Override the AutoCAD measurement
Tuesday, November 08, 2005
Sometimes, in my current job, I have to go through old drawings. Since I wasn’t the creator of the drawings, I normally have to check all the dimensions to see if the CAD operator responsible for the project didn’t just override the text on the dimensions instead of drawing everything in the correct size.
As you can imagine, this is a time-consuming task because there is no way to tell when you open a drawing whether the dimensions are correct or not.
For this kind of situation, there is a fantastic, Express Tool that can check your drawings or even reset the dimension text to its true value.
You can access this tool from your top pull down menus:
Express Tool menu>Dimension>Reset Dim Text Value
Basically this tool executes the DIMREASSOC command, which if you are like me you may prefer to key in manually.
After executing the command it will ask you to select all the dimensions in question and AutoCAD will highlight the incorrect ones. You can also type in the word "All" to select all of the dimensions. Finally an additional enter will return the dimensions to their true value.
Good luck,
Fernando Salgado

Spline to Polyline
Sunday, November 06, 2005
I work as a structural designer for a sign making company so I receive lots of artwork made with other non-AutoCAD computer programs like Adobe Illustrator and CorelDraw. In those programs when you export to a dxf or dwg file they export the curves as splines, which, at times, is counterproductive.
For the kind of work that I’m doing splines aren’t the best kind of AutoCAD entities. After trying many different solutions to transform the splines in plines, I finally found one which I’d like to share. There some autolisp routines available for that task but after doing some research, I found a way to do it without using any routine or software.
By the way, a Spline is a curved line formed by two or more vertices, or "control points", and a mathematical formula describing the curve(s) between them. A Pline, or polyline, is a line created by a series of shorter straight line segments.
HOW TO CHANGE A SPLINE INTO A POLYLINE
Step 1: WBlock the Spline
Step 2: Open the Spline dwg and Save it as an R12 dwg
Step 3: Save the Spline as a DXF file
Step 4: Insert the DXF into your new file
Step 5: Explode the DXF
Step 6: Pedit the segments as a Pline.
