Doors & Walls – Symbolic or Projected

The symbolic or projected view of a door determines wether it matches the exact 3d settings of the door or is just a graphic plan symbol. There may be cases for both, but it is important to know what the settings do; and find the right combination of settings for both the wall and the door so that they both appear as expected, or in some combinations, appear at all.

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

Relevant Stories

Everyone should be familiar with the Floor Plan Display settings for the various element types in ARCHICAD. Some tools are very flexible in regards to which stories they are visible on, others seem very limited; namely the wall and column tool. With these tools, you only get two options; Home Story Only and All Relevant Stories. So what constitutes a Relevant Story?

For this example, I have just thrown together a couple walls in the ARCHICAD20 Residential Template, but it illustrates the point well enough.Screen Shot 2016-07-26 at 4.46.32 PM

The boundary walls are 12′ tall and extend 2′ to the the story above. The bisecting wall is 10 feet tall and is top linked to stop at exactly the story above. All walls are set to show on All Relevant Stories.

The resulting floor plans are as follows (Home Story left, Above Home Story right):

If this is not showing how you need or expect it to you can adjust the view settings to determine the constraints for a Relevant Story in the view map view settings.

Going to the Roof Story’s view settings, go to the 2D/3D Documents section and click on Floor Plan Cut Plane Settings…

From here, you can define what extents will be considered relevant for this view. If I want the boundary walls to show as cut instead of outline as illustrated in the plan views above, I can drop the Cut Plan height to Current Story to a level that will cut the outer walls. Then if I want to include the interior wall as an outline element (not cut through), I can set the Relative Floor Plan Range: Show down to: Current Story -2′ (or any height that would include this wall.

Screen Shot 2016-07-26 at 4.32.21 PM.png

The result is that the home story for these walls has not changed, all walls are shown as cut just as before, but the story above shows with the taller walls cut and the lower wall as outline only:

One of the amazing advantages of this feature is that a wall may be Relevant for one view, but not for another. Even though the story settings match, the wall height never changes, but the wall appears on one plan view, but not another of the same story. Or it appears as cut in one plan view but as outlines only for another view of the same story.

The default for our floor plans is to have the Cut Plan height to Current Story set to 4′, and all offsets set to 0″, but there are always cases to fine tune this to show or hide elements, or change how certain elements may show in a given view.

 

Smarter Modeling & Top Link Settings

In the wake of our office presentation on Solid Element Operations, I have been getting a lot of feed back, questions, comments and suggestions on use of SEO’s and methods of modeling without them.

I want to point out three scenarios that I came across this morning. One is SEO’s done correctly, the other are wrong. These deal specifically with walls, columns and beams and their relationship to the roof elements above.

Wall parallel to roof slope, extended to ridge height and trimmed with upward extrusion

Screen Shot 2016-04-28 at 9.40.04 AM.png

Columns extended beyond roof plane and trimmed with upward extrusion

The basic idea here is that elements are all extended beyond the roof and then cleaned up by using SEO’s. This is wrong for several reasons:

  • First, this habit will cause more unnecessary SEO’s in the project. And we have already covered why that is problematic
  • Second, these elements can interact, intersect, create voids in elements above, such as dormer walls
  • Third, these walls do not clean up correctly with their roofs in section, wall section, details
  • Fourth, it runs a risk of saving out incorrect or inaccurate IFC or SKP files

The correct method for making these walls/columns/beams flexible to design adjustments is to set them to the correct height relative to the story above. Top link the wall, even if it is grossly below the story above, as in this case where the floor to roof height is 18′ in the story settings; so the top of wall is -9′ to story above.

Moving Elements to a Different Home Story

You may notice that when you change an elements home story in the element selection settings, the elevation (height to project 0) also changes, or more accurately remains the same relative to its home story. This means that if you move a slab from the first floor to the second floor, it will move up the difference in the story settings.

Home story changed from Story 2 to Story 3 (Please ignore the sloppy 3/64″ modeling)

Screen Shot 2015-08-26 at 1.50.47 PM Walls jump to story 3 with same relationship to home story

If, however, you need to locate an element to a new story, but maintain its relationship to project 0, so that it stays at the same elevation but is located on a new story, you will need to relink the elements home story. This is done with a simple right click function, rather than in the element settings. Simply select the elements  you want to change the story settings of, right click, select Relink Home Story… and the elements will remain at the correct height/elevation, but be set to the new home story.
