Creating a window figure

[imp24]

I need some kind of help in this type of Problem that our professor gave to us. Currently so far we've been introduced to arrays, mirrors, trim, arc, offset and limits. I kept those in mind since I think they may have to do with the figure displayed below:

 

 

The thing that really bothers me is that I really need to make it precise basing from the measurements given since I still find it hard using coordinates, and I don't know how I can apply the given inches into the exact coordinates that reflects to the given measurements.

 

As of now we're only using AutoCadR14. We're not into 3d yet since we've just started and only focused on the basics. Thanks in advance, I'm really new to this and I'm usually bad at geometric stuff

You are basically laying out a grid. You are not using coordinates.

 

Start with the easy stuff. Each window pane is 15.75x10.5. I'd suggest using the rectangle command to create one then use the array command to set up the correct number of rows and columns.

 

You need to have 28 "panes".

You are aware that you can enter exact dimensions in AutoCAD are you not? You should also be working in architectural units.

[lpseifert]

Coordinate input isn't necessary; use the offset and trim commands.

[ReMark]

You can even skip using the rectangle command and just use the array command along with the commands mentioned in the previous post above.

Regarding the rectangle, if the dimensions are 15.76'x10.50', how am I supposed to input that as first and second corners? Thanks for the answers btw, I'm a slow learner so I wanted to take this one step at a time.

Well the REC commmand does have a Dimension option once you select a first point. U can also click on your first point and enter a relative coordinate, example @15.76,10.5

[totzky]

Check your unit first.

If you start Autocad with English Or Imperial the default unit is inches.

 

15.76' = (15.76 x12) + _______ inches.

 

Check your units first if it is properly set up.

[totzky]

Err! Rgarjr is right. You are already in inches.

[ReMark]

To input dimensions using the Rectangle command you must frist select the Dimension option by pressing . Then you'll be prompted by AutoCAD for the two necessary dimensions.

[imp24]

I think I got it already, but it seems my default unit is in feet since when I tried entering @15.76,10.5 the rectangle became too large. I then tried to convert the given inches into feet just so the rectangle will meet its requirements.

 

Is there a way to change the default units?

I also tried to select the dimension option and tried changing the units but it didn't work [eg changing Primary Units to Architectural etc]

[ReMark]

With units set to architectural AutoCAD will correctly depict a line if it is 2", 20", 200" or 200,000". The rectangle appears to be too large because the default setting of LIMITS for a new drawing is 1'-0" x 0'-9". Thus, your retangle looks really big. Had LIMITS been changed to something larger than the overall size of your window the rectangle would appear more "normal" to you.

 

Direct distance entry for feet and inches in a drawing using architectural units takes the form of 1'7" for example. Notice that AutoCAD does not require a dash between the foot symbol and the numeral 7. Test it for yourself if you do not believe me.

[ReMark]

To keep it simple, change your limits to 10'-0" x 12'-0". That should give you plenty of space to draw your window. Remember you are drawing it full size. You are not "scaling" the window.

[totzky]

I attached drawing done in Acad 14. Hope you'll get something out of it.

 

Commands I used:

1)Ctrl+N

2) DDUNITS (Set to Fractional)

3) Command: REC

RECTANGLE

Chamfer/Elevation/Fillet/Thickness/Width/:

Other corner: @15-3/4,10-1/2

4) D (Annotation, Units

on the right to Architectural.

I was expecting to see a drawing of a completed window. This should have taken you about ten minutes. What's the hold up?

[totzky]

I'm working on it...

[ReMark]

Good then. You've got 9 minutes left. Stop wasting time responding to my inane posts. LOL

[Dipali]

Remark,

do you realize that totzky is not the OP but like you he is trying to help so doing that drawing is not his priority, but the OP's

[totzky]

Well this is the whole window as I understand it.

Whew! I'm a little bit rusty to Acad14.

By posting the drawing here you have helped the student with his assignment, which is against the unwritten policy of the member's at Cad tutor.

we always try to help student solve their difficulties but don't do there homeworks.
