One of the pleasures of using Allplan is the excellent range of 2D drawing tools available...
Please note Allplan 2006 only uses the Advanced Point Entry which supersedes some of the described methods below - revision to follow once 2006 released.
Introduced in Allplan 2003 the Advanced Point Entry was optional.
Trim Lines to element - Available from 'Modify->Draft' tools.
Although fairly straightforward for single lines there is no Help guidance on how to use it with multiple lines.
The trick is to select the whole line - thus you need to use one of the multiple selection techniques available in Allplan e.g. the 'Open Brackets' feature (a shortcut is to right-click in empty workspace) or draw a selection box or 'fence' around the lines to be trimmed - or what can be very effective (if you remember to turn it off after using it!) is the filter assistant tool 'Select elements intersected by...' rather than the default setting of 'Select elements fully bounded by...' Once you have selected your multiple lines to be lengthened or shortened Allplan asks you to indicate the reference line and then asks for 'an additional point' - this seems to be the part of the lines you want to keep but I would experiment this with as I sometimes get unexpected results.

Update September 2004 Although this command has been improved to allow trimming to a 'virtual' line - there is a bug that causes any line trimmed to an arc to extend to meet the arc at both ends of the line. Still there in Allplan 2005.
the 'System Angle' tool to 90 degrees for the example to work correctly.
Anyway... Click the Smartfit tool icon (as above) , select your pattern and Click the OK tick button - Allplan asks you to enter the outline of the region to be filled with the tiled pattern. You can do this manually but the 'Outline autodetect' tool is available.
This tool in Allplan is fantastic - my old CAD system was excellent at this but Allplan is even better! - it takes endpoints and intersections in its stride - Click within an outline or delineate one by hand - press 'Esc' when complete - to add or subtract areas click the 'plus' or 'minus' boxes in the dynamic toolbar and outline another area and again 'Esc' to complete... repeat as often as necessary and then hit 'Esc' one extra time - your pattern appears on the end of your cursor - put it down somewhere - Allplan asks you to show how you want it tiling - I pick the bottom left corner (I placed a point here when creating the pattern) a copy of the pattern appears fastened to your cursor - and then I place it a top left - Allplan asks for the tiling position the other direction and I pick the bottom left (the pattern is now 3 patterns high for some reason) and copy it to the bottom right - Allplan thinks for a minute and then offers an outline of a 3 x 3 set of patterns on the end of your cursor - now I find that it is best to 'drop' this within the area you wish to fill - I suppose you can 'snap' to a point if you wish - it may be important with some patterns - once dropped Allplan does quite a bit of 'thinking' - don't panic if it looks messy! When finished the Smartfit dialogue reappears in case you want to fill other areas. To finish off you might try...
Paint out the edge line Allplan leaves to the region boundary or use
to 'explode' the patterns (and lose the 'intelligence') and then
to 'explode' the polylines (so that you can delete individual lines)
Update 09.10.01 - see also Tips & Tricks Page 4 for a couple of issues.
Chamfer tool and scuntions - tapered reveals to windows and doors are the bane of every draughtsman who works on old buildings - they seldom repeat exactly in angle and so you cannot assume that you can draw one and copy it elsewhere - also the wall thicknesses often vary. Allplan comes to the rescue -
Drawing up triangulated surveys - This neat tool on the point assistant tool bar called 'offset by radius' prompts for circle centre, point or radius and then again for a second and then offers points of intersection between the two circles to be chosen. I use it in conjunction with the 'create point symbol' when drawing up surveys. Much quicker than drawing regular circles and then having to delete them after each pair of measurements.
Parallel lines at equal centres- To subdivide a space between 2 parallel lines (such as a stair outline in 2D plan or glazing bars to a window) draw the 2 lines, then click 'Parallel lines' tool, click the first line, then click...
'Division Point' tool on the Point Assistant toolbar, choose the first line endpoint, then the second line endpoint, the 'no. of sides' pop-up will appear and you can enter the number of subdivisions required, press 'Enter' and temporary points will appear showing the subdivisions, press 'Enter' to select the default position of '1' , the first parallel line appears and the offset is entered into the command line enabling the remaining lines to be created just by pressing 'Enter', (confirm which side is the offset for the first line so created and thereafter just repeatedly press 'Enter').
Modify Offset - available from the main 'Edit' menu or 'Shift+Ctrl+A' this tool works in 3D as well as 2D and is just wonderful... it is hard to desribe in words but basically operates as a stretch tool with an orthoganol lock built in - for all those times when you need to stretch a roof slope in section for example where you do not want the pitch to alter... if there is no reference line handy just click the line you want to move twice and it will reference itself. Diagram coming when time allows...
Drop Perpendicular - this little tool is another gem on the 'Create->Draft' menu - I use it all the time to 'freehand' draw any box shaped object or close the ends of 2 parallel lines. Diagram coming when time allows...
Middle point between 2 parallel lines - need to locate the midppoint between a pair of parallel lines - use the 'Angle Bisector' tool from 'Create->Draft'. Diagram coming when time allows...
Sketching /Freehand drawing - Hold down the 'Alt' key. This creates a polyline. The 'granularity' or segment length is set via the 'Create->Freehand Line' tool. I usually set this to around 0.75 for units set to mm. See also under Top Tips page 2 here.
Change pens in the entire (or part) drawing - Useful sometimes when you have imported a drawing with 'wrong' pens. The same technique applies to change any pen property (group, layer etc. (see below for layers).
Click 'Modify Format Properties->' then click the tick boxes for the line type or thickness you want to change TO.
In the Filter Assistant click 'Filter elements based on a pen' or use the 'double chevron' button to match an existing line on the drawing. At the command prompt it will ask you to Indicate the Elements to be modified - draw a box round all the elements required using the middle mouse button (you can further use the polygonal boundary tool here or more filter options (see Top Tips page 2).
Derive Circle - Available from 'Create->Draft' tools. A most impressive tool for making circles fit between other elements. The many options available are described in an example page in the online Help (F1) and copied here .
Transfer measurements to command line - It is not explained anywhere as to how the measure tool can be used to transfer a measurement to an active command input. The simplest example is the Calculator - available under the 'Tools' top menu bar. Activate the calculator and press the double chevron button which brings up the measure tool dialogue. Measure some existing element. To transfer the measurement to the input line of the calculator just click on the measurement within the list given by the measure tool - easy when you know how (it only took me 6 months to find this out). Drawing commands can be 'interrupted' by clicking on the Measure Tool and the input transferred to the command line in the same way.
Office 2D Toolset - Just in case the settings ever get wiped and for general interest here are my main 2D drawing toolset and the Point Assistant tools which work in tandem. I change these about from time to time but these are the core functions I use every day. 3D tools I bring in as required and using the 'Com' functions (double right click an existing element to create another).
2D without 3D - you can use all the time-saving 3D tools - like walls, windows and doors just for 2D if you wish. In the 'Tools->Options->Architecture' dialogue untick the 'Create 3D elements using 2D'. This prevents the display of 3D attributes - if you change your mind later on then use 'Modify->Architecture->Architecture->Restore 3D view' to show the 3D attributes - this will also re-check the option in the 'Tools->Options->Architecture' settings previously described.
