Moving in walls by a certain dimension

Anonymous — Tue, 22 Mar 2016 20:38:39 GMT

Hello Autodesk Community,

I am fairly new to AutoCAD and was hoping to get some help on a restroom project i've been working on.

Operating on Autocad LT 2015 I have the basic floor plan drawn out and I'm moving on to drawing in details such as the tile.

I want to offset all my walls to indicate the wall tile by half an inch.

The problem I'm having is that if i offset the walls, the outside corners wont meet, and in a room with a lot of ins and outs it can be tedious.

Is there a faster way of doing this??? I attached a image of one of these corners.

Thanks in advance,

Justin

I don't think there is a quick easy way of doing what you want to do, this is where a little pre planning would have come in handy also, do you really need that level of precision? by that I mean after its plotted out can people measure that 1/2"

I don't have LT to check, but I expect it has the PEDIT command. Use that, pick one of the Lines, call for the Join option, select all the appropriate contiguous wall Lines [can be all at once, with a Window, or if other kinds of things don't meet them at their ends, you could just type in All], and some Enters to finish with PEDIT. That will make the contiguous wall Lines into one Polyline. Offset that, and all the corners will be taken care of. If you ultimately want them to be independent Lines again, Explode the Polyline(s). [If LT has the option to handle the corners of Offset Polylines variously, you will presumably want the OFFSETGAPTYPE System Variable set to 0, so that the corners will be square, rather than rounded or chamfered.]

AutoCAD/LT doesn't have "walls": just lines, Plines and Mlines.
If you draw with LINE objects, you need to FILLET to close the gap you drew.
If you drew that L-shape with a PLINE, then OFFSET would behave the way you want.
If you actually use MLINEs, which better simulate 'walls" since as you know a real wall is not just two lines, you'd have to do so much more to clean up the corner but the drawing would be accurate to construction.

FWIW if you want to draw "walls", the correct software to use would be AutoCAD Architecture http://ww.autodesk.com/adt or REVIT (which comes in a cheaper REVIT LT variant).
