Interesting Composite Glitch

This is an interesting glitch we ran into today in a migrated project (started in AC16, now in AC20). The file runs pretty well for having passed through so many versions of AC, but there is an interesting error in the composites, one that I was able to replicate to some degree even in AC21 (non-migrated file).

If a composites skin separator is set to “off”, it may appear correct in the plan view (view map or project map), but show with remnants of the skin separator in the drawing (view placed to a layout).

In the image above, the line selected is deselected, and even though the pen is set to “21”, which is a white skin separator pen in our template, the glitch occurs.

As you can see above, the composite shows correctly with no skin separators.

However, once placed onto a layout, the skin separator shows in places. Some composites, depending on skin settings and line/pen types, show up.

However, by turning the skin separator “on”, as in the image above, and setting all hidden separators to pen 21/41/61 (depending on composite type), we can achieve the desired results, as seen in the image of the placed drawing below.

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!
