Hi I came across a strange problem. I was using Autodesk Fusion 360 software for 3D modelling at work. (this is free for educational use and is fairly easy to learn). Fusion 360 has the possibility of creating drawings directly associated with the 3D model which is nice and I was using this to produ...

Are you using QCAD to produce the DXF file? If so, you can very likely simply change the color of your layer(s). perhaps its worth adding, that as QCAD is a mighty fine free and open source CAD program, it can of course be used to edit the DXF file and save it again, eg: use CRL to generate your DX...

I don't think you can draw it directly with a polyline, since you would have to guess the middle point (guessing is bad) but you could draw it like that and convert to a polyline.. however, moving the points will not necessarily do what you want, since the attribute "tangentially connected" will not...

is there actually a requirement that the line terminating at point A is at any particular angle? (ie Husky has made it tangential with the blue line forming the point of A, but you didn't explicitly state that as a requirement..) If you don't have a requirement to terminate at any angle, then I woul...

Hi (from south west UK) how did you enlarge the text in the dimensions? In Edit / Drawing Preferences -> Dimension / Dimension Settings you can change the Text Size, and changing this also changes the arrowhead size in that drawing .. to change it for all (new) drawings, you can do the same in Appli...

do you need to do it once, or many times? It is basically a point on a circle which is rotated as it is moved along. If you need to do it only once (or few times), you can do it as follows: 1. draw a dot at the start point, and select it 2. choose the 'Move and Rotate' tool from the Modify menu 3. T...

I think you have a conceptual error .. perhaps this will help. Obviously, it is not possible to place a rectangle on a point since the rectangle is bigger than the point. What you are doing is picking up the rectangle with a handle and placing that handle on the point! So, if you need to place objec...

I created such a file with a couple of functions, but it shows up in the library browser as a non useable part.. is there a way to prevent that?
Hm ok, if I use a different extension eg 'common.ecma' then it doesn't show up.. would that be the best way?

the little yellow triangle means that the script failed to produce an icon, and the lack of anything in the drawing means that the script failed to produce an object to insert I find that when that happened, there would be an error message on the terminal that I ran qcad on; I don't know how to make...

just as any other part I think you can double click on the 'InvoluteSpur' gear icon and it will open the options window (or single click to select it, and click the 'insert object' arrow at the bottom of the library browser window..) if you then move the mouse pointer to the drawing you will see a p...

Sure, and I will keep working on it for a while too I want to generate an internal ring gear at least, and also this script does not handle undercutting at all - in fact I don't know how to calculate that as in the real world the hobbing tool just does that automatically but it weakens the gear, and...

Hi I wrote a gear generator script for QCAD. implemented as a part library item https://github.com/plunky/qcad-gears So far, generates an Involute Spur gear outline only as a polyline. Can draw an axle hole, and spokes if required. gear.png gear.dxf for dimensioning the gear, you can specify the Pit...

Try to figure out which Fonts are used in Techsoft it can use any system fonts. Thats not so important right now though as if I'm cutting out at work then I don't usually need the annotations Here are two test drawings. One is Attribute Controlled by Layer settings - the other one has customized en...

Hi The Techsoft software does not use .DXF files natively, it uses its own proprietary format but can import/export drawings to .DXF in a limited way. I investigated in more detail today and a file it exported was noted as R11/R12 DXF when I loaded it into QCAD. I took this as a hint, and examined t...

Hello Clive, thanks for your response. Apologies for my tardy response, we are not supposed to be on forums at work and also I was busy most of the day :) The Techsoft version we have (v2.09) fails on many types of .DXF file such as this one splines.dxf which has some splines in it. You may note tha...
