CAD question



Guys, i need to show insulation in a cavity wall - my boss mentioned that the easiest way to do this was by 'Batting'? - apparently a command or technique in CAD - im not 100% sure on this - can someone help me please and perhaps tell me how to do this?

'Batting' is a line type, rather like dashed, dotted, centre etc etc...

Simply select the line you want to alter, then in the drop down line type menu select "other..." the line type manager window will open. Chances are you will have to load the line type from AutoCAD's library so click "load" then scroll to the line type called, funnily enough, "batting"! You then need to select it in the line type manager which applys it to the selected line you drew.

See the attached .PDF file to see what i mean.

The next problem you have is scalling the line type so that at 1:1 in model space it will desplay correctly. The drawing attached is a 20:1 viewport on a A1 titleblock which obviously plots at 1:1. the line scale of the insulation using the batting line type is 0.14. Confusing maybe but you'll soon understand it

Is that the wiggly stuff shown on your pdf there?

if so looks good, ill have a go at that, looks better than hatching.

Yeh that "wiggly" stuff.....

Normal line type style for insulation when detailing wall cavitys, slabs etc etc
 
hmmm, well i simply cant get it ot scale properly! ive drawn it in model space. Adjusted the line type to Batting and now i cant get it any thicker so that it fits a 55mm cavity. help!

Best way to sort out the scale of a line type is to edit it in the actual viewport in paperspace. First you need to lock the viewport so when you pan and zoom, it wont alter the actual scale the viewport displays.

Highlight the viewport, then right click so the sub-menu appears. Theres an option called "display locked" on the fly-out menu that appears select "yes".

With the viewport locked, double click inside so you can select the model. Now double click on the insulation so the properties menu appears. Now change the line type scale until it looks about right.

If the viewport is say, 1:20, i change the scale to 0.14 for a 75mm cavity.

Edit:

I woultnt use a scale of 1:5 if possible. Its difficult to scale off the drawing once its plotted as scale rules dont scale to that. Use 1:10 if possible
 
ive been asking my boss how to do this for so long now that im scared to ask any more - and you have just explained it within about 10 seconds - you star - it looks wicked now! thanks
 
well the cavity is 100mm but ive just drawn a cavity tray with a lintel above a window and needed to have 55mm insulation within the cavity tray itself. Turned out that at a drawing scale of 1:5 - the linescale was best at 2.80!

Get out now then if your not enjoying it, or major in something away from surveying in your final year. its the type of industry that once your in that'll be it till your old, grey and haggered.

lol - i think its just that i can not stand my boss on my placement year - he really is a complete idiot who totally refuses to help because he is just to 'busy'. Bit of a joke really - anyway - another question. I have drawn a door detail aswel, however, there are three differnet details to show on one page, one of the top of the door with the lintel, one of the bottom of the floor and one elevation. The problem i have is that the door elevation is perfectly readable but the other two are too small. I guess i need to set up new viewports for the smaller ones and re scale them - only thing is - i havent got a clue! Help - the big fat boss aint here to help and im the only other one in the building who even has a clue about how to use CAD - lucky me.

Sorry dude, was out on lunch

you want to set up 1 maybe 2 viewports and use a smaller scale. For example, if your elevation is at 1:20, the details really wana be at 1:10. The next problem you will have is making sure your dims are the right size at that scale. For example, using the same dimension and text size for all your details will mean the smaller scale viewports will show the text and dims larger than those on the elevation(s).

What you wana do is copy the 'standard' dim style and call it 1_10 (colons arent allowed for some reason) then you are given the option to change the settings of the dim style (font type, size, arrow size/shape ect etc) There is also an option to scale the the size of the dimension by a factor. The standard dim style is drawing at 1:1 in model space (or 0.1) you wont to make sure this dim style (the one you called 1_10) is half the original scale, for example 0.5.

Then when puting your dims and leaders on the text and overall scale in paper space will match that of the 1:20 viewport even tho the actual model scale is smaller.

I apologies if this is difficult to understand, its kinda difficult to explain something I do without even realising it

Have a look at this layout.

Notice that the dimensions and text is exactly the same even though the scales to each viewport are different. single/multiline text is an easy one to solve, just scale the text from the 1:20 viewport by 0.5 in the 1:10 viewports

Hope that helps

although - that is exactly what i am trying to achieve - i have three drawings that need to be readable just like the ones on the attached doccument you just provided me with. Each at a different scale but i dont know how to do it!
