The Future of Construction: Integrating Building Information Modeling (BIM) with AI Technology

-
The construction and architecture industries are poised for a technological revolution, driven by integrating Building Information Modeling (BIM) with Artificial Intelligence (AI). This powerful combination promises to enhance efficiency, improve decision-making, and pave the way for innovative project management and design solutions. In this blog post, we'll explore the benefits, challenges, and future potential of integrating BIM with AI, drawing insights from industry reports, case studies, and expert opinions.      Benefits of Integrating BIM with AI Enhanced Efficiency and Productivity : Integrating AI with BIM can significantly streamline construction processes. AI algorithms can automate repetitive tasks such as clash detection, data analysis, and report generation, allowing professionals to focus on strategic decision-making. This automation not only speeds up project timelines but also reduces the likelihood of human error. Improved Design Optimization ...

AutoCAD DWG Files unexpectedly increase in file size

-

Issue: 

Drawing files in AutoCAD end up being much larger than they should, often with no obvious data in them. Other symptoms include failure to copy and paste elements in the drawing, when selecting text with the properties palette open will cause the process to hang for a long time.  

 Causes: 
This happens when data is imported from a DGN file and the original linetypes were either incorrectly or not mapped to AutoCAD linetypes. This produces a huge object database in the drawing that cannot be purged with the standard tools. Furthermore, if you copy and paste an entity from the drawing into another drawing, the entire database is also copied, spreading the problem to the new file. 
  
Solution: 
There is a hotfix for AutoCAD to overcome this problem. The Hotfix includes two files:  
The DgnLsPurge.dll, once loaded will allow you to purge these DGN objects. 
The AcDgnLS.dbx is included to keep the DGN objects from propagating to new files when copying, pasting or inserting from other files.

 For AutoCAD 2013 / 2014: AutoCAD® DGN Hotfix 
For AutoCAD 2012: AutoCAD® DGN Hotfix for AutoCAD 2012 

 For AutoCAD LT: 
Try out the following procedure. 
  • Open the file with AutoCAD LT.
  • DXFOUT the full file.
  • In a new file DXFIN the file created in previous step.
  • DXFOUT the full file.
  • In a new file DXFIN the file created in previous step.
  • Purge all.
  • Save the file.

 Note: The problem is partially solved with AutoCAD 2014 and AutoCAD LT 2014 with the SP1 (the part to avoid the propagation with the copy and paste), but to clean the file you need to install the hotfix and run the DGNPURGE. 

 If you have installed the SP1 for AutoCAD and AutoCAD LT 2014: 
  1. Try the following procedure if the previous methods fail: 
  2. Open the file.
  3. With the LAYER command, assure that all layers are On, Thaw and Unlocked.
  4. Copy all objects in the drawing to the Clipboard (CTRL+C).
  5. Open a new file and paste all objects (CTRL+V).
  6. Save the file.
For Autodesk AutoCAD LT 2013, please follow the following workaround: 
  1. Open the affected drawing file using Autodesk AutoCAD LT 2013
  2. Enter DGNEXPORT at the command line
  3. Select V8 DGN under Files of type and click SAVE
  4. When the Export DGN Settings message box is displayed,
  5. Verify that the correct seed file and units are selected
  6. Click OK
  7. After the DGN export is complete, open a new template and enter DGNIMPORT at the command line
  8. Select the newly created DGN file and click OPEN
  9. Verify that  the Conversion unit is correct
  10. Click on Mapping setups and select new and make sure Mapping type is Import
  11. On the new Mapping setup, click on Modify…
  12. GO to Linetype tab, change all rows to ByLayer (Tip: Right click on the first row which has been set to ByLayer and the select Copy. Select all the Rows>Right click>Paste)
  13. Click OK

7 Tips and Tricks Why Revit Structure Elements are Missing or HIDDEN

-

Why Missing or Hidden: It is like hide and seek sometimes you are not aware you did it or surprisingly you don't.  Unless there is a plugin that pop-ups in you Revit someone who hides your modelled element. 1. Properties--> Under Structural--> Checked out or ticked the "STRUCTURAL". It depends on the discipline you are working on in the model. This happens when the 3D model element is showing but the plan and section are missing. 2. Look or Hit the Visibility Graphics? Under model categories, Annotation Categories, and Filter. It's all there for you to check and find out. For example, steel won't show a stick symbol. Check the visibility graphics, next model categories, look at the structural framing under that tick the stick symbol. 3. Reveal or un-Hide HIDDEN ELEMENTS. It's a blue bulb icon. Under the view control bar and reveals the elements you froze before. 4. Deleted or Purged. The only way you to chase the missing element is to look ...

How to Save Auto-CAD  Drawing as Read Only – is quite a difficult way to answer. The only way to answer this question is by giving different options for the user to Save Auto-CAD Drawing as Read Only. Let’s see some of them below. Save Auto-CAD Drawing as Read Only Some of the different methods are listed below please choose which is appropriate in your case. Method 1 – Use Save As Auto-CAD Drawing Files as DXF (Drawing Interchange Format, or Drawing Exchange Format is a CAD data file format developed by Autodesk), by this method you actually prevent the user to make any changes to your drawing files. Making the Drawing as Read-Only Files Method 2 – Ideally you could right click on the drawing file icon (once saved), go to properties and tick read only. Ahh, well that doesn’t “lock” the drawing or anything. they can still edit it, do a Save As, or simply unchecked the Read Only option for the file once they have it. Method 3 – In case you are on a Network, you can ...

How to Assign the Find Command to Ctrl+ F (a step by step guide) Just about every Windows application you own—Word, Excel, Notepad, your browser—uses Ctrl+F to launch Find… except AutoCAD®.  Hit Ctrl+F in AutoCAD and you get … .  Really?  Because F3 wasn’t sufficient? So let’s say we set Ctrl + F to be the Find command! How to Assign the Find Command to Ctrl + F:  Open the CUI dialog box by typing CUI at the command line.  Under Customizations in All Files, scroll down and expand Partial Customization Files, then expand Custom.  Now expand the Keyboard Shortcuts node.  Under Command List, drag the Find command up into the Customizations pane and release it next to Shortcut Keys to add it to the listing. MEMO:  If the recently added command does not initially appear in the Shortcuts pane over on the right, click OK out of the CUI, then re-open it and navigate back to the Keyboard Shortcuts node under Custom.  In the Shor...
