Here's one other option: CVH likes to approach things from a mathematical perspective, and I like the geometrical approach... To do that you first need a symmetric Catenary curve of the right dimensions. One could use a suspended chain or a heavy rope and trace that before turning it upside down. O...

I have not yet worked out how to create an arch in Qcad where the apex at the top is higher (or lower) than the side radius. An arc is round, isn't it ... :wink: Maybe you need a half ellipse to create a form that is higher/lower than half the horizontal diameter. Downside ... Minor an major radius...

I would like it to be made up of (15) 2.625" segments, not a curve. QCAD has no tool to create an n-sided polygon with a defined side length. But there is a way ... Start the PG2 tool 'Polygon (2 Points of Side)' In the Options Toolbar: Not as polyline, no fill, no corner radius, 28 sides (=2*(15-1...

going over this issue and QCAD in general I don't see an issue with QCAD ... I see odd or incorrect created blocks. I presume that (some) other Apps create a block from entities with the drawing origin as reference point. QCAD allows for indicating a reference point when creating a block from selec...

catenary is derived from Latin for 'chain', and it is how domes, arches, etc have been constructed for hundreds of years True ... But not entirely ... Math tells me that a symmetric Catenary curve spanning 24" with a length of 47.25" (=18*(2.5+0.125)) has a sag of 18.6928". (17 full bricks and 2 ha...

The form will be laser cut from the Qcad document. Usually plywood is used for this, no laser required. I would draw a 180 degree arc with radius 12". Draw a brick (RS) ... A rectangle 4.5 by 2.5 and cut or copy that with reference (RT/RC). For the reference I would use the center of a 2.5 side. Th...

Joseph, In scripting if you have a block reference in the document then one can set/alter its position with: var blockRef; // A reference to a block reference entity (RBlockReferenceEntity) var position; // A valid position (RVector) blockRef.setPosition(position); // One has to recast that to the d...

Jim, The GCodeBase.js you posted on Thu Jul 27, 2023 9:24 pm is not the original from QCAD/CAM Yours start with: /** * Version 1 27jul23 * Include definition of class CamExporterV2 from QCAD/CAM plugin: */ include("scripts/Cam/CamExportV2/CamExporterV2.js"); That should be: /** * This file is part o...

How do I check for ongoing updates? Is there auto-update notification?

If you save a block as a library item then this block is saved as a dxf Please explain this further, It is not possible to select a block from the Block List and save that. One can select a single Block Reference entity and create a library item from that entity (BT), no need for a reference positi...

Jim, Remark that GCodeBase.js may be overwritten by an update of QCAD/CAM. Please read the header of this file. You should not edit that for customizing the G-code output. LxcncIn.js nor JimOffsetIn.js are standard postprocessors. JimOffsetIn.js should create an offset path instead of using G41/G42....

I wasn't expecting to be able to join the splines and keep the ends of each spline exactly as they were It should not preserve tangent orientations ... - The resulting new spline will only match if the two merged splines were actually tangent to begin with. - In all other cases it was a discontinui...

Still, the single addition of a decimal point is by far the easiest method. The tool could include a Scale factor and save that persistent like most other tool options. if I could tell QCAd in the preferences that (for example) all my imported bitmaps should be scaled to 10 pixels per mm. For such a...
