214 — Blockouts, rectangular and round¶
A hole with nothing built into it — for a pipe, a duct, a conduit, a sleeve.
Note
This lesson also exists in the browser. Work it in ConstructiVision on the web — same steps, same values, so you can follow either and end up with the same panel.
Two dialogs, one idea¶
Program Options → Rect Blockouts and → Round Blockouts. Six of each, kept as separate features rather than one with a shape switch — a rectangular blockout is width and height, a round one is a diameter, and keeping them apart means neither dialog asks for a number that does not apply.
No size palette, and by now that tells you something¶
Like dock levelers and unlike windows, neither blockout dialog offers common sizes. Same reason: a blockout is sized by whatever passes through it.
That is a readable signal. A feature dialog with a palette has usual sizes worth starting from; one without does not. You can tell how standardised a feature is by whether the product is willing to guess.
Six each, so twelve holes¶
Six rectangular and six round are separate limits. If you are running out, it is worth asking whether several of those holes should be one larger opening.
Blockout, or rough opening?¶
Blockout |
a hole for something to pass through |
a hole something gets framed and fitted into |
The geometry can look identical. What differs is what the shop and the site expect to happen at that hole — which is why they are separate features.
Both are checked against the corpus¶
sbvar and rbvar are watched by the corpus review — worth
more here, again, because nothing is steering you toward a usual size.
What to take away¶
Rectangular by width and height, round by diameter, six of each, no presets by design. If there is no palette, the product is telling you there is no standard answer.
