Task Description
There is the Synchronize attributes feature which works well. But It affects only block references in the active layout(modelspace, block layout). If I want to synchronize attributes of block references in in another blocks, i have to manually go through all blocks and run synchronize attributes feature. That is the reason I would like to modify Synchronize attributes feature to affect all block references in a drawing, or add new Deep synchronize attributes feature.

1870 | QCAD (main) | Feature Request | Low | Stretch tool / option to turn selection restriction on... | Assigned | |
|
Task Description
Hi,
since 3.19.2 the Stretch tool looks for any selection and follows the specification “Only stretch selected entities if there is a selection”.
That is a nice feature but it leads many times to confusing because I have to deselect a selection just because I need to use the stretch tool on something else on the fly. The same if I “forgot” a selection outside of my zoom which is still important for me. The stretch tool just won’t work without any message why not. My routine now is that I terminate every selection just before I use the stretch tool just not to be surprised by “why isn’t it working”?
It would be nice to have in the Stretch option bar a checkbox to turn the “only selection feature” on or off. QCAD should remember that setting.

1903 | QCAD (main) | Feature Request | Low | Saving layer settings, e.g. visibility status, associat... | Assigned | |
1 |
Task Description
In a medium complex drawing it may be too much details to have all layers in a drawing visible at once.
Instead a number of views would be created that saves not only zoom level and position but also what layers are visible and not (as appropriate for the purpose of that particular view). This is very cumbersome (to the extent it is not really realistic) to achieve today and requires a lot of duplication of both model and layers.
The advantage of adding this is the ability to have only one model (with multiple views) and avoid duplication of work and the risk of inconsistency inherent with many copies of the model.
As a further (and natural extension to this) would be the ability to used this functionality with view-ports to be able to create (possibly many) paper-spaces from a single model. This would however require view-ports to be aware of what view they are a window into. A single change in the model would then propagate to all defined view-ports and paper-spaces.

1915 | QCAD (main) | Suggestion | Low | Viewport does not rotate view-port when changed in pape... | Assigned | |
|
Task Description
To reproduce
1. Select a new view-port in model-space 2. Select the appropriate paper-space 3. When the paper space opens change the angle of the viewport.
Actual
The object in the viewport changes but the viewport itself remains unchanged
Expected
That both the view-port and the object changes angle as the angle is updated
Motivation
If you abort the placement (but keep the angle) and go back to model-space and then redo the operation the view-port is rotated along the angle. It seems that the viewport only picks up the initial angle once the paper-space is open and ignores any changes thereafter
Workaround
1. Select the view-port per normal in model-space 2. Open the paper-space and set the wanted angle but do not place the view-port in paper space 3. Abort the placement on paper-space and redo the whole operation
Once the paper space is opened again the view-port will have the chosen angle

Task Description
To reproduce
1. Select a new view-port in model-space 2. Select the appropriate paper-space 3. When the paper space opens change the angle of the viewport to 90 degrees 4. Place view-port in paper space 5. Select the view-port in paper-space by clicking it 6. Try to move the object itself in the view-port (by clicking the “top” dot) to the right by moving the mouse to the right while holding the left mouse-button.
Actual
The object in the viewport moves down vertically NOT to the right
Expected
The object moves to the right
(It seems mouse movement does not compensate for the rotated angle of the viewport)
Workaround
None, except compensate for the angle in your head and moving the mouse the “wrong” way when correcting the placement of objects in the view-port

As these serve a purpose in some processes, trails of them can be part of the results. For some users Null / Null-lenght are meaningfull, for other users these produce errors down the line. In a few cases its a desirable feature eg. controlpoint spline. (Allthough there are no Null props involved with equal successively controlpoints)
Many problem post on the forum are related to Null - Zero and so on.
In some cases it can’t be undone by re-editing the drawing. https://qcad.org/bugtracker/index.php?do=details&task_id=1925
If it can’t be undone by Undo/Redo it is a bug. https://qcad.org/bugtracker/index.php?do=details&task_id=1757

1934 | QCAD (main) | Feature Request | Low | Diametric text - overlaid | Assigned | |
|
Task Description
Diametric text is always placed above a horizontal measurement.
I often want to indicate both the inside and outside diameter of an object e.g. a wheel using diametric text. The text is overlaid and illegible.
To avoid text overlapping, I use Horizontal Aligned because I can control the position of the text to avoid illegible text.
A better method would be to alternate the placement of diametric text (alternatively) above and below a measurement so that in the majority of cases an overlap would be avoided.
Similarly for a vertical measurement, the text is overlaid and illegible.
When the angle is almost vertical, the angle controls the side the text appears however it also reverses the direction of the text (which is logical but not attractive).
Kind regards Simon

This is a trim method I am missing in Qcad.
20 years ago it existed in CadKey. You had a bunch of lines or segments. You defined a (new) line or segment as cutter. ‘Trim All’. You pointed at the side of the cutter entity to trim all intersecting at that side.
Pritty the same as in this topic: https://qcad.org/rsforum/viewtopic.php?t=5221
Only in rare cases I can use Husky’s workaround as pro. It all depends on what else is in the clipping rectangle that is needed to trim all intended. If of no use all single crossing entities have to be chosen one by one.

