Using current version of Qcad in Windows 11 operating system context with HP 1050E inkjet printer.
I created a file which includes symbols from the electronics library.
I cannot get the symbols to print properly, they show very, very faintly.
Any suggestions?
Hi,
The answer is related to the one given in this topic
I marked your duplicate entry from 10:14 pm for removal. 
A sample file with a few symbols would help us serve you more efficiently.
All line-art is vector art and vectors have no width.
Drawing entities therefor have a Lineweight property.
That can be:
- Inherited from the layer they live on, common practice, Lineweight is ‘By Layer’.
- A custom set Lineweight per entity.
Then avoid a Lineweight that is too narrow so that they are printed fainted or even not at all.
Avoid for example Lineweight 0.00mm or even 0.05mm on some printers.
Lineweight can be set to ‘Default’ and then check the global preferences for the ‘Default’ weight under Application Preferences .. Appearance
All drawing entities live on a layer.
- With ‘By Layer’, then adapt the Layer Lineweight attribute.
- With a custom Lineweight property, then adapt the entity(ies) Lineweight property.
Blocks, ‘Symbol’ blocks their entities also live on a layer.
Then edit the symbols to figure out if they use a Layer dependent or a custom Lineweight.
With an imported Library it is most probably just one dedicated symbol Layer, more common is Layer ‘0’.
Block References in Model_Space are also (single) drawing entities and they also live on a layer.
Per definition, this must not be the same layer as the Block definition entities their layer(s).
Then the ‘By Block’ attribute/property may play a role.

Problem drawing attached.
Thanks for your help and patience!

Model consists of some Border line-art on Layer ‘0’ using ‘By layer’.
- 1 Block reference and some text on Sub-layer ‘OBJECT’ using ‘By layer’.
Lineweight for Layer ‘0’ is 0.25mm and for the Sub-layer it is 0.15mm.
Block ‘block 1’ is some circuit, all line-art and on both layers.
56 objects on Sub-layer ‘OBJECT’ have a custom set lineweight property 0.00mm
51 objects use ‘By layer’ and are on both layers.
Typically the symbol art seems to be exploded art from the 3 other Blocks:
‘pd_hrtb’, ‘res_htb’ and ‘spdt_tl’.
All the art in these Blocks except text have a custom set lineweight property 0.00mm
One solution might be:
- Edit Block ‘block 1’
- Select All (TA) → 107
- Set Color, Lineweight and Linetype properties to ‘By layer’ for all at once.
Not a future solution for using the symbols blocks again is this file because these still use lineweight 0.00mm for some content.
The whole Idea of symbols as Blocks is that you insert a Block Reference where you need a symbol.
It is not required to explode every symbol Block Reference to individual entities.
The idea behind Block ‘block 1’ is that it is a composite symbol in this drawing to reuse at several places.
Otherwise place this content directly in the Model_Block.
BTW: The drawing seems to be hand drawn without any snapping to the Grid or other auto snapping points.
