Linear dimensions create distance measurements between two points in the XY plane of. Creating Linear Dimensions. CAD tip # 3249: Question CAD %. How to rotate a view in paperspace (layout)? Taught by Jeff Bartels as part of the AutoCAD 2009. Creating rotated linear dimensions provides you. I would like to create a similar set of dimensions. Linear dimensions (aligned and rotated). Dimension breaks on dimensions or multileaders. Automatic Dimension Breaks To create an automatically. Home / AutoCAD / AutoCAD Isometric Text and Dimension. What about dimensions? You also have to create. Add Text to Dimensions: Print. Tested in AutoCAD 2009 : Average Rating: 3. Dimension Tips (Circles and Lines Auto. CAD Tutorial)1 Dec, 2. By: Lynn Allen. Two features found in Auto. CAD 2. 00. 8 can tame your misbehaving dimensions. As I was traveling and sharing a variety of Auto. CAD tips recently, I found two very cool key dimensioning features in Auto. CAD 2. 00. 8 that somehow sailed in under the radar, and it’s about time the word got out! It is a rare application that doesn’t deal with some type of dimensioning. Over the years we have come up with so many clever means of getting the final dimensions we need for the perfectly drafted design. Www.autodesk.com/autocad-blocks 3 How to Create a Dynamic Block. Dynamic Blocks in AutoCAD. Home / AutoCAD / Controlling UCS for Angled Drawing and. Now when we create rectangle, linear dimensions. I have created a rotated ucs but the ID points.We have learned the advantages of associative dimensions and the disadvantages of dealing with them after they’ve been exploded. The Dimbreak Command. The first dimensioning tool, Dimbreak, takes us one step closer to getting our picture- perfect dimensions without risking the wrath of our drafting instructors. Figure 1 shows a typical case of crossing dimensions. In the past we might have exploded a dimension, followed with a break to follow proper dimension standards. The Dimbreak command was added to Auto. CAD to avoid just such a situation, and its intelligent- breaking facility continues even when the dimension is moved. The Dimbreak command is simple. Select the dimension line you wish to break, and then select the dimension(s) or objects that the dimension line crosses. Figure 2. Use the Dimbreak command to break a dimension without exploding it. The great thing about the Dimbreak command is that the broken dimension is smart enough to reheal itself should it be moved to a location that no longer crosses the originally selected objects. The great thing about the Dimbreak command is that the broken dimension is smart enough to reheal itself should it be moved to a location that no longer crosses the originally selected objects. Figure 3. A dimension line that is broken by DIMBREAK can reheal itself if needed. And if I move the broken dimension line somewhere where the break needs to be modified, DIMBREAK is smart enough to sort that as well. Figure 4. Dimbreak recalculates the break when necessary. Let’s take a look at Dimbreak step by step: Command: Dimbreak. Select dimension to add/remove break or . If for some reason you can’t get the exact break that you want, a handy manual option lets you decide where the break should go. However, if you manually break a dimension, it won’t be smart enough to automatically update should you move the dimension. Dimbreak works on the following object types: linear dimensions (aligned and rotated)angular dimensions (2- and 3- point)radial dimensions (radius, diameter, and jogged)arc length dimensionsordinate dimensionsstraight multileaders. Unfortunately the following dimension and leader objects do NOT support dimension breaks: splined multileaders“legacy” leaders (You are expected to use the new multileaders for leader dimensions.)A few obvious situations also do not support the Dimbreak command. If you have a dimension that is part of a block or xref, Dimbreak won’t break it. You can, however, use objects within the xref or block as cutting edges to break a dimension. Dimbreak won’t let you place a break on an arrowhead or dimension text (which you wouldn’t want anyway). Last, both the dimension you wish to break and the object it crosses have to be in the same space (paper space or model space). You could, however, use the manual option to get the desired result. If you want to control the size of the automatic break, you can do so under the Symbols and Arrows tab in the Dimstyle command. Figure 5. Use the Dimstyle command to control the automatic break size. The Dimspace Command. Let’s move on to another favorite: the Dimspace command. For years we have manually moved baseline dimensions to space them evenly. Of course, we typically guestimated the spacing, moving them until they looked good enough to the naked eye. The Dimspace command takes the guesswork out of evenly spacing our dimensions and gets the job done quickly as well. Figure 6. Unevenly spaced baseline dimensions can cause us grief. Rather than grabbing each of the dimensions and tugging at them until they look OK, you can use the Dimspace command. Dimspace can be used on linear or angular dimensions. Command: Dimspace. Select base dimension: in most cases the dimension line closest to the part. Select dimensions to space: select those dimensions (other than the base dimension) you want to evenly space. Select dimensions to space: Enter value or . In ourexample, the base dimension is the one nearest to the part. Figure 8 displays the result of Dimspace for our example. Figure 8. The resulting spacing is perfectly even! If you choose the Auto option, Auto. CAD will multiply the text height of the base dimension by two to determine the spacing. I noticed the Help file indicated that the selected dimensions must share an extension line for Dimspace to work — definitely not the case as you can see in my examples. You can also use Dimspace to align linear and angular dimensions end to end by using a spacing value of 0. That means if someone has moved your continued dimensions so they no longer line up, you can use Dimspace to straighten them! Figure 9. Uneven continued dimensions can be tricky to even out perfectly. Click the image for a larger view. Figure 1. 0. A spacing of 0 evens up the continued dimensions. Click the image for a larger view. Give these two dimension tools a try on pesky misbehaving dimensions. You might just find yourself with a few extra minutes on your hands. Until next month, happy Auto.
