CAD: An approach to mathematical curves for engineering, part 0, just hackish.

Part 0: Drawing mathematical functions in BricsCAD and AutoCAD. Calculating x and y values with a spreadsheet and drawing the curve in BricsCAD (and AutoCAD, ZWCAD). Post-processing: smoothing and exporting as SVG for LibreOffice, PDF. This is a series about creating mathematical curves in BricsCAD (and AutoCAD).Part 0, just hackish with a spreadsheet, result driven.Part […]

Documenting: LibreOffice Writer Template Changing

Internally, LibreOffice Writer has been used for technical documentation for many years: Writer is very strong in combination with style sheets and SVG format is perfectly supported. Vector-based images can therefore be inserted very well. When you work with large documents, there are two annoying peculiarities you should be aware of. The first is that […]

CAD: An approach to mathematical curves for engineering, part 1, the math.

This is a series about creating mathematical curves in BricsCAD (and AutoCAD).Part 0, just hackish with a spreadsheet, result driven.Part 1, the math, understanding ways to iterate.Part 2, the coding, techniques available. THIS ARTICLE IS UNDER CONSTRUCTION. YOUR POSITIVE INPUT IS APPRECIATED. Introduction Mechanical engineers sometimes need mathematical curves. For example: A satellite dish is […]

CAD: Insert and units

You add an external drawing and suddenly the scale is no longer correct. It is a problem that everyone sometimes encounters. How do you solve that? This article explains the consequences of various unit settings. Do you draw in inches? Or mm? Or unitless? And how are “INSUNITS”, “INSUNITSDEFSOURCE” and “INSUNITSDEFTARGET” set? Do you find […]

Documenting: Libraries from CAD to PDF and HTML Publications

Extracting illustrations from CAD files for documentation is obvious. Organizations can do this smart and inexpensive by using XML. However, little can be found on the net about this. It is time for an example. For understanding the value for your organization, for learning and or for direct use. Part I: What we are going […]
