Ahh I see that I have made an ambiguous post! What I meant to say is that, like the gable line tool, changing the roof pitch in the wall DBX does not turn off the auto rebuild roofs. That is a subtle difference between changing the pitch directly on the roof plane and doing it by other methods that relate to the roof.

What Dermot said! Plus using the Q&A part of the forum will lead to a plethora of very helpful colleagues who are sitting on the edge of their seat to help each other with interesting problems and challenges. I know that I am. One of the best reasons to use CA for doing professional residential designs is the wealth of the user support group. That and CA is among the best of category for custom house design. Unless you are doing a subdivision, it is the leader in doing individual house design. Like any complex tool, you need to get over the wall of being fluent in the use of the features and subtle adjustments that can be accomplished using CA. The tutorials go a very long way to getting you to that point. For example, there is a tutorial on using a gable wall modifying line that lets you maintain the automatic rebuild of roofs, while having different pitches. If you try to change the pitch of a roof directly, that will turn off automatic roof rebuilds. Same thing for changing the roof pitch by clicking on a wall and editing the pitch on the roof dialogue in the wall DBX. Here is the roof gable line tutorial that I am referring to:

This is a good idea, and should be in the suggestion forum.

The floors for this building are cantilevered. The framing illustrated will definitely not work. The joists should run into the main building for at leas 6x the cantilever. This is a project for a structural engineer to specify and provide structural drawings. At least in my opinion.

And property boundaries would all be in even metre increments? It would be useful to know the need though.

1000 mm grid snaps would make your cursor jump 39.37 inches at a time. How would this be useful? It takes more than playing a Canadian to be a Canadian. You have to have maple syrup for blood.

A snap grid of 1m is way too big. I can't imagine that being used for anything practical in designing houses.

One metre increments are very big steps. Do you mean that you want to design in metric then using a metric template is a good place to start. This is available when you first launch CA. Click on the "New From Template" and you will be given a choice of which template to start your drawing from. Hope this helps

Since the limiting distance in 9.10.15.4 for allowing any windows is 1.2m, any setback less than that prohibits any windows at all. So, for zero lot line setback up to 1.2m there is no need to do calculations because for the Canadian building code. The code also says: (2) Where the limits on the area of glazed openings are determined for individual portions of the exterior wall, as described in Subclause 9.10.15.2.(1)(b)(iii), the maximum aggregate area of glazed openings for any portion shall not exceed the values in the row of Table 9.10.15.4. for the total area of the entire exposing building face based on the limiting distance of the individual portion. So this restriction is not based upon the WINDOW size but the GLAZED area. CA does not automatically calculate that.

Do you mean the opening in the wall or the actual glass area of the window? The window area (including frame and all other components for mounting the glass) are baked in calculations that CA does automatically and can show on the schedule. The area of the glass not including mounting components is not tracked by CA but can be calculated using a custom ruby macro.

I am experiencing the same problem with X-13 and Windows 10 64b pro. The number of crashes has been reduced, but I lay the responsibility for this pretty squarely at the feet of NVidea. The only thing that I think that CA could do is somehow program a trap that still allows work up to that point to be saved. For some reason auto save seems to stop working sometime prior to the fatal crash and abend.

One more question, does this only happen with NVidia? Any of your experiencing this with AMD or any other cards?

Have any of you notice something strange with the auto-save feature before one of the dreaded device removed crash. It seems to me that auto-save stops working at some point prior to the crash. It may be that there are a few things going wrong with the program's functioning before the device removed crash occurs. The most frustrating thing is that this crash, that seems to be related to camera views, completely abends (makes the internal processes) stop entirely, except for the ability of the program to display the crash notice. There is no way to do a save. The exit is fatal to anything that you did from the last time that you opened the plan and layout file. Thoughts and observations anyone?

Rob is so right! Demot, I have owned CA for a while now and can download older versions if I need to use them for any reason (I haven't found one yet, but I can imagine doing work for someone else that has an older version and wants it maintained in that version). If you buy a new license, will CA let you download and use an older version that predates your first use of the product?

Here is an old video on "California Room Addition". Great job by the author.

It can be done, but it is really awkward to do in CA. Most times I just cover this off with a note pointing at the valley. This note reads "Board 1 x 10 Flat on Existing Sheathing".

Here is an illustration of how the plank is laid flat on the roof. Note the sheathing is removed for clarity, normally the sheathing outside of the new roof is left in place, while the sheathing under the new roof is partially removed for air circulation. .

Yes just like that. So far as I can tell it is pretty much the same everywhere in North America where shingle roofs are used.

The valley rafters are normally on the flat over the other roof structure, not on edge as CA generates then though.

Do you have truss selected in the roof DBX?

Have you made a report to tech support? This looks like a bug to me, especially if you had automatic birdsmouth.

Brother Printer https://www.brother.ca/en/p/MFCJ6945DW This does it all. Two trays (I load them 8 1/2 x 11 and 11 x 17. Prints both sizes flawlessly, scans up to 11 x 17 in colour and isn't all that bad on ink. Had mine for a year now with no problems at all.

CA Blocks can also be edited without exploding since X13. Just saying.

With AutoCad you can edit blocks in place to change line weights and edit text etc. Just saying.

Good news for some of us, but there is the same problem with GTX cards as well, such as my GTX970 running on Windows 10 64b Pro. Hopefully, they will solve that issue too.
