Hi again,
It is a shame I cannot see what you are actually doing - drawing a wall (or all 'four' for that matter) should only take a split second and dragging them to the required dimension another second. I suspect the problem here is that your walls are not at right angles and I am guessing that you are trying to type in a length and expecting it to alter the angle of the connecting walls. (Interesting that I have used the program for so many years and never had to type in a wall dimension - other than testing of course).
IF walls are supposed to be right angles, them make sure that ORTHO is turned on (Status bar - lower right of screen). This will ensure that they
ARE right angles. Then, when you drag the blue marker on the wall (or Nudge it with the arrow keys) both or any connecting walls will extend as they should and you will see the measurement change in 5mm increments (if that is what Nudge is set to).
If the walls are not at right angles (as yours obviously aren't) then you must have the correct degree of the angle, so the wall that connectes the other two joins to the corners. You cannot extend one wall and expect the angle of the connectiong wall to change its angle - it will always stay at the angle it is drawn, so it must be drawn at the correct angle in the first place. You can set the default angle in Settings / Programme Settings / Drawing Aids and use the Status AngleSnap to make it snap to the correct angle as you draw it (or you can type the angle into the Commander Bar - but that gets confusing to me). Now you can use the blue centre point of the angled wall to drag (or nudge) to the dimension you want and both walls will extend, the angled wall keeping its angle. By the way, Nudge only works to move objects or walls (by selecting the Blue marker) - it does not work to Lengthen things.
Does this seem as though it addresses the problem or am I still missing the point?
As you would have noticed above, Brian has started to put together some simple instructions and he has sent them to me to check first, to see if we can make this easier for people. The walls are probably the simplest things to do in the program and I can't understand why so many seem to have problems with them - really they are just 4 clicks to make a rectangular (or even angled) building.
So to your specific questions:
1) How do I draw a quick and accurate wall?
2) when I have done this, how do I stop the programme altering other walls.
1) Click where you want the wall to start, move the mouse at the angle you want it to be to lengthen the wall and click when you reach the length the wall should be. Continue moving the mouse (at right angles to the original wall -or whatever the angle it should be) and click again when you reach the length of that wall. Do the same again and again (if there are 4 walls) and make sure the final join meets where you started and snaps together. If you want you can now turn on Auto Exterior Dimensions (Tools / Dimensions) and if the dimensions are not exactly correct, drag the blue marker of any wall (or Nudge) to make the length of the walls exact.
2) You cannot fix walls in one position (except ALL of them on one Location). Exterior walls should move with other walls if you drag one - otherwise they would break and floor and roof could collapse. If you want to drag an Interior wall just for one room and it is part of a continuous wall, you must break the wall (right click) in two places and drage then ends in from the break. You can now move the part of the wall between the breaks, then stretch it out to meet another wall, or lengthen the other walls to join up to the new position.
OR (even easier maybe)...
You could select the part of the wall you want to move, right click Duplicate, click the wall you want to duplicate then type in the Commander bar the distance you want to move it (eg 1000mm) and the angle (180 degrees) and the wall will position exactly where you want it. Then delete the old one and extend the other two walls to connect to the new postion.
Hope that makes sense - needs an image so I may add that shortly.
