delete the family and model backup files created by Revit

Every time you save Revit automatically create these kind of files ,*.0001, that at the end of the day is filling up your hard drive with unnecessary files. Here you have the routines I’m to get rid of them. It’s very easy to make them work:

  1. Copy the 4 files attached in the zip files to the root of your family library or projects folder.
  2. Run DELETE_families backups or DELETE_revit backups.

Systemair Plug-in for AHU selection

Few manufacturers have developed their product catalogs for Revi MEP and in this post we talk about Systemair. Unlike others they didn’t send a huge full of families arranged at their discretion but a selection software for the AHU units and a plug-in for Revit that imports the file generated, as a family, in our project.

In the version I tested the families exported only had information about the  air connectors although the families parameters are not yet linked to the connector parameters.

The hydraulic parameters are not yet included, honestly do not understand why you skipped. As for the electrical parameters, as Systemair, not included by the installation of the equipment in situ are not typical configurations but still electricity consumption unchanged.

Manage the selection program has some difficulty and we leave Systemair experts who choose the conditioner that best suits our needs and send together with the financial offer SystemaAirCad file. For now this workflow is that we should lower.

Install the software

From their official website we download and install the software SystemairCAD selection, we will find in the “Global / Support / Software tools / SystemairCAD”. On the same page we have instructions on installing the plug-in for Autodesk Revit

IMPORT OF 3D MODELS TO AUTODESK REVIT

SystemairCAD is able to export a DMR file of a 3D CAD model.

A small plug-in have to be installed, to import the 3D model to Autodesk Revit.

The import plug-in together with instructions how to install it can be downloaded via the following link:

https://delivery.progman.fi/Delivery/Download/SearchProducts?searchStr=Systemair.

The purpose of the connection is to add Systemair air handling units selected with SystemairCAD into MagiCAD for Revit or Revit project and drawing.

Import an AHU

The plug-in offers two options for importing an air conditioner but we are going to focus only on the second, importing a file. “dmr” exported from SystemairCAD.

On the same page to download the plug-in found the Systemair Revit Plugin – Users Guide.pdf with details about the different ways available to import.

Forcing Yes/No parameter with If formula

[Google translate]

I could say that is a great find but the truth is that the information that follows is a derivation of other articles published on other blogs, wiki’s or websites.

Sometimes we are forced to use parameters of type Yes / No in creating Revit families is MEP, Architecture or Structure and control of this parameter via a formula is not entirely intuitive.

When we are in the situation of having to force the value of this parameter to True or False using a formula first tried putting a “= 1” or “= true” for true and “= 0” or “= false” to false but this does not work. There are several sites where they explain that these parameters obey the logic formulas as 1> 2 then this value will be True or 1 = 0 for a false value. The site that I like is the Revitforum.org for examples of using these formulas, the sloarch.com like revitforum.org has practical examples and moreover is the Autodesk WikiHelp introduces us to the formulas available but with few examples.

In this article we take the opportunity to show you how to make a control parameter forcing parameter value Yes / No If with formulas and logical relationships.

Family for electrical panel in Revit MEP

[google tranlation]

Setting up an electrical system in Revit MEP requires the adaptation of certain families to the standards in force in the country to perform the project. The following short video explains how to be the most appropriate configuration of the family of a panel board for the Iberian Peninsula. In previous articles explaining how to set a light to be accepted by an electrical panel and a system in Revit MEP. I leave you with the video.

Downlight Family, the electrical connector

Explanation of the basic parameters to configure a downlight, example deployable to any non-fluorescent lighting fixture, connected to a single phase power system with a voltage of 230V.

On the Autodesk WikiHelp page there is an explanation for each parameter seen in the video above. It is a good starting point to understand these type of connectors.

Hiding Revit Family Parameters in a Project

In the various Revit software packages, it is possible to hide family parameters so that they are not visible in the family’s properties when in a project file.  This is often desirable for situations where the family creator does not want the user to even know that the parameter exists within the Revit family.  This can be helpful for keeping the parameter from being easily modified or just keeping the parameter area less confusing.  Parameters that are used strictly for calculation purposes are an example of parameters that may be hidden.  Parameters that are used behind the scenes to control visibility of objects based upon other criteria is another example of parameters that may be hidden.

Some characteristics of hidden parameters include:

  • Parameters that are set to be hidden can only be seen and modified by opening the family in the Family Editor.  These parameters will NOT be seen when choosing the Edit Type button for the family’s properties while in a project file.
  • Parameters can only be hidden through the use of Shared Parameters, and only Shared Parameters can be hidden.
  • The ability to hide a parameter must actually be done prior to adding the parameter to the family.
On the Aplying Techonology to Architecture blog,  Douglas Bowers writes all the above and the steps needed for the configuration of the parameter visibility in his article Hiding Revit Family Parameters in a Project
