I usually will use standard diagonal hatching for demolition and cross/box hatch pattern for the new construction. I usually also keep the new construction on a separate layer and a different hatch pattern. Personally, I would save a new file for the new construction portion, because you will have to start with the original floor plan, delete the content to be demolished, save the new file (careful not to overwrite) then draw in the new walls, doors, etc. If you make a "wall demolition" layer, would it apply to doors? windows? To most of us who have done this a while it's more straightforward but for some others it isn't always so.Īlso, keep in mind that Floor plans and architectural plans in general are conceptual and 99% of the time what is built is a little different than what is planned/drawn. I tend to think about drawings in a very broad/general way. One option is to start with the existing floor plan (XREF it in if you want or just copy/paste) and just hatch the walls you want layered on a "Demolition" layer or something similar. But with each part of a xref we all could change a drawing, all of our drawings could be changed and all could work off each others drawings.JMO Edited Decemby Currahee I ask, what if we (100 people) were working on your drawing? We would all need the "layer" rules. We learn this in a large number of people working on one file. With working with layers if you give the teacher the drawing whats going to happen if he doesnt know what layer is supposed to be on what? If you xRef it in you have an overlapping drawing (the way xrefs are supposed to be used as). IMO, I would Xref it in, but I am just used to doing Xrefs it in Architecture. For my demolition plan do I edit the original Floor plan to add the new room or do I xref the new room? She also wants to see the old Floor plan and the demo plan in two different viewports in paper space. First I started out with a Floor plan and then xrefd it to my new Furniture plan drawing. So I am having trouble moving forward with my demolition plan. Ratchet that up to 8 or 10 sets, and xrefs start to look pretty good. When you have two or three sets of overlapping layers, along with the associated annotation, it can get confusing in a hurry. Your viewports may each have a subset of layers turned off, but in model space they all have to stay on (you can't turn on a layer in paper space if it's off in model space). The benefit of doing it this way is when you work in model space. If you later add utility plans, say for electrical and plumbing, you can xref the construction drawing into a third drawing and add another set of layers. In the construction plan you'll turn off the set of demolition layers and add a set of construction layers, while the existing layers will be common to both. In the demo drawing you'll have one set of layers that will show the existing features and another set that shows the demolition. Typically, you xref older drawings into newer, so you would start with the demo plan and xref it into the construction plan. If your assignment mandates the xref, you can do it that way just as easily. For a simple existing/proposed/demolition plan, it may seem like overkill, but once you have a 60 page engineering set (all showing different parts of the same model), it is extremely useful. You can come back to the drawing in 3 years time and instantly know what is going on layer wise.Ģ) Provided good layer practices are invoked (entities having their colour, linetype properties etc set to By Layer) and through good use of viewport overrides, you have lots of control over the drawing when you have many different views in many different sheets showing different things. Then the same process is used to show proposed/demolished fences, a proposed kitchen renovation, proposed servicing etc.ġ) Simple to use. Then on Sheet 2, Proposed Floor Plan, in the viewport you are showing the Walls and the Walls_proposed layers, while the Walls_demolished layer is viewport frozen. Sheet 1 is Existing Floor Plan, and in the viewport you are showing the Walls and Walls_demolished layers, while viewport freezing the Walls_proposed layer (i.e. Then setup your paperspace sheet layouts and viewports. Then draw your proposed walls on a Walls_proposed layer. Then place the walls which are to be demolished on a Walls_demolished layer. Good layer management is able to achieve all of this easily.
