The new Layout Book in PlotMaker 3 is great, but one thing that got harder is getting the plans to line up from sheet to sheet.
In the old days, we would nail down the position of one plan in its layout, save as, and then use Drawing Usage to switch out the plan for another. This ensured that the plans were always lined up.
In the new layout book, you can copy a layout but you can't switch the link to one view without switching all the copies of that link. I view this as a non-feature. Tough luck, we need a workaround.
The answer is to place hotspots in Archicad, on each story, and align those hotspots with the grid in PM.
For this purpose we have the object Drawing Area JAM8. It represents any of our paper sizes, so you can see how the plan drawing will lie on the printed sheet. The templates containan instance of this object an the layer +Z Drawing Area. The object is set to display on all stories.
Choose the appropriate size in the settings, then move the object around until you are satisfied with the position of the plan. Notice in each corner there is an 'L'. This represents the limits of the layout.
Place a hotspot on each 'L'. Use the note layer of the drawing type you are working on. (+A Arch Note, +S Struct Note, etc.) Select all four hotspots, group them, and lock them. Copy. Go to each story and paste. After pasting, select the hotspots and lock them. (You can copy locked elements, but when you paste they unlock.)
When you import the views into PlotMaker, these hotspots will be detectable. If there are no elements beyond them, the frame will fit to the hotspots. If there are (driveway, etc.), you will need to stretch the frame back to the hotspots. (Use the arrow tool!)
Once the frame is sized correctly, drag it into place. Issue the drag command, then grab the frame by the upper-right corner. Now type S, then S again. This makes the cursor snap to the layout grid. Drag the frame to the upper right corner of the topmost, rightmost whole grid square. Let it snap there, then drop it. It should now line up all the way around.
Type S again to take the grid snap off. Rinse and repeat.
Grid snap used to be switched by the escape key. It's better now.
(Extra credit: If you read the Archicad user guide about hotspots, you will find that their sole intended purpose is alignment in PlotMaker. They are a little more useful than that, but not much. I almost never use them. The ghost story and the user origin make them unnecessary.)