Task Description
When working with multiple Viewports with different scale it could be very useful to have extra properties controlling how dimensions are rendered in the viewport:
1) E.g an extra “Dimension Scale” under “Scale” in the Viewport selection’s ‘Specific Properties’ section, could allow having the same size when printed. This Dimension Scale would be multiplied on top of the Scale value, but only for Dimensions rendering.
2) Toggle button for hiding any dimensions in the Viewport. Maybe this should be controlled by being able to specify a Layer that should be hidden in this Viewport only, then I could select my Dimensions layer here.

2018 | QCAD (main) | Feature Request | Low | Layer visibility setting per view/view-port | Assigned | |
6 |
Task Description
In a medium complex drawing it’s often too much details to have all layers in a drawing visible at once. Also, it is of great importance to be able to have a single model to avoid duplication of work and risk inconsistency.
So i would like to create a number of views where each view has selected layers visible (that makes sense for the purpose of the view) and then assign the views to different layout blocks (using view-ports) in paper-space to be able to setup printing of several views on the same page/PDF
This also means that view-ports would have to be aware of what view they are displaying (if any besides the standard-view). This will then make it possible for printouts of different views with selected layers visible (different for each view and view-port) and still have only one model. Today this is not possible.
As it is today the only limited workaround is to set the layers you want to display, print/PDF of that viewport on separate page, and then change it for the next page, and so on. The big drawback is that you cannot have two different views/view-ports on the same page with different layers visible. Also, for large drawing it is painful to have to do a lot of manual setup for each rendering of the complete drawing.

Task Description
Previous Feature Request #1285, dated 2015, incorporated in QCADPro 3.24. I regularly adjust linetype scales on hidden, centreline and phantom lines to achieve the best appearance on the drawing when printed. I note the Paint Properties feature copies all the attributes of the chosen line but does not copy the scale. I have to change the scale of each line, even after ‘painting’. This copying all Properties is something AutoCAD does. I know I could change the line to Hidden2 etc. and tick the ‘scale lines’ box in Drawing Properties but that is not always successful- copying properties is a quick and useful way of achieving the required result.

This could be a new view mode that turns of the view of the interior/pattern of the hatch but leave the boundary of the hatch. Or the draft mode can be extended to include simplified hatches while modifying.

2 |
Task Description
I would like to request a new kind of snap: a “Restricted Intersection” snap that appears at the point where an entity would intersect with a line drawn from Relative Zero that fulfills the current EL criteria. “Restricted Intersection” snaps would be similar to other Relative Zero-based snaps (like “Perpendicular” and “Tangential”), but would predict the point of the snap from the EL constraints instead of the characteristics of the entity being snapped to. Naturally a value of 0 for angle or length would result in that constraint being ignored.
Additional operational flexibility could be achieved by allowing the snap to exist regardless of whether EL is actually in use. To be useful this would probably require determining snap locations based on angle OR length as opposed to angle AND length.
Implementing this new snap would allow, for example, for easily drawing a line of unknown (but determinable) length at a specified angle between a given point and a given entity (see discussion here), with the “Restricted Intersection” snap ensuring that the endpoint of the new line forms an intersection with the entity in question. Currently the same goal can be achieved a couple of different ways, but they all involve at least two separate steps.

Looks like error, but may be that’s feature request.
CAD software uses typical navigation behavior as: Wheel = Zoom; Ctrl+Wheel = Scroll up/down; Shift+Wheel = Scroll left/right.
Any other software like browsers, office software (openoffice writer, ms excel and so on), 2d paint software like GIMP (Photoshop and so on) uses other behavior: Wheel = Scroll up/down; Ctrl+Wheel = Zoom; Shift+Wheel = Scroll left/right.
Users, that intensively use CAD and other software simultaneously prefer to make same behavior in their applications switching CAD scroll to plain mouse wheel.
QCAD’s “Application Preferences”: “Graphics View: Navigation”: “Mouse wheel/ two finger swipe”: “Scroll” allow user to assign scroll up/down to wheel mouse instead of Zoom. But there is mistake Ctrl+Wheel didn’t change to Zoom. Ctrl+Wheel continues to scroll up/down, as the wheel. Wheel = Scroll up/down; Ctrl+Wheel = Scroll up/down; Shift+Wheel = Scroll left/right. No zoom!
Draw manipulation at this mode like a hell: you need to use wheel in conjunction with Ctrl/Shift to point draw in desired position, than move your hand to +(-) for make desired zoom.
