Convert AutoCAD Points into XYZ Points for Revit Toposurface


You can't directly convert AutoCAD 'Points' into a Revit surface. But you can convert the AutoCAD 'Points' into a csv with XYZ coordinates. Seems that contours come out a little smoother but if this is all you got it's better than nothing. Here's how...

Open AutoCAD file which contains 'points' 
Type DATAEXTRACTION
Create New, next
Give Name, next
Select current file, next
Filter only Points, next
Clear Show count and name, next
Output Data to external file, choose name and csv, next
Finish

Open csv
Delete header rows
Move all data rows up
Save (as CSV) and close

Open Revit
Toposurface
Create from Import, Points
Select CSV

Select Unit

Dynamo Simple, Practical Examples: Write Family Type to Type Comments

When writing one instance parameter to another you use the 'get and set' method. This does not work for Type Parameters (wish it did). The best way to explain in this case is to show the image of my Dynamo Graph:

Why might you use this? You can't filter a Schedule by Type (wish you could) but you can filter by Comments.

Disable Optimized View Navigation in Revit 2017

Problem: 
When you orbit your Revit model the outlines and hatches disappear. I find this effect very ugly and defeats the purpose of examining your model in 3D using Orbit. Revit used to have a simple checkbox in the Options-Graphics dialog to disable or enable, but not any more. Now we need to edit the Revit.ini...sigh.

Solution/Workaround:

Add text OptimizedViewNavigation=0 under the [Graphics] heading in the Revit.ini

The Revit.ini can be found here:

C:\Users\\AppData\Roaming\Autodesk\Revit\

Add the text here:

Discalimer: Read this Revit help before editing the ini...

Dynamo Simple, Practical Examples: Export Coordinate info to Excel


Dynamo Simple, Practical Examples: Draw a Revit Floor


Dynamo Simple, Practical Examples: Draw a Revit Wall

Learning Dynamo is hard. Is it worth it? Yes, it offers great potential in a number of areas. Here are a few things that Dynamo can help you with:

  • Importing and Exporting Excel data very easily. Beside being able to use this data in Excel, this provides a bridge to other software like Inventor, Solidworks and more. For example you could export points from a curtain wall in Revit to Inventor or vice versa. 
  • Automating the placement of Families. Good example is auditorium and stadium seating. 
  • You can connect parameters from one Family to another. For example connect the floor thickness to the wall top offset.

Because it's hard to learn I would like to provide a few simple (practical?) Dynamo examples. Here's my first...a Dynamo Graph which shows you a way to draw a wall in Revit using Dynamo.

Floors Auto-Attach to Walls Bug

This is not new. I want to blog about this because it needs to be made clear. Floor sketches will lock to Walls regardless of using the Align and Lock tools or Pick Walls Tools. What this means is that Floor edges will move with Walls if the Floor sketch referenced an Osnap on a Wall or was Aligned to a Wall (without Lock). Autodesk, please fix this. We need to be sure that the edge of a Revit Floor will not move (unless we move the Floor sketch line). Floor Slab edge drawings are critical to a construction project and must be 100% reliable.
