May I add that a closed spline with a minimal point count doesn't display correctly immediately after creation. Although on manual creation the preview looks OK. var sp = new RSpline(); sp.setPeriodic(true); sp.setDegree(2); sp.appendControlPoint(new RVector(138, 81.44444)); sp.appendControlPoint(ne...

Hi, and welcome to the QCAD forum. Seemingly there is no vertical scrollbar for the CAD Tools toolbar (widget). One might consider that as a shortcoming. On the other hand your icons all look rather large. What are the preferences for Applications Preferences .. General .. User Interface? For the si...

For commercial use of QCAD, do we need to purchase the professional version (paid) or can we use the free version (non-paid) for these purposes? IMHO, professionals use professional software and there are certain costs associated with it, those are usually deductible. :Wink: Licence information: ht...

Hi, It is common in CAD to NOT draw at scale, choose a drawing unit and draw everything in scale 1:1 in that unit. This avoids scaling every value forth and back between real world and the digital version in Model_Space. How this is presented on paper in a later stage depends on the paper scale for ...

Emiel, The sum of the interior angles of a triangle is an unbreakable rule, it will always be 180° degrees or Pi rads. That can be exploited to find the third angle when 2 are already known for example. An isosceles triangle with a height of 1142.5 and a base of 1280 long has a top angle of 58.51292...

Why is it you were able see this difference and I am not able to see the difference? Discovered it while debugging the script as it failed to convert the left example to a circle. Additionally in testing for it, I stored the actual value in a variable. var bulge0 = entity.getBulgeAt(0); var bulge1 ...

for some reason any infinite lines inside block reference are not selectable .... I can not replicate that fully in version 3.27.6 nor in 3.29.4.0. Far from the Block reference I can't select the infinite line, as if outside the bounding box of the common items. But the infinite is selected togethe...

Hi, Stacked Block References should be OK. The Attributes like Color, Lineweight, Linetype, visibility are inherited from parents depending several settings and some Preferences. Your attributes can be By Layer, By Block or custom specified. Application Layer compatibility has an influence on Block ...

How were you able to tell the difference between the bulge factors? Both show up as exact 1 in the Property window. Values in the Property Editor are always rounded values, displayed with 0 to 8 digits depending preferences. One can change the the bulge factor of each segment in direct, even in ful...

The reason why I ask is that they do not import the same (I'm importing into a completely different CAD program). Curious on how they are handled differently ... It should not be different at all ... :wink: Could you share a screen caption of the file with polylines in that application? Regards, CVH

Also, the Properties panel isn't showing this information - where can I find it? When selected the red reference marker is the start point. The rest of the info is gathered from the vertices listed in the Property Editor. How do I convert the left to be the similar to the right (change it from 0°, ...

After a circle has been exploded - how to you turn the objects back to being a circle? The answer is partially given in the linked topic: Something we can 'Undo' immediately if we notice it soon enough. When 'Undo' is out of the question there is no easy way back but redrawing. So, Undo ( OO ) all ...

As I indicated in my first post using the "circle2p" command and exploded that - twice - resulting in two arcs. My bad :oops: this is by preference. See Application Preferences .. Modify .. Explode. First it is converted to a polyline. After that you explode the polyline. For me that preference is ...

The QCAD command line tool dwg2dwg converts files between versions.

Is the circle a type of block? No, not at all, an arc and a circle are two distinct basic CAD entities. In normal conditions a circle would not explode at all. Test it, draw a circle with CI for example, select and explode ( XP ) it. The circle entity remains a circle. :wink: What probably happened...
