Should This Project Be a “BIM Project”?

30 Jul

(bim)x: Should This Project Be a “BIM Project”?.

 BIM Decision Matrix – an algorithm that calculates which projects are candidates for BIM to add value. 

I would recommend considering the following project characteristics, based on the best available information. 

1. Construction Type (15)

New construction projects are best suited for BIM implementation, but renovation and maintenance projects can benefit depending on the overall scope of the project.

2. Program Complexity (18)

Teams see the value of BIM most easily on complex projects, such as labs and healthcare. However, factors in other types of programs can add value. For example, the replication of typical layouts in residential projects makes for good BIM utilization. 

3. Budget (25)

Budget is another major factor to consider in BIM implementation. The cost of implementing BIM becomes transparent on projects valued around $2M or greater. Plus, budget is a pretty good indicator of the scale of a project – another factor. 

4. Schedule/Timing (7)

Schedule impacts the potential value a project gets from BIM because of the mobilization time often required. The further along a project is, the lower the opportunity for using BIM.

5. Project Delivery Method (14)

Projects with a more collaborative contract form will benefit slightly more from BIM than other projects.

6. Team BIM Capability (15)

Team BIM capability can really impact the value a project gets from BIM. Honestly, the better project partners are at BIM, the easier it is to implement BIM!

7. Existing Building Documentation (6)

The form of existing building documentation is especially important for renovation and maintenance projects. Existing BIM data is the most useful; although CAD and laser scan data can serve as meaningful baselines when used properly. 

If you want to compare a few projects, you can use the numerical values included at the end of each factor. Use your best judgment to assign values to each category, and then add them up. The higher the number, the more likely it is that a project will benefit from BIM implementation. Considered 65+ a “proceed” with BIM implementation,

between 45 and 65 an “investigate” BIM implementation, and

below 45 a “reconsider” BIM implementation.

I keep this list at seven factors to stay in line with Miller’s Law. It really is easier to remember seven things. But of course, these are probably just a few of the factors.

Rendering Tips – The Revit Clinic

17 Jul

10 Rendering Tips – The Revit Clinic.

1.  Material with Image Transparency

The “Plastic” Material type contains an option for “Render Appearance”, “Type”, “Plastic Transparent”.  Along with this you can set the “Color” to “Image File” to utilize an image in the material.  With this combination you can make varied transparent materials containing image files.

3.  Section Box and Rendering Times

For more complex views, you can reduce the rendering times by enabling the section box in the view.  With the section box active, only objects that fall within the section box will be rendered.  This includes objects such as daylight portals or artificial lights.  For additional information I have included the technical solution link below:

Rendering only objects in current view or linked file

4.  Far Clip and Rendering Views

If utilizing a “Far Clip Offset” in a view to render, keep in mind the offset will not be calculated in the rendering extents.  The entire view range is calculated in a view when rendering.  If you need to exclude something in the distance, use a section box instead from the process in tip #3 above.

5.  Rotating Model Patterns & Materials

“Model” surface patterns can be adjusted by selecting the surface pattern and moving or rotating.  Doing so will rotate an instance of the material as well.  This is useful for overriding an area of the view for the rendering.

6.  Daylight Portals

Daylight Portals only work for interior views set to “Sun only”, or “Interior: Sun + Artificial”.  When checked active under the “Render Quality Settings” dialog they will improve the quality of light that shines through glazing objects.

7.  Light Fixture not Illuminating Scene

If you have a light fixture not illuminating verify one of the 4 following areas:

-Edit the family and check for geometry blocking the light source definition.
-Check any ceiling or object geometry potentially blocking the light source definition in the project.
-Verify “Lighting”, “Scheme”, contains “Artificial”.
-Verify “Lighting”, “Artificial Lights” are not un-checked or set to 0 for “Dimming”.

8.  Apply Materials to an Imported File

Linked or imported files can have materials applied to geometry.  Under “Manage”, “Settings”, “Object Styles”, “Imported Objects” locate the imported file.  You can expand layers and apply a material as needed.

9.  Material Texture Alignment

If a material has a surface pattern, you can use the “Texture Alignment” option under the “Render Appearance” tab to align the surface pattern with the render appearance.

10.  Sky \ Background Color

The sky \ ground color is based on the camera position in relationship to the horizon.  Two images below show the same “background” settings but with the camera looking down at the model versus up at the sky:

Looking Down:                    Looking Up:

Curtainwall System vs Curtain System

16 Jul

Curtain Systems:
-Can be applied to non-plumb faces of a mass or a generic model.

    

-Can only contain System panels (System family) or rectangular non-system panels

– Can contain a panel built from an adaptive component template

-Will form a curve by approximating it with straight segments.

Curtain Wall
-Is a drawn wall, so can only be plumb
-Can contain both Curtain Panels (in rectangular shapes) and system panels
-Can contain curved upper mullions etc that are actually curves
-Can be drawn stand-alone since it’s just a wall.

Save an In-Place Family as a RFA

9 Jul

What Revit Wants: Save an In-Place Family as an RFA for use in another project.

 

Open the Project containing the In-Place family

Edit the In-Place family

Select all of the elements in the family

Group all of these elements using the Create Group tool.  Give the Group a name.

Select the Group

Do not Finish Editing the In-Place family yet!

Go to the ‘R’ button (Application Menu) – Save As – Library – Group

You will notice that the filetype is RFA!

Save the Group somewhere.

You Component Family IS the file that you just saved.

I’m sure there are limitation to this method, but I think it is very cool.
