Need help setting up a drawing in Architectural


Recommended Posts

Posted

I have never done a dwg in Architectural before and have a few general questions. Let's say I am doing the dwg in 1/8" = 1'.

 

1) I have went under UNITS and changed the Length Type and Precision to: Architectural and 0'-0 1/256". A guy here at work told me to keep the Insertion scale on Unitless. Is there anything else here I need to change?

 

2) Under Drawing Setup, I have my Horizontal Scale set to 96.0 which made the Symbol and Text Plot Sizes both 0.0800.

 

3) Under Modify Dimension Style, Text tab, do I need to change the settings since I'm doing a 1/8" = 1'. The Text height is showing 0'-1" right now, and the Fraction height scale is set at 0.625000. Under the Primary Units tab, I have the Unit format set to Architectural and the Precision set to 0'-0 1/16". Do I need to change that to match the above setting?

 

I hate to ask so many questions. I have never done an Architectural dwg and they aren't helpful here at work. They just say do it and figure it out. Thanks and any help is greatly appreciated!

There is no reason to set your precision to 1/256th. Think about it for the moment and it should become clear to you especially if you have ever done any carpentry.

 

Draw everything FULL size in model space. If a wall is 8'-6" long then draw it that length. If it is 4 1/2" wide draw it that way. At some point when you have finished your drawing then you'll switch to a layout (where you have access to paper space), create a viewport or viewports, and assign scales to them. Finally, when you plot, from your layout, you do so at a scale of 1:1. AutoCAD will take care of what is depicted within the viewport(s) and plot it to the assigned scale.

 

Your text and dimensions can go either in model space or in your layout. If you want them in model space then I suggest you brush up on annotative scaling.

Yes, I second what REMARK said. I have a co-worker who insists on working in 1/256 precision. And for the life of me I cannot figure him out except that he is way to **** for my style of work. There is no way on this planet any carpenter or bricklayer or ironworker or concrete, especially concrete workers, can hold +/- 1/4" let alone 1/256". It's just a waste of time.

 

And the other point REMARK makes which I totally agree with is that too often new users waste time worrying about what scale to use or how to set a scale. AutoCAD is a powerful tool which doesn't care what scale you draw in. You can be using inches, feet, meters, fingernail thicknesses, monkey tail lengths or an RCH, ...whatever. You can use ACAD's power to take what you've drawn and make it to any scale you want. Just start drawing in model space and let the software do it's job. That leaves you more time to do your job better.

If you are left wondering what happens after you draw everything at full size the answer is "Layout".

 

One switches to a layout and creates a viewport or more than one viewport depending on what your needs are. Assign a scale to the viewport (ex. - 1/4"=1'0") and then using the pan or zoom commands zero in on the area of interest you want to display in the viewport (ex. - an entire floor plan). Then lock the viewport's display. When it comes time to plot do so at 1:1 scale. AutoCAD will know how to properly depict what is in the viewport based upon the scale it was assigned.
