Join Jeff Bartels as he covers the most important features of this industry-standard drafting and design application in AutoCAD 2011 Essential Training. This course begins with a tour of AutoCAD's interface and the tools used to create basic shapes. It then focuses on the methods used to modify and refine geometry while emphasizing accuracy and good habits to build a solid design foundation. The course covers using layers, line types, and colors to organize a drawing file and explains how to efficiently annotate a design and prepare it for final output. Throughout the title, Jeff shares industry techniques used in production and reinforces concepts using practical examples. Exercise files are included with the course.
In this lesson, I'm going to show you how to fix a problem that many beginning students run into, when they start using Annotative Styles, and that is, what do you do if you've already annotated your drawing and you find out you've used the wrong scale? On my screen, I have a mechanical example, and this drawing contains several annotations. If I hover over these, you can see they were created using an Annotative Style. Now all of my annotations were created using an Annotative Scale of 1:1 because I made the assumption that my drawing would fit on the sheet at that scale.
Let's take a look at our Layout. This is a standard 11-17 inch sheet and this layout contains a Viewport. I'm going to open up the Layer Control, and I'll turn Layer Viewport on. I will then double-click to get in the Viewport and I'll do a Zoom Extents, so I can see my geometry. Now let's set this Viewport to a measurable scale. I'll open the Viewport Scale fly-out and I'll select 1:1. Here's my problem. My annotations look great, but unfortunately my drawing doesn't fit on the sheet.
Let's try this. I'm going to change the Viewport Scale to 1:2. Notice the part fits on the sheet, but all of my annotations disappeared. That's because my annotations were designed for a 1:1 Viewport and this Viewport isn't 1:1. Let's take a look at how we can fix this. First of all, I know I have to go with this scale, so I'm going to center this, a little better and then I'll come down and lock the Viewport. Then I'll double-click to jump out of the Viewport and I'm immediately going to change this scale such that it's accurate.
Then I'll return to Model space and to fix this, I'm going to go to the Annotation Scale fly-out. I'll set this to what I should have used, 1:2. Then I'll click the Annotate tab and I'll come down to the Annotation Scaling Panel. I'll click this fly-out and I'll select Add Current Scale. This will add the current annotation scale to any object that I select. I'm going to select all of these objects and I'll right-click. Now my annotations are appropriately sized for a half-scale Viewport.
Let's zoom in a little bit and notice, if I place my Cursor over this object, we can see that it has two annotative icons. That's because my annotations are now supporting two different annotation scales. If I select this, notice we can see the other scale right there, that's the 1:1 size. Now this isn't a bad thing, but you know what, I don't need the 1:1 scale version anymore. So I'm going to deselect this. Then I'll do a Zoom Extents and let's remove the unnecessary scale.
I'm going to go back to the Annotation Scale fly-out, I'll select 1:1. Then I'll click the Annotation Scaling fly- out, and I'll select Delete Current Scale. This will delete the current scale from any object I select. I'm going to select all of my entities and right-click. Finally, I'll make sure that the Annotation Scale is set to 1:2, in the event I add more annotations later. Now my annotations look pretty good. I'd like to make one change. These dimensions are a little tight.
So I'll select this 6.00 and I'll pull this out a little and I'll pull out the 3.65. Let's do a Zoom Extents, and now that I'm finished, let's return to the layout. As you can see, I didn't have to erase my annotations since start over. We were able to correct the ones we already had. The only thing, I have left to do is turn off my Viewport boundary. So I'll go back to the Home tab. I'll open the Layer Control and I'll turn off Layer Viewport.
In the event, we annotate our drawing using the wrong scale, we don't have to start over. We can simply add the correct scale and then remove the incorrect one from our annotative objects.
