Autocad MEP

  After some time off I have taken up blogging again.  This is a first post on creating custom content catalogs in AutoCAD MEP.  My thoughts are to expand this topic a little bit to include modifying the catalogs and moving content between them and then finally a large series of posts on creating all kinds of custom content.  Additionally, I hope to upload new downloadable...

  Recently a question was asked on the AutoCAD MEP forums about how to put the elevation of a Mass Element in a property set definition when neither the location or the elevation was available as an automatic property.  You can view the original post here.  Since this was very similar to a post that was covered previously on this blog it was an easy solution.  First...

New in Version 6.1 of Fabrication for AutoCAD MEP in the Select a Part dialog box SELECT PART SIZE area, the visibility and order of parameters has been optimized to reduce the need to scroll to the far right to identify differences between fittings. Important information will now list on the first few columns, starting with Part Size Name, Connection Diameters, NamePerMfg, and so on....

I get a lot of questions on schedules and property sets and instead of reinventing the wheel I thought I would point out a set of 4 videos by Jay Ayala of Autodesk.  Enjoy.   [video link="http://www.youtube.com/watch?v=QfgesH1dJr0&list=PLsTrqxAkk1TWeB9n8iOITvSxfqQCOiqMU&index=1" width="100%" height="350px" type="youtube"]   Concepts   [video link="http://www.youtube.com/watch?v=dtfalQ62oxI&list=PLsTrqxAkk1TWeB9n8iOITvSxfqQCOiqMU&index=2" width="100%" height="350px" type="youtube"]   Property Set Definitions   [video link="http://www.youtube.com/watch?v=lqMO47tiH0U&list=PLsTrqxAkk1TWeB9n8iOITvSxfqQCOiqMU&index=3" width="100%" height="350px" type="youtube"]   Tags   [video link="http://www.youtube.com/watch?v=1h8ziA115XM&list=PLsTrqxAkk1TWeB9n8iOITvSxfqQCOiqMU&index=4" width="100%" height="350px" type="youtube"]   Schedules    ...

There are two types of parts in an Autocad MEP MvPart Catalog.  A block based MvPart and a Parametric MvPart.  Block based parts are created from 3D solids or Mass Elements.  Additional sizes that are added to the part are done by creating a new block and adding it to the catalog drawing file.  Parametric parts are created using dimensions and constraints.  All sizes are...

  In the last post we looked at how to add an undocumented property to a property set definition.  This time lets try to add a formula based location property to a space object using the method from the last post. [frame bgcolor="#DDDDDD" version="light"] RESULT="NA" On Error Resume Next Set AcadApp = GetObject(, "AutoCAD.Application") Set MEPObject = AcadApp.Activedocument.Objectidtoobject("[ObjectID]") RESULT= MEPObject.location [/frame] When this property definition is created and made visible there is no information...

If you heavily use property sets then at one time or another you have found the need to schedule a property that is not readily available via an automatic property definition.  For example when creating a pipe system you can assign it a system family (commonly known as group) that will allow different systems of the same family to interconnect.  Systems that are not of...

In a heavily populated drawing you can accumulate alot of annotation tags and it can become quite difficult to see what they actually are attached to.  You can easily display the link between the tag and the parent object by some simple Display Representation manipulation.  Lets get started! First we need to start the display manager by either typing DISPLAYMANAGER at the command line or by...

In our last post we added to the duct elevation tag by creating an option to include or not include the insulation thickness in the elevation value.  This time we are going to add a manual property definition that will allow us to add a custom offset to each piece of duct.  This time instead of adding an option to include or not include the...

In our last post we looked at creating the actual tag based on property set definitions that we created in the first post of the series.  In this post we will be adding the ability for our bottom of duct (BOD) elevation tag to include or not include the insulation thickness in the elevation display.  Not only will we modify the elevation but we will...

In our last post we looked at creating the calculations necessary to create a bottom of duct (BOD) elevation tag.  In this post we are going to create the actual tag.  We will create multiple versions of the tag that has a middle-left insertion point, middle-center insertion point, and a version with a middle-right insertion point.  So lets get started. The first thing that we need...

For my first post I thought that I would start a series of posts on how to create tags and more specifically an elevation tag for duct.  The criteria for this tag will be that it needs the following abilities: [list style="style6"] Show bottom of duct elevation (BOD) Create the tag using a property set that is automatically attached to duct Show the bottom of duct elevation with or...
