| * Always check the small yellow tick on first point of line object. It shows the FREE space side of line. It means you should draw walls in counterclockwise direction, the blocks in clockwise direction, pit or chimney in counterclockwise direction, etc. If you made a mistake there is "reverse" option in "Line commands" section. | * Always check the small yellow tick on first point of line object.

| + | If you are repeatedly creating th2 files with large blank extents around the drawings and images, then it may be because of spurious drawing lines made accidentally when navigating during data collection with PocketTopo, TopoDroid, SexyTopo or the likes. It may also be because of inappropriate parameters used (chosen by you or the application developer) to export data from these applications to Therion.\\ | ||
| + | If drawings and export\imports are well posed, then your drawing area extents should not be much larger than your actual drawing.\\ | ||
| + | You can manually or automatically tweak the drawing area that is viewable for a particular file if you scroll down to the Drawing Area window near the bottom of the right-hand side of XTherion, and make adjustments there. | ||

| - | Note that this works using passages defined by lines of "wall" type (even if their "-outline" is set to "none"). It does not join other types of line. It normally expects to find pairs of lines, one on each side of the passage. If there are multiple passages that need to be joined between pairs of scraps, you can normally use the "-count" option to say how many possible passage joins Therion should search for. | + | The method can only join two scraps at a time.

| - | From time to time the semi-automatic way does not work, or you want more refined control. Then you should join each line to the other line (usually, but not only walls) or to a point. Every point on a line has a mark according its sequence from beginning of line (yellow tick). The first one has mark 0, next one 1, etc., last one is mark "end".

If you have several objects to join at one point, then unlike the scrap by scrap join above, you should use one join statement to join them all (see bottom of this topic).
