Zoom/Pan while selecting entities
When asked to "Select entities" by a command, very often I need to zoom or pan to a specific part of the drawing WHILE SELCTING. Unfortunately, after any pan/zoom operation ICAD draws all entities in their original colors, including the already selected entities - these should be dashed as is the case in ACAD to indicate they are selected. Now, one has to select the entities again to be sure they are selected. Will this be improved in the next release?

Hello Vaclav,this bug appears after selecting entities after command. But... It works good when you select entities before command. In this case, if you don't want use grips, you can switch off with command GRIPS. I tested v. 4.0 alfa and it is the same problem.Vladimir

Well, that'right, BUT selecting entities BEFORE command is NOT working so well either: When I select some entities, then continue selecting, say, by Window, the previously selected entities are DEselected which is VERY inconvenient. I just compared this with standard ACAD - in ACAD the selected entities are kept selected no matter how many times they are reselected by subsequent select commands. The ACAD way is much more logical.I think this is a clear inconsistency (bug) in ICAD - quite different behaviour while selecting depending on whether one selects BEFORE or AFTER command.Any suggestions?Regards Vaclav

Suggestion: Type P to restore highlighting.

Wow! You're right, it works when selecting after the command. I must admit it's a surprise for me, as I would expect the P(previous) selection to refer to the previous fully defined selection (in a previous command), but it's fine to have this option as it is. Thanks for the hint.Regards Vaclav

Just be aware that it only restores highlighting of the most recent selection, not multiple selections.

:-(( Yes, you're right. I was too quick to see it as a solution to the problem - it's not. In a complex drawing the selections are often done by multiple selection so it is still a problem. BTW: My doubts about the logic behind the use of "Previous" selection set mentioned earlier are even stronger now.I believe it should not be a big problem to correct this bug. The program obviously has all necessary information to draw the selected entities dashed even after a zoom/pan. Is it really impossible to correct asap?Regards Vaclav

There is a difference in logic between Acad and Icad here. Acad interprets a "Previous" selection as the combined selections made by the previous command, whereas Icad interprets "Previous" as the latest single selection made, by window, crossing or entity pick. In other words, a much simpler interpretation. Maybe this is a structural limitation in Icad which also makes it hard to fix this bug? Just wondering-

Well, you're right but I think it's not that simple. In some situations, the "Previous" selection set results in a set created by multiple selections as well. For example, start COPY command, make several selections, then cancel the copy command. Now, if you invoke a (COPY) command again, the "P" selection selects ALL entities previously selected which is correct.The problem of not highlighting the selected entities is hardly linked to a difference in "Previous" selection logic - the program allows the user to select quite freely, it only does not DRAW the selected entities dashed, although it 'knows' they are selected (it shows the correct number of entities selected).Also, the earlier mentioned problem with selecting BEFORE command, should be easy to correct as well IMHO. Now, the corresponding method changes the status of an entity's property "selected" in a way like "Selected:= not Selected" while it should be "Selected:= TRUE" (while adding to selection set).

My observation is not exactly like what you describe. Let's say I invoke the Copy command, select using multiple windows then cancel the command. Selecting by previous the next time only selects the very last selection. If , on the other hand, I complete the copy command, the entire selection set can be selected using "P".In Autocad it does not make a difference if the command was not completed.

Yes my description of the steps was not exact. In fact, it is necessary to complete the selection operation, not the command itself. Only then the subsequent "P" selection refers to the complete selection set. The COPY command can be canceled, thoug not before the selection is complete. Quite strange difference from ACAD - not a critical nor the most serious one, anyway...Regards Vaclav

No, not critical from a user's perspective, but it may say something about where the dog lies buried (literal translation of non-english expression). It suggests that Icad has a temporary holder for the selection set, and only updates the "permanent" selection set after the selection operation has been finished. Acad in comparison is continuously/transparently updating the "permanent" selection set, which makes it easier to re-establish highlighting after zoom/pan.I am probably far from understanding the problem here, but a little guesswork never did any harm.

Agreed, including the 'dog', which expression, BTW, is exactly the same in my language (Czech) :-)Anyway, it would be fine to see someone from BricsCad is listening out there and hear his comments and, most of all, some perspective of their handling the problems reported in this forum.Regards Vaclav
