Altium questions
« on: May 07, 2023, 01:38:35 pm »
Hi,
Please may i open this for all Altium problems? (save creating new post each time).

I am not able to put a component from a certain library in to  my schem......i cant detect this library even though its there. It is in fact the original lib from which the schem was first created.
Strangely , i made my own schlib and it can see that.
How do i make it see this other sch lib?

Thanks, that was really helpful.

Locating centrum of a dpak footprint....
Ive now just copied a DPAK footprint into my own library...but its centrum is not marked, so i cant drop it on the centrum in the footprint editor.
Do you know the best way to find the centrum for a DPAK?....in Eagle i just draw construction lines and where they cross is the centrum...is that the right way to do it in Altium?.....as you know, the centrum must be known, and marked,  as its needed for the pick n place coordinates.

Hi,
Noddy version of Altium
Are there any youtube vids or docs, which give "altium for contractors"...ie people who just need to get a small board done and dont have the time to get into the myriadical depths of Altium?
Altium could do with a cut down  "noddy" version...so contractors can just do something quickly, in the initial period when they dont have time to delve into the depths of PCB layout jargiography.
Or is there a "noddy altium" video , which shows you just how to do the basics, manually, in Altium?
Like an EAGLE  version of Altium......Eagle is learnable within a day.

Copy and paste in footprint editor
Hi, I am doing right click copy paste, and CTRL C, CTRL V, but they dont always work.......i am trying to copy a line and move it 2.8mm to the left......the copy and paste only seems to work if you paste right over the top of the line that you just copied, is this correct?

When you do ctrl-v the next click is on the object you want to copy, and picks the pickup point. Then you can go to where you want that reference point to be and paste it. So you select the part, copy, click the reference point then paste it. For a line pick the end of the middle, then move as needed and click to place.

It’s intuitive after a few. You can do the same with multiple parts too.

In the footprint editor, Edit > Set Reference > Center will set the component reference to the geometric center of the pads.  This isn't always what you want (for example if all of the pads are to one side of the component), so you can also do Edit > Set Reference > Location and then click where you want the reference to be.  It's not necessary to move the primitives around in the footprint to center them, although you can do that.  Drawing construction lines to establish geometry is perfectly valid in Altium, although

as its needed for the pick n place coordinates.
Altium will generate a pick-and-place file without a marked center, just based on the component reference, but a marked center is definitely good practice.

Ehhh, I don't think the Altium team need anything else to distract them from the core product  :P .  In all seriousness, Altium is a much more sophisticated tool than Eagle.  There's vastly more capability and baked-in automation of data handling, and while it's easy to say 'but I never use X or Y or Z', the application workflow still depends on those things being in place, and adding an option to remove them makes the software more complex, not less.  Even if it's simpler for the user, it's more complex to develop, meaning more opportunities for problems to crop up.  (It's something of a law of software development that the simpler it is to use, in terms of effort:results, the more complex it is to write and maintain.)  Aside from which, you'd have to decide which of those features a "contractor" potentially needs, which first requires deciding what kind of design work a "contractor" does.  The answer to the latter is "could be anything" and therefore the answer to the former is "all of them".

If you continue with Altium and put some effort into understanding the workflow I think you'll find that it's largely worthwhile in terms of productivity and capability in the end.

Multiboard project and checking PCBs and SCHEMS are all synch'd?
Hi, Am modifiying a 17W SMPS on a PCB, which is one of three PCBs which all belong to the same multiboard project. The circuitry on the three PCBs is across some seven different schematics.
I have done some changes.....how do i push them through to PCB?...is it hit Design then Update..?....

When i have done this, and hit "execute changes", then close......then when i hit  Design -> Update again....   ....shouldnt it tell me that the schematic i am working on is correspondent with whats on the PCBs?

How do i know if the seven schematics have components, designators,  and nets on them, which correspond to what's on the three PCBs?

Unrouting nets in PCB editor
Hi, Currently re-laying out the circuitry on a PCB…need to delete all polygons and nets and stitching and thermal vias on this PCB. How do I do this? How do I know if a thermal via has been done as a component, or just added in to the PCB?…if it’s a component, then as you know, I cant just delete it.
Some of the traces, when i highlight them and click properties, they say "N/A" to the net name...does this mean they are not nets, and that i can just delete them......i ask because in Eagle, you cannot delete nets, because the PCB and SCHEM then become desynchronized. Is it same in Altium?
Now, when i delete the polygon, it leaves its outline there, and even offers me to repour...but i just clicked the "bin" to delete it? How can i get rid of polygon pour and its outline?

