ToDos:
|
||
- check for elements which have the attribute "display:none" (some groups have this)
|
||
- inx:
|
||
- set speed manually or pick machine (epilog) - travel and cut speed are prefilled then
|
||
- calculate cut estimation with linear or non-linear (epilog) speeds > select formula or like this
|
||
- select time estimation for specific speed percentage for for all speeds (100,90, ...)
|
||
- select material (parameters -> how to???)
|
||
- select power of CO² source
|
||
- add fields for additional costs like configuring the machine or grabbing parts out of the machine (weeding), etc.
|
||
- add mode select: cut, engrave
|
||
- add some extra seconds for start, stop, removing parts, attaching material, ...
|
||
- Handlungsempfehlungen einbauen
|
||
- verweisen auf diverse plugins, die man nutzen kann:
|
||
- migrate ungrouper
|
||
- pointy paths
|
||
- cleaner
|
||
- styles to layers
|
||
- apply transforms
|
||
- epilog bbox adjust
|
||
- wege zum Pfade fixen:
|
||
- cut slower ( > muss aber auch leistung reduzieren - inb welchem umfang?)
|
||
- sort
|
||
- chaining with touching neighbours
|
||
- remove path
|
||
- remove modes/simplify
|
||
- find duplicate lines
|
||
- visualize results as a nice SVG rendered check list page with
|
||
- red/green/grey icons (failed, done, skipped) and calculate some scores
|
||
- preview image
|
||
- statistics
|
||
- export as PDF
|
||
- run as script to generate quick results for users
|
||
- check for old styles which should be upgraded (cleanup styles tool)
|
||
- check for elements which have no style attribute (should be created) -> (cleanup styles tool)
|
||
- migrate styles from groups/layers to path styles (cleanup styles tool)
|
||
- self-intersecting paths
|
||
- number of parts (isles) to weed in total - this is an indicator for manually picking work; if we add bridges we have less work
|
||
- number of parts which are smaller than vector grid
|
||
- add some inkex.Desc to all elements which were checked and which have some issue. use special syntax to remove old stuff each time the check is applied again
|
||
- this code is horrible ugly stuff
|
||
- output time/cost estimations per stroke color
|
||
- add check for stroke colors -> make some useful predefinitions like (for default modes)
|
||
- black = general cutting
|
||
- blue = cutting inside
|
||
- green = cutting outside
|
||
- pink = vector engraving
