Edit Groups Containing Floors to Align Surface Patterns in Revit

Edit Groups Containing Floors to Align Surface Patterns in Revit

TIP: You must edit groups containing surface patterns to prevent the whole group moving when using the align tool to align surface patterns.Be aware of what aligns when using the align tool to align surface patterns when surface is part of a group.  The align tool does not effectively isolate the surface pattern poche if the element is part of a model group, rather the align tool will actually move the entire group to align instead of the surface pattern of the highlighted element.

Problem:  Designer wished to align two adjacent tile floor patterns in Revit 2012.  Watch as the align tool is used.

  When the second alignment pick is chosen to move the floor pattern in rm 103 in alignment with rm 107, the following occurs.
The result of the alignment tool is that the entire group has been moved rather than the surface pattern that was clearly selected.  Note the tooltip.
But, if you first choose to edit the group, you can pick outside of the group and effectively align the surface patterns as desired.

The final result is what was intended all along. Hope this helps someone out there.

Fixing Revit Topo Sub-Regions

Fixing Revit Topo Sub-Regions

Today, I ran into an issue with sub-regions in Revit topo surfaces and thought I’d share the quick fix with you.  Have you ever created subregions of a topo and at some point realized that you’ve in-advertantly created holes in the topo where you intended to create different material conditions. As shown in the image below, some grassy regions seemed to be displaced.

I found that if I deleted the grassy region by simply selecting the objects below the main topo surface, that I had to re-create new sub regions as it simply returned the “hole anomaly” shown in white on the surface back into the default brown region of the topo.  But if I edited the surrounding sub-region and removed the internal sketchlines, the hole disappeared and my grassy region returned.

When I noticed that selecting the surrounding region also selected the misplaced regions (they were highlighted in light blue as shown above), I chose Edit Boundary and tried deleting the internal or duplicated loops as shown in the image below.
The end result was the correct fix as it resulted in restoring my grassy regions to their correct location without having to recreate the outlines.  The corrected sub regions are shown below.
