lortech Posted May 24, 2010 Posted May 24, 2010 I am still learning autocad 2002. Made a bracket with full dimensions but how do I get the bracket to show as prospective? In the old days in high school, 1980s to be precises, we used drafting tables and shows our drawings with a side, top front and perspective. Is this the way Autocad is still used to show its drawings or, put the item into any mode like that of rhino3d? Also, is there a place on this site to show off work and get critiqued? Quote
Tankman Posted May 24, 2010 Posted May 24, 2010 In the old days in high school, 1980s to be precises. Views are the same in AutoCAD as they were (are) on a drafting table; top view, side views, elevation views. Draw as you see it! Most importantly, know the subject of your drawings. "Also, is there a place on this site to show off work and get critiqued?" Post your *.dwg file, you'll get plenty of input!

I would say that the printed views are the same, however, the way you get the views is a little different in some cases. In my case, (mostly Mechanical stuff), I tend to draw everything 3D in AutoCAD then get the views I need to plot from either the model itself or by slicing it with section planes. I still do some 2D work but only in the case where a single view is needed. Don't even bother with isometric like the old day's... KC Quote
ReMark Posted May 25, 2010 Posted May 25, 2010 You can post your images along with your thread or put them in the Showcase forum. Will you be working in 2D or 3D? Quote
lortech Posted May 25, 2010 Author Posted May 25, 2010 I just want to do what industry usually ask. I don't mind doing both. But if its a simple item, such as a bracket which is my first use of autocad, then 3d will work. Quote

tzframpton Posted May 25, 2010 Posted May 25, 2010 Are you talking about a split view of the object?? That can be done with Viewports... that is how Rhino3D works, there are four different live viewports and each view you can set Front, Back, Top, Bottom, Left, or Right view, along with any 3D rotated view you like.

lortech Posted May 25, 2010 Author Posted May 25, 2010 Perhaps I am still learning on viewports. I see in the menu > view > viewports it has these: Named viewports New viewports Viewport 1 viewports2 viewports3 viewports4 polygonal viewport object I pressed on all of these and its asking for a dimension of the paper? Anyway, here is my sample bracket. Title blocks not filled in. Need to see a sample title block so I can fill it in. My first project after I master the basics, is to design a tough security box to prevent my tools from getting stolen. Its happened twice already. bracket.dwg Quote
ReMark Posted May 25, 2010 Posted May 25, 2010 What's wrong with this picture? Oh, I know, you drew everything in a layout right? Quote
ReMark Posted May 25, 2010 Posted May 25, 2010 Since it appears you are doing a 2D drawing and not a 3D drawing you would need to draw each of the views you want (top, front, right-side and an isometric if required). You drew just one view. Are dimensions to four decimal places a requirement? Here is what is recommended. Draw all objects in MODEL SPACE at FULL size. In this case that would be all your views. Since you are using 2002 annotative scaling (for text and dimensions) is not an option. You'll have to choose between placing your text and dimensions in model space or in paper space. Use a Layout to set up your title block and border. Use a Viewport or viewports to view the various objects you have drawn back in model space. Assign a scale to each viewport then lock the display. Viewports can have different scales if required. They all do not have to be the same scale. However, in your case the top, front and side views should all have the same scale. If you include an isometric it can be a different scale. Do you even know how to draw a 2D isometric using AutoCAD? You have a ways to go it seems. Quote
lortech Posted May 25, 2010 Author Posted May 25, 2010 I see where you are coming from. Do not design in paper space, only in model space. The model is copied live to paper space. Now, if its parts, what create drawings > template should I use? Lots of them. Perhaps there is a explanation of them. I can look it up. Quote
ReMark Posted May 26, 2010 Posted May 26, 2010 The objects in model space stay in model space. They are NOT copied "live" to paper space. Keep in mind that layouts give us access to paper space. The viewports we create in paper space act as windows through which we view the objects we drew back in model space. It is a simple concept. Think of the windows in your house. The objects you see outside (trees, people, vehicles, other houses, etc.) are not copied live into the room in which you are standing are they? If you have a top, front and side view of an object created in model space and you want to have these present in your layout then you would need to create three viewports. Your can use any of the viewport options AutoCAD offers you if they fit your needs you get creative. Maybe it would help if you saw an example of what I'm talking about. Quote
ReMark Posted May 26, 2010 Posted May 26, 2010 This is a quick but very rough example of a drawing using a layout with three viewports. Viewports can be resized using their grips even if you start with one of the built-in viewport options provided by AutoCAD. I left the viewports visible (magenta lines) so you can see there are three separate entities. All objects sit back in model space. Quote
lortech Posted May 26, 2010 Author Posted May 26, 2010 okay, this is just like the old days in drafting now unlike rhino which is a 3d enviroment you can select the right top and front sides by selecting that window. In this case, do you need to take that object and extrude it so it has depth and place it on the side part of the model window? In rhino, its as simple as selecting the entire object, then extrude the object. The top would show the extrusion afterwords. Also, the top I can see is on the upper left corner of the window. Bottom, not sure if that is right side or front side on either object. Quote
ReMark Posted May 26, 2010 Posted May 26, 2010 Views are (from left to right) the top, front and right-hand side. You keep tripping me up by going back and forth from 2D to 3D. Which do you want to START with? Know that it IS possible in AutoCAD to create a 3D object and using any one of a handful of commands generate (separate) 2D views or blocks. I can post a layout that has multiple views created from a 3D object if you'd like. The objects in the drawing above were all created in 2D. Note: The above drawing was done as a part of a 3D class I took at a local community college. Since we had some students who had no drafting background what-so-ever in the class the teacher decided a quick lesson regarding orthographic views was in order. We quickly moved on to creating everything in 3D and using various methods/commands to extract the 2D views we required. Quote
lortech Posted May 28, 2010 Author Posted May 28, 2010 I went to copy/past my model to a new scratch model space but had issues with it getting centered. Seems when It asked where to paste it, I just pressed 0 and 0 again. So now its centered. Now the issue is the dimensions are going off the screen in paper space. How to rectify this? Also, can 4 view ports transfer into four images on paper space? I have uploaded the changed bracket for viewing. Now, need a depth view for the model and paper space. bracket.dwg Quote
ReMark Posted May 28, 2010 Posted May 28, 2010 Perhaps your dimensions weren't associative. Did you check DimStyles? Quote
