SolidWorks 2014 introduces the ability to find and use virtual sharps on the on-the-fly while creating dimensions.
- Start any dimension tool.
- Right-click on model or sketch geometry
- Choose “Find Intersection”.
- Left-click on any model or sketch geometry that intersect the first selection.
- The Virtual Sharp element is automatically added, the point is automatically applied as a selection for the dimension tool.

This information was previously posted as part of another article, to which Vajrang Parvate (SolidWorks Corp Sr. Manager, Drawings Development) replied with an additional helpful hint. I’m reposting as a separate article to highlight the information.
Deleting Dimensions behavior
SolidWorks has a new user-selectable behavior when a dimension is deleted. If the user deletes a dimension or even just removes text from a dimension, SolidWorks has the ability to automatically realign the spacing of the neighboring dimensions to get rid of gaps caused by that deletion. The user has the option to turn this ability on by going to Tools>Options…>Document Properties>Dimensions to select the Adjust spacing when dimensions are deleted or text is removed checkbox.
Undoing the deletion
…When the “Adjust spacing when dimensions” checkbox is checked and SolidWorks moves in dimensions after one is deleted, two commands are added to the undo stack : one for the deletion of the dimension and another for the movement of the rest of the dimensions. So hitting Ctrl-Z will undo the deletion in two steps.
One of the funny little things that SolidWorks used to do is that when one added a center mark to a hole (or set of holes) that are already dimensioned, it would not adjust the dimension extension lines to fit with the center mark.
In the march to quality improvements, SolidWorks has fixed this little oversight. Now, when one adds a center mark to a previously dimensioned hole, a gap appears between the center mark and the dimension’s extension line. The same is also true if one adds a dimension to a hole that already has a center mark. No more dragging extension lines after the fact.
Here’s the sample image from the What’s New file:
Adding dimensions to parts on drawings is now quicker in SolidWorks 2010 with the addition of Rapid Dimension. Once the user enters the Dimension command, Rapid Dimension allows the them to quickly position dimensions (almost automatically) as they are added. Not only will dimensions automatically space out correctly as they are inserted, they will be inserted at the correct location, even without that location in view.
Now, each time a dimension is added to a drawing, SolidWorks will pop up with a pie, divided into two pieces for linear dimensions or four pieces for radial dimensions. (Technically, these pies are called the rapid dimension manipulators.)
Each piece of the pie represents the direction (which side of the part) that the user can choose to place their new dimension. When the user selects the half or quarter, the dimension is placed in the correct location on that side of the part within the drawing view.
Two methods can be used to select the dimension location using the pie. The user can simply LMB click on the portion of the pie in the desired direction. The user can also use a mouseless method, by pressing tab to toggle between the pieces of the pie; then press the spacebar to select. Additionally, the user can choose the ignore the choices offered by the pie to manually place the dimension, just as they would in previous versions of SolidWorks.
The auto-spacing between dimensions is determined by the user’s settings in Tools>Options…>Document Properties>Dimensions within the Offset distances field. The ability to set default dimension line offsets has been in SolidWorks for quite some time, but it’s never been quite so useful as it is in Solidworks 2010.
Within a few minutes of using Rapid Dimensions, many users will likely become instantly addicted to the new function, as it promises to be a major time saver when detailing drawings in SolidWorks 2010 and beyond.
One additional item about dimension placement is SolidWorks behavior when a dimension is deleted. If the user deletes a dimension or even just removes text from a dimension, SolidWorks has the ability to automatically realign the spacing of the neighboring dimensions to get rid of gaps caused by that deletion. The user has the option to turn this ability on by going to Tools>Options…>Document Properties>Dimensions to select the Adjust spacing when dimensions are deleted or text is removed checkbox.
One comment I’ve seen about ASME suggests that it is geared towards fully detailing product definition. One trap that rookie designers and engineers will often fall into is over-specifying their parts by placing manufacturing process information on the drawing.
The new designer may do this because maybe a machine shop made the part wrong and was trying to work the rookie’s inexperience to weasel out of their responsibility. Maybe someone in Quality Control was confused by a drawing because they don’t have adequate blueprint reading skills, so they come to the new designer to ask that more information be spelled out on the drawing (when it is already fully specified). These are just a couple of examples. Often, new designers don’t know why manufacturing processes are not included on drawings, nor even that there exists standards that forbid it.
ASME Y14.5-2009 (and previous versions) states:
1.4(d)The drawing should define a part without specifying manufacturing methods. …However, in those instances where manufacturing, processing, quality assurance, or environmental information is essential to the definition of engineering requirements, it shall be specified on the drawing or in a document referenced on the drawing.
It is usually pretty obvious when manufacturing methods are necessary to the engineering requirements, even to the individuals new to the field. Unless one is in particular industries, manufacturing methods are almost never required. A drawing should fully detail the final product without over specification.
ASME Y14.5-2009 adds as an example:
Thus, only the diameter of a hole is given without indicating whether it is to be drilled, reamed, punched, or made by any other operation.
The manufacturer is responsible to provide a final product that complies with the drawing regardless to the processes they use. It is still important for designers to know the processes that will most likely be employed, so they know that the product is economically manufacturable. This does not mean that they should unnecessarily limit the manufacturer to particular processes.
There are a ton of subtle improvements in SolidWorks 2010 to improve its usability. Many of these improvements might seem small now, but once one is reliant on the new functionality, it will seem like we’ve always had it this way. Attaching annotations to dimensions is now easier with expanded capability. Here’s a couple of examples showing-off these new capabilities.
Drop Annotation Notes into Dimensions
It is now possible to drag an annotation note and drop it onto a dimension, to become apart of that dimension callout. First, LMB click and hold on the annotation note.
Then, simply drag that annotation note on top of the dimension.
The result is that the text from the annotation note is now included within the text of the dimension. One limitation is that the dimension field still does not support borders around selected text.
Attach Annotations to Dimensions
Other types of annotation that can be attached to dimensions include GD&T feature control frames, datum feature symbols and surface finish symbols.
- Annotations and their leaders may now be attached directly to extension lines.
- GD&T annotations now may be dropped right into a dimension callout and then detached with the use of the handles in the upper left corner.
- Annotations may now be moved around extension lines, and more easily moved from one attachment to another.
