Roof Wall Connections

I feel like I have written this all somewhere before, but it begs repeating. Roof wall connections can be tricky, and solid element operations are not always the answer. In this example, we have an eave bearing wall running perpendicular to the roof slope.

The original model was built using SEO’s. This created a section error, showing the ceiling finish running through the wall structure:

Also, notice the selected wall is taller than it should be, running above the roof plan. This wall height should be modeled to stop at the highest intersection of the bottom of the roof core. Then the roof and wall, while both selected, can be cleaned up with the Merge function (Design > Connect > Merge, or Right Click > Connect > Merge).

The result is a properly cleaned up section view!

Schedule Criteria

We have looked at why doors and windows may not appear in an ARCHICAD schedule, or why they may not appear in their related zone before. Here is the link to that post, which is worth re-reading as a refresher.

The past couple weeks I have been getting more scheduling questions; more related to eliminating certain elements from a schedule, or why unexpected elements are showing up in a schedule. The answer is almost always due to an error in the Schedule Criteria Settings. Here we will look at a few scenarios that may cause undesired results with your schedules, all linked to incorrect criteria.

Fig. 1.0 Incorrect use of “and”Statements

In Figure 1.0 above, the Element ID that can be listed is using an and statement, rather than or. The result is, no elements will schedule, since it is impossible for any elements to meet the criteria of start with 0 and 1 and 2 and 3. We often list multiple element ID in our schedule as a first digit as an easy way to seperate schedules out by building or by floor for multiple building projects. To fix this, the Element ID Criteria should be bracketed, and each ID starts with line should end in or.

Fig. 1.1 Unbracketed “or” Statements

In Figure 1.1, the ID starts with lines are correctly ending with an or statement to continue to the next criteria line; but they are not bracketed. The result will be windows that start with 0, or ANY ELEMENT that starts with 1, 2 or 3 will show in the schedule. To correct this issue, simply add a bracket before and after the or statements.

Fig. 1.2 Incomplete Bracketing of “or” Statements

The last example, Figure 1.2, shows a partially bracketed “or” section of the Criteria. By not closing the bracket, you will see a warning in the Scheme Settings noting that the Criteria is Invalid! The result will be nothing can schedule until the brackets have been correctly applied.

Hopefully this gives a little more insight into what may be going on with your schedules, and why things are missing, or too many elements are being included.

All Things Grid Tool

First and most importantly it is essential to realize there are multiple parts to the grid tool and its interaction with the various drawings. The Grid Settings are relatively straight forward and simple to understand.

Standard Grid Settings from Template Favorites

Above is an example of our default Grid Element Settings. If you find you do not have a Grid Element in your favorites, you can start with the line types and pen weights shown there. Also note the Naming Rules section; all grid elements have a custom name and are not generated automatically (this requires an automated grid placement that really only works for projects with very regular grids tied to beams and columns).

It is also important to note the upper right corner of the Grid Element Floor Plan Settings dialog. The drop down for Show on Story… allows you to define which stories each grid marker shows up on. I have audited projects in the past that used lines, circles, text, or even duplicate grid elements to selectively show grids on different stories. This drop down allows you to access a custom list of stories to show or hide each grid marker on. For most of our projects, this should be set to all stories for all grids, but if you need to customize this, there is an easy solution in the Grid Element Settings.

The Grid Tool Settings also have a section for Section/Elevation projections of the Grid. It is important to note that these settings DO NOT determine IF the grid will show up on Elevations or Sections, only HOW they will appear on those views.

To properly show Grids on an Elevation or Section, you need to set the Grid Settings in the views Marker Settings.

Elevation Selection Settings for Grid Appearance

To turn on Grids for an Elevation or Section simply go to the Grid Tool section of the Markers Selection Settings and check the box to Show Grid Elements. Make sure that the elevation settings do not have Auto-stagger selected. This feature can be useful, but more times than not it just messes with the opposite views appearance.

As an example, here is a quick mock up of an elevation with a grid offset:

screen-shot-2016-09-07-at-3-00-05-pm

Notice that Grid Element “C” is staggered over the top of Grid Element “B”. This is because the grid has been offset to the left of “B” on the opposite elevation. Staggering a grid element, either manually can cause this overlap. A manual adjustment applies the stagger to all elevation/section views that grid appears on. Automatic staggering should stagger grids appropriately for each view, but any manual changes will revert to the automatic position when the view is refreshed.

In the above example, Grid Element “C” may not need to appear on this elevation, since it is for a structural bearing line that does not relate to this side of the project. In the elevation or section marker settings, this Grid Element can easily be excluded from the Viewpoint of each marker individually. You simply need to go to the Marker Settings and click Selected under Show Grid Elements by Name and exclude the grids you do not want to show on that Viewpoint.

Elevation Settings to Show/Exclude Individual Grid Elements

A Note on Marker/View Types

All markers have three types (with the exception of Interior Elevations, which must be a Source Marker); Source, Linked and Unlinked.

Source markers generate content based on model elements. Linked markers reference an already created source content or view. Unlinked markers are a blank slate that reference not model or drafted content or existing view.

A marker may be changed from source to linked, but any source content will either be missing or translated to 2d elements. This is irreversible, and for elevations and sections, new source markers and subsequent views will need to be created. Linked or unlinked markers can not be changed to source markers. Linked markers may be changed to unlinked markers, and unlinked markers may be changed to linked markers.

Moral of the story; do not change source markers/views to linked or unlinked markers. You can create a work sheet from any view if you need to explode view content, or place a new marker if you need the source marker to reference a different drawing.

SECTION MARKER SYMBOLS

Trying to get your section marker to mask over line work and fills? Here are your settings:Screen Shot 2014-09-26 at 11.13.55 AM

By using the built in Marker in place of the NCS marker you have a setting for a background fill under the marker text, this will effectively mask out what is behind the marker. A few things to note on changing the marker head from the NCS to the Built in; the marker head scales differently, so our standard 30 pt marker (NCS) will need to be a 42 pt marker (Built In) to match, you will need to specify an appropriate masking cover fill for the marker background and a separate solid cover fill for the marker head arrow with white and black print pens respectively.

Once the change is made this should be your result:
