Looking for something?

27 May

HOK BIM Solutions: Looking for something?.

General

Element is visible in other Views

Open another view or draw a new one.. If the element shows up, it may be one of the follow settings:

Workset
What Workset is the element on? Check the setting in element properties from a view where it is visible and  then check the VG settings in the view where it isn’t visible. Or turn on ALL Worksets through VG.

Wireframe
Elements can be covered up by other elements or even masking regions, change the view to wireframe to make sure this isn’t happening. If so, is the element at the right elevation? The family may need to be modified to show correctly, or the covering element can be made transparent.

Reveal Hidden
The element may be hidden in the view, or by VG category. Turn on the light bulb to shows elements hidden one at a time or by category.
*Elements hidden by Workset will not show up in this mode.

Visibility Graphics
Check the VG settings to make sure the category isn’t turned off.

Visibility Graphics II – Revit Link
If the element is coming from a linked model, you may need to check the custom VG settings in the Revit Links tab. If a link is set to custom or “by linked view” then it’s VG settings won’t come from the regular view settings.

View Range
Is the element within of the view range? Draw a section where the element should be and see what elevation the element is at. The default cut plane is at 4’-0”, so elements above this will not show, nor will elements below the view depth. You may need to reposition the element, change the view range, or modify the family to make it show.

Design Options
Is the project using Design Options? Cycle through each of the options in the VG Design Options menu.

Phasing
Is the project using phasing? In View properties set the “Phase Filter” to none, this will ignore the phase of an element and show everything. If the element reappears, it may have the wrong phase or the view properties may be set incorrectly.

Filter
Does the view have filters applied? Check in VG and turn on ALL of the filters.

Family Properties
Edit the Family and go into the view that you are trying to see the element in (Plan, Front or Side Elevation etc.. ) Select a single part of the element and go to the “Visibility Settings” button from the toolbar. These settings can turn off any element in plan or elevation views and coarse, medium or fine detail levels. Within the project you can also change the detail level of the view between coarse, medium and fine.

Element is not visible in other Views

Workset
Is the element on a Workset that is turned off by default? Turn on all Worksets on in VG

Worksets II
Go to the Workset manager from the Collaborate menu and check that the Workset is open and not closed. Closed Worksets are unloaded from all views in the model.

Detail Lines
Element drafted with details lines, symbols or detail components will only exist in the view where they are drawn.

Family Properties
Edit the Family and go into the view that you are trying to see the element in (Plan, Front or Side Elevation etc.. ) Select a single part of the element and go to the “Visibility Settings” button from the toolbar. These settings can turn off any element in plan or elevation views and coarse, medium or fine detail levels. Within the project you can also change the detail level of the view between coarse, medium and fine.

Design Options
Is the project using Design Options? Cycle through each of the options in the VG Design Options menu.

Phasing
Is the project using phasing? In View properties set the “Phase Filter” to none, this will ignore the phase of an element and show everything. If the element reappears, it may have the wrong phase or the view properties may be set wrong

Revit Architecture – underlay

27 May

HOK BIM Solutions: Revit Architecture – underlay.

When working in a reflected ceiling plan, it is helpful to know where the furniture occurs.

Revit provides UNDERLAY tools to make this easier.

You can work in the Ceiling Plan while viewing the Floor Plan as an Underlay.

NEW – You can work in the Floor Plan while viewing the Ceiling Plan as an Underlay.  (this can be useful for MEP tasks).

The examples below, show a floor plan and a reflected ceiling plan

Revit – 2D vs. 3D AutoCAD Backgrounds

27 May

HOK BIM Solutions: Revit – 2D vs. 3D AutoCAD Backgrounds.

There are two very different types of CAD backgrounds?

  • Flattened “2D” backgrounds that are overlaid onto a view
  • Model element “3D” backgrounds that have a physical location within the model

[clip_image003%255B6%255D.jpg]

How do you choose to link a dwg as 3D or 2D background?

Actually it doesn’t specifically say annotation or model, 2D or 3D… the option is found in the dialog box when you are first linking the background as “Current view only”

  • Checked will create a 2D background
  • Unchecked will create a 3D background

NOTE

Bringing CAD dwgs using Current View checked/unchecked it allows a user to control assigning the DWG to a workset or not.

Autodesk University – File Linking in Large Projects in Revit – DWG Linking

22 May

Autodesk University – File Linking in Large Projects in Revit – DWG Linking.

The five steps for reducing DWG links in a Revit project are:

  1. Define how the DWG will be used.
  2. Clean the DWG.
  3. Create a Workset for each link in the model.
  4. Link/Make Family/Import the DWG information.
  5. Update/Remove DWG links.
