Thanks! Can you explain (1) how you calculate the fit points, so I can do it myself at home. Already explained earlier: https://www.qcad.org/rsforum/viewtopic.php?f=32&t=10725#p44210 In a Spreadsheet: - Column A: Row 10-82 = values 0-72 (nn below is 10-82) - Column B: = Ann multiplied by 5 => Degre...

@ Jkiss If you could share such a file we could have a look at it. 1400 Line segments should not be an issue but remind that QCAD is basically 2D. If considered proprietary then attach it to a Private Message. Easiest entry point is double clicking on my user name and take it from there. Regards, CVH

About 40 flutes per foot = 12 inches would ideally segment the outside with edges 0.3 long. The outer curve of R = 12.92522 + 0.15 is 20.46241354 long. But segmented it is about 20.46196722 long. We need to keep the width of the developed interior to make it fit laterally, but the length needs to be...

FB, Used the arc of d36_dome_arch_0,1.dxf R = 12.9252188715954 D = 25.8504377431908 Sweep = -89.66656284 (8 digits) => Length = -20.2276670292275 Then the 73 fitpoints are: 5.35380095325549,0 5.33342812427165,1.12793812925123 5.27246468685015,2.25587625850246 5.17137460956051,3.38381438775369 5.0309...

... I think you messed up the title in that last post ... An octagon that spans 35.7 has a face of 14.78742417671961107, not 14.79 An octagon that spans 10 has a face of 4.14213562373105137, not 4.14 The arc is presumed not to be 20.23 long. That looks again as rounded/truncated values. The splines ...

Time to t ry to draw a correct fixed width spline for the cover pieces. Remind that each arc size has its associated spline by Math. If you settle for a certain radius or radii I would gladly provide the fitpoints. The quick draft Excel sheet is still open, merely a question of entering a radius an...

r0berts:

Work around:
- Draw your spline.
- Draw a Leader with arrow somewhere. (Or a dimension for that matter)
- Explode the Leader and 'steal' the arrow deleting the rest ...

FB, The arc in d36_dome_arch_0,1.dxf is CW and tangent to vertical at the right. Similar as what I proposed for the 32" version. - - - - - - The arc in d40_dome_arch_0,1.dxf is CCW and tangent to the top plane. The left side of the vertical box is orthogonal to the 5" line and goes trough the point ...

I'd be grateful if you could share how you would handle a project like mine? I see your problem. Reading another topic on groups it seems that ACAD has something like that. It does not entirely mimic the Block functionality and I read about issues with that. In my wish list I added an entry for som...

Note that the "C:\Program Files\QCAD Professional" part might be different Andrew, ...QCAD/scripts/File does not exist on a standard installation. Only including ...QCAD/scripts/File/Print/Print.js corrupted the tool. A) Print Preview does not switch to preview mode but the Options Toolbar is displ...

The selction includes : 5 lines, 2 splines, 5 arcs and 2 circles. When I move the lot, only one of the splines is offered to preview. This falls under 'Complex Shapes'. QCAD figures out the complexity of the selection and when true the preview is limited. One would then ask why that one spline and ...

@ newyd_cnc, I extract CAM related data to a working file to process with QCAD/CAM. From a master file I can then create as many CAM files as desired, with different things and/or as several revisions. Basically: Don't clutter your CAM source drawing with unnecessary items. And on the other hand: Al...

After reviewing your drawing, A) I drew the cord to connect the two points (...). B) Then I drew an orthogonal line, and trimmed it to the height of the top of the slot (where the arc connects). C) I drew another cord from the top of the slot to the center of the arc, and took that measurement, cop...

Fonctionne très bien pour le rouge ou n'importe quelle couleur ici. En rouge ou affiché en rouge c'est pareil. Je l'ai testé en français aussi. :wink: Dans les versions 3.27.6 et 3.29.4 ... version 3.24.3 a environ 4 ans et je n'en ai aucune copie. A noter qu'il y a quasiment des doublons dans des c...

Bonjour et bienvenue sur le forum QCAD. L'export SVG n'est pas open source, voir : https://www.ribbonsoft.com/fr/documentation/features Et puis nous n'avons pas beaucoup d'informations sur lesquelles nous appuyer pour modifier la façon dont les choses sont exportées. Même à l'aide de scripts. Mais A...