Moving net wires about in SCM editor
Ive searched but cant find a good video on moving nets about in Altium schm window. (eg when tidying up a schem) Its nowhere near as easy to do as Eagle. In Eagle, it “knows” what you want to do, and you just grab net wires, and move them about as you please…Altium is far less easy with this…it doesn’t seem to know where you want to move things, and moves things in to “silly” places. Takes much longer. What am I missing?

Stop line snapping in Library footprint editor
Hi, I just tried to draw a 0.2mm silkscreen line outside of a courtyard “box” line on mech 15…..it wouldn’t let me do it….it constantly kept snapping to the mech 15 line….how do you make it snap to the grid lines at 0.1mm, instead of to the mech15 line?

If you need to delete everything, you can use the filter tool to filter out polygons, then just highlight everything and press Delete. Same with the vias.
https://www.altium.com/documentation/altium-designer/pcb-filter-panel?version=18.1

If a trace has no net, maybe the net has been deleted from the schematic at some point. If you delete the trace in the PCB you are not deleting a net. Again you could use filter and find no-net traces, select them all and delete if you want.

Polygon just press delete to delete it. You can also go to the Polygon manager and look there.

Components in schem are from which library(s)?
Hi, Thanks,  Just trying to find out how to get a list of the components on a schem page, and what library they are from?

If they are defined, and not any, I think its in the component parameter table?

RTFM :=\

Or do this



or

https://www.altium.com/documentation/altium-designer/tutorial-complete-design-walkthrough

or

https://www.ece.ufl.edu/academics/altium-designer-video-tutorials/

It's all there and the online help made by altium is actually very usable. But as usual, you will not bother to try and find answers by yourself and revert to a forum instead with a zillion questions which you can answer by yourself if you would put a small tiny bit of effort in studying the manual. Don't be scared now. You might learn something.  :box:

Unknown pin error...cant push schem to PCB
<<EDIT...NOW SOLVED.....Altium was somehow putting in A footprint from another library....which had the same name and shape etc......it was in a  different library, so i dont see how Altium got confused...i think this is a bug in Altium?..END OF EDIT>>
Thanks, ive done a number of tutorials and will do more.
Just downloaded a 7447714470 inductor model for Altium (from the wuerth website), with 3D, and put it into my library...then put it into the schem, and pushed it through to PCB...but it gives an error "unknown pin L101-1".....i dont understand this.....the pin is  clearly in the SCHLIB, and its clearly in the PCBLIB....so howcome it says its "unknown"?
....Ok, now solved by deleting the inductor from schem..then pushing thru' to PCB...then re-inserting the inductor in schem...then pushing thru' to PCB all over again....seems like a "round the houses" way of doing it?
....Now getting  "unknown pin" error with another inductor...and this time it wont solve like the above...anyone know how to solve?
...Now solved that, but strangely the silkscreen dot  which marks pin one of the inductor, isnt appearing in the layout editor....do you know why?
(its a "dotted" inductor).

Any duplicated part identifiers?  DId you run an annotation on the schematic too?

Project has "closed up"
Hi, When i previously opened the multi board project, it showed me all the files in it in the Project window.....now i cant see those files, and can pretty much only see the project name....how do i get the "opened up " project view back? I cant open the files in the project at the moment...the SCM and BRD files.
<<EDIT NOW SOLVED by closing out of altium and re-opening again....END OF EDIT>...is this the best way to do it?

Surely you'd just double click the project folder... no  ???

Why a special topic for Altium questions?  Plus it means we can see if it's a question of interest if there is not a unique subject line.

Cant select resistor or its designator in pcb editor
Hi, Altium keeps selecting the chip on the bottom layer whenever i try to select the res on the top, or its designator......Eagle has a "next" button for this....does Altium?

Hi, PCB routing
Just routing up a PCB now…plenty of google/manual  searches not revealing the following…
How to pick the via size when you change layer
How to actually properly change layer
How to set the clearances for the various net class’s

Keep getting kicked out of licenced operation
Hi, got kicked out of the licence in Altium again....how do i get back to the licence page?....i am just doing it by going on a 10-15 minute wild click splurge until i end up back at the licence page...but how to get there quickly?
